Are your products made with real diamonds and gemstones?

All our diamonds and gemstones are 100% authentic and come with a certification of appraisal.

What diamond grading system do you use?

Typically we use an in-house system to help reduce costs to the customer, but we base it on GIA grading standards to meet the highest industry standards.

How do the "Four Cs" work?

The "Four Cs" are a system developed by the GIA to grade diamonds. They stand for Carat weight, Cut, Color, and Clarity. Carat weight measures the size and weight, Cut relates to how well it's shaped and faceted, Color assesses its lack of color, and Clarity evaluates the presence of inclusions and blemishes. Each C determines the diamond's quality, beauty, and value, and they all play a crucial role in purchasing decisions.

What are the 4Cs of diamond quality?

The 4Cs of diamond quality are Cut, Color, Clarity, and Carat weight. These are the internationally recognized standards used to evaluate and describe the characteristics of a diamond. Here's a brief explanation of each:

Color: Diamond color refers to the presence of any noticeable hue or tint within the stone. The Gemological Institute of America (GIA) grades diamonds on a scale from D (colorless) to Z (light yellow or brown). The closer a diamond is to colorless, the higher its value. However, diamonds in the near-colorless range (G to J) often appear white to the naked eye. 

Clarity: Clarity measures the presence of internal and external characteristics or flaws, known as inclusions and blemishes, respectively. The GIA clarity scale ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions visible to the naked eye). Most diamonds fall within the range of slightly included (SI1 and SI2) to very slightly included (VS1 and VS2), where the inclusions are typically not visible to the naked eye. 

Carat weight: Carat weight refers to the size of the diamond, specifically its weight. One carat is equivalent to 200 milligrams. Larger diamonds are rarer and can be more valuable, but it's important to consider all the 4Cs together. A well-cut diamond can appear larger than a poorly cut one of the same carat weight. 

Considering the 4Cs in combination is crucial when selecting a diamond, as they all influence the overall quality and appearance of the stone. It's essential to find the right balance based on personal preferences and budget.

What does it mean "cut" mean for diamonds?

The term "cut," in regards to diamonds, refers to how well it has been shaped and faceted. Proper cutting maximizes the diamond's brilliance, sparkle, and overall visual appeal. A diamond's cut is evaluated through four factors, including proportions, symmetry, polish, and brilliance, fire, and scintillation. The GIA grades diamond cut quality on a scale from Excellent to Poor, thereby helping buyers understand its worth. Although color and clarity are essential to a diamond's appearance, a well-cut diamond will impact its overall value. Therefore, selecting a well-cut diamond is crucial to ensure its optimal beauty and sparkle.

What diamond shapes are available?

We can make our diamond jewelry in most shapes, if you find something and you would like it made in a different diamond shape, please send us an email to info@nivetta.com it the item setting you wish to get along with the diamond shape, carat weight, clarity and color you wish to get it in, and we will get back ot you within 12 to 24hrs.

What does "eye clean" mean?

"Eye clean" is a term used in the diamond industry to describe a diamond with no visible inclusions or blemishes to the naked eye under normal viewing conditions. The diamond clarity scale ranges from Flawless (no visible inclusions) to Included (visible inclusions). Usually, a diamond considered "eye clean" has a clarity grade of VS or higher. However, the term is subjective, and an expert should assess the diamond in person or through detailed images or videos before making a purchase decision.

Do white gold rings turn yellow?

Yes, it is possible for white gold rings to turn yellow over time. White gold is created by alloying yellow gold with other metals, such as silver, palladium, or nickel. The resulting alloy is then plated with rhodium, a white and reflective metal, to give it a bright white appearance. However, the rhodium plating on white gold rings can wear off over time due to normal wear and tear, exposing the underlying yellowish hue of the alloy. This can cause the ring to appear yellowish or slightly off-white. The frequency of rhodium plating maintenance depends on various factors such as the wearer's body chemistry, daily activities, and how often the ring is worn. Typically, white gold rings may require re-plating every 1-3 years to maintain their bright white appearance. It's important to note that this yellowing is a surface issue and does not affect the structural integrity of the ring. Re-plating the ring with rhodium can restore its original white appearance. If you notice that your white gold ring is turning yellow, it's recommended to take it to a professional jeweler for rhodium re-plating. They can clean and re-plate the ring, bringing back its bright white shine. Regular cleaning and maintenance can help you keep your white gold ring looking its best over time.

What are conflict free diamonds?

Conflict-free diamonds, also known as ethically sourced diamonds, are diamonds that are mined and traded in a manner that does not contribute to or support conflict, human rights abuses, or environmental harm. The term "conflict-free" specifically refers to diamonds that are not associated with the funding of armed conflict, particularly in regions where diamond mining has been linked to civil wars or human rights violations. The diamond industry has taken steps to address this issue through the Kimberley Process Certification Scheme (KPCS). The KPCS is an international initiative established in 2003 that aims to prevent the trade of conflict diamonds. It requires diamond-producing countries to implement measures to ensure that diamonds are mined and traded in a responsible and ethical manner. To be considered conflict-free, diamonds must be accompanied by a Kimberley Process certificate, which verifies that they have been sourced and traded through legitimate channels. This certification ensures that the diamonds have not been used to finance armed conflicts. Furthermore, many jewelers and diamond suppliers have implemented additional ethical sourcing policies and certifications beyond the Kimberley Process. These include responsible mining practices, fair labor standards, and environmental sustainability. When purchasing a diamond, especially an engagement ring, it's important to inquire about the diamond's origin and ensure that it is certified as conflict-free. Reputable jewelers will be transparent about their sourcing practices and provide guarantees regarding the ethical nature of their diamonds. By choosing conflict-free diamonds, consumers can support ethical practices within the diamond industry and contribute to positive social and environmental impact.

Yes, all our diamonds are conflict-free to the best of our knowledge, we work with industry suppliers that follow the standards set out by the Kimberly process.

What is the difference between 10k, 14k, and 18k gold?

The difference between 10k, 14k, and 18k gold refers to the purity of the gold used in jewelry or other items. The "k" stands for karat, which is a unit of measurement for gold.

10k gold is made up of 10 parts gold and 14 parts other metals, such as copper or silver. It contains 41.7% pure gold.

14k gold consists of 14 parts gold and 10 parts other metals, making it 58.3% pure gold. It is a popular choice for jewelry as it offers a good balance between durability and gold content.

18k gold is made up of 18 parts gold and 6 parts other metals, resulting in 75% pure gold. It is considered to be more valuable and luxurious due to its higher gold content.

The choice between these gold types depends on personal preference, budget, and desired gold content. Higher karat gold (like 18k) is generally softer and more prone to scratches, while lower karat gold (like 10k) is more durable but contains less pure gold.

What is the difference between a natural and lab-grown diamond?

The main difference between a natural diamond and a lab-grown diamond lies in their origin and formation process: Natural diamonds:

Natural diamonds are formed deep within the Earth's mantle over billions of years under intense heat and pressure. They are mined from the Earth's surface through various methods. Natural diamonds are prized for their rarity and unique characteristics, which are a result of their natural formation process.

Lab-grown diamonds: Lab-grown diamonds, also known as synthetic or man-made diamonds, are created in a laboratory environment through a process called chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT) method. These methods simulate the conditions that occur naturally to grow a diamond. Lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds.

Here are some key points to consider:

Composition: Both natural and lab-grown diamonds are made of carbon atoms arranged in a crystal lattice structure.

Rarity: Natural diamonds are rare, and their availability is dependent on geological factors. Lab-grown diamonds can be produced on-demand, making them more readily available.

Cost: Lab-grown diamonds are often priced lower than natural diamonds of similar quality and size. However, prices can vary based on market demand and other factors.

Ethical and Environmental Considerations: Lab-grown diamonds are considered to have a smaller environmental impact compared to diamond mining. Additionally, lab-grown diamonds are conflict-free, as they are not associated with the ethical concerns sometimes associated with the mining of natural diamonds.

It's important to note that both natural and lab-grown diamonds have their own unique characteristics and appeal. The choice between them often comes down to personal preference, budget, and ethical considerations.

Are your diamonds certified?

Yes, all our diamonds are certified based on the industry's highest standards.

Can I see the diamond's certificate before purchasing?

Sure if you would like to get a video or photos of the diamond you wish to purchase you can email us at info@nivetta.com and provide us with the details of the diamond you would like to see.

How do I choose the right diamond for my engagement ring?

Choosing the right diamond for your engagement ring involves considering the 4Cs: Cut, Color, Clarity, and Carat weight. Here are some tips to help you:

Cut: The cut of a diamond refers to how well it has been shaped and faceted. It affects the diamond's brilliance and sparkle. Look for a diamond with an excellent or very good cut grade to maximize its beauty.

Color: Diamonds are graded on a color scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the higher the grade and value. Typically, diamonds in the near-colorless range (G to J) appear white to the naked eye while still offering good value.

Clarity: Clarity refers to the presence of any internal or external flaws or inclusions in a diamond. Diamonds are graded on a scale from Flawless (no inclusions) to Included (visible inclusions). Look for a diamond with a clarity grade of SI1 (slightly included) or higher, as these inclusions are usually not visible to the naked eye.

Carat weight: Carat weight refers to the size of the diamond. Consider your budget and personal preferences when selecting the carat weight. Remember that a well-cut diamond can appear larger than a poorly cut one of the same carat weight. Additionally, consider your budget and the style of the ring you desire. Balancing the 4Cs while staying within your budget is important. It's also helpful to see the diamonds in person to observe their beauty and characteristics. Visit reputable jewelers and ask questions to ensure you make an informed decision.

Ultimately, choose a diamond that speaks to you and matches your partner's taste and style.

Can I upgrade my diamond in the future?

Yes. Each earth-created diamond can be traded in for a 100% credit towards a brand-new earth-created stone that costs at least twice as much. Any lab-created diamond may also be traded in for 100% credit towards a brand-new diamond worth at least twice as much as the old one. The improved diamond must be in its original state and come with the original laboratory grading report. For a little fee, Nivetta may also modify most rings to fit the additional diamond.

Can I request specific diamond characteristics or specifications?

Our product settings allow you to customize and select the diamond Carat weight, diamond clarity, and diamond color directly on the product page.

How do I ensure the diamond is genuine and not a fake?

You can always have a 3rd party verify your purchase as well by sending if off to a reputable lab such as GIA, AGS, IGI. Keep in mind small variances in opinion may exisist as grading is soley based on a professional opinion of those graders. Please note clarity enhanced diamonds are not graded by GIA.

Is a lab created diamond better than an earth created diamond?

Whether a lab-created diamond is better than an earth-created diamond depends on personal preferences and specific considerations. Here are some factors to consider when comparing lab-created and earth-created diamonds:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Cost: Lab-created diamonds are often priced lower than comparable earth-created diamonds. This is because the production process of lab-created diamonds is more controlled and predictable. If budget is a concern, lab-created diamonds can provide a larger or higher-quality diamond for the same price as an earth-created diamond.

Physical Properties: Both lab-created and earth-created diamonds have the same physical, chemical, and optical properties. They are composed of carbon atoms arranged in a crystal lattice structure. In terms of brilliance, sparkle, and durability, there is no significant difference between the two. 

Ultimately, the choice between lab-created and earth-created diamonds depends on personal preferences, ethical considerations, budget, and the significance one places on the natural origin of diamonds. It's important to consider all these factors and make an informed decision based on your individual values and priorities.

Where do lab grown diamonds come from?

Lab-grown diamonds, also known as synthetic or man-made diamonds, are created in specialized laboratories using advanced technology and processes that simulate the conditions necessary for diamond formation. These laboratories use one of two main methods to grow diamonds:

Chemical Vapor Deposition (CVD): In the CVD method, a small diamond seed is placed in a controlled environment with a carbon-rich gas. Through a chemical reaction, the carbon atoms are deposited onto the seed, layer by layer, gradually growing a larger diamond.

High-Pressure High-Temperature (HPHT): In the HPHT method, a small diamond seed is placed in a press that subjects it to extremely high pressure and temperature. Carbon source material is also present, which dissolves and re-crystallizes around the seed, resulting in the growth of a larger diamond.

 

Both methods require specialized equipment, precise control of temperature and pressure, and a carefully controlled environment to ensure the growth of high-quality diamonds.

It's important to note that lab-grown diamonds are not imitations or simulants. They have the same physical, chemical, and optical properties as natural diamonds. The main difference is their origin: lab-grown diamonds are created in a laboratory, while natural diamonds are formed deep within the Earth's mantle over millions of years.

Lab-grown diamonds offer an alternative to natural diamonds and are recognized as legitimate and genuine diamonds. They are becoming increasingly popular due to their ethical sourcing, environmental sustainability, and often more affordable pricing compared to their natural counterparts.

Can you see a difference between a lab grown diamond and a earth mined diamond?

To the naked eye, it is generally very difficult to distinguish between a lab-grown diamond and an earth-mined diamond based solely on their appearance. Lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds, as they are composed of carbon atoms arranged in a crystal lattice structure.

Can you see a difference between a lab grown diamond and a earth mined diamond?

No, not even by the naked eye not even the most highly trained professional would know the difference even with a loupe.
