About Lab Grown Diamonds

Are lab grown diamonds real diamonds?

Yes, lab grown diamonds are 100% real diamonds. They have the exact same chemical composition (pure carbon), crystal structure, optical properties, and physical characteristics as natural diamonds. The only difference is their origin – lab grown diamonds are created in controlled laboratory environments rather than mined from the earth. Both the Federal Trade Commission (FTC) and gemological institutions like GIA and IGI recognize lab grown diamonds as real diamonds. Every diamond in our engagement ring collection is a genuine diamond.

How are lab grown diamonds made?

Lab grown diamonds are created using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). The HPHT method replicates the natural conditions deep within the Earth by subjecting carbon to extreme pressure (1.5 million pounds per square inch) and temperature (2,700°F). The CVD method places a diamond seed in a chamber filled with carbon-rich gases, which are then heated to create plasma that deposits carbon atoms onto the seed, growing a diamond layer by layer. Both methods produce genuine diamonds identical to mined ones.

What is the difference between lab grown diamonds and natural diamonds?

The only difference between lab grown diamonds and natural diamonds is their origin. Lab grown diamonds are created in laboratories over weeks, while natural diamonds form deep in the Earth's mantle over billions of years. Chemically, physically, and optically, they are identical – same hardness (10 on Mohs scale), same brilliance, same fire, and same durability. Even expert gemologists cannot distinguish between them without specialized equipment. Lab grown diamonds simply offer an ethical, sustainable, and more affordable alternative.

Are lab grown diamonds the same as cubic zirconia or moissanite?

No, lab grown diamonds are completely different from cubic zirconia and moissanite. Cubic zirconia is a synthetic material (zirconium dioxide) that merely resembles diamonds but has different properties – it's softer, less brilliant, and less durable. Moissanite is silicon carbide, which has different optical properties (more rainbow sparkle) and a different hardness. Lab grown diamonds are actual diamonds with the same carbon composition and properties as mined diamonds. They should never be confused with diamond simulants.

Can you tell the difference between a lab grown diamond and a natural diamond?

To the naked eye, even trained jewelers cannot distinguish between lab grown and natural diamonds. They look absolutely identical because they ARE identical in every physical and optical property. The only way to tell them apart is with specialized laboratory equipment that can detect subtle differences in trace elements and growth patterns. All our lab grown diamonds are laser-inscribed on the girdle indicating they are laboratory grown, ensuring complete transparency.

Quality & Certification

Are lab grown diamonds certified?

Yes, all quality lab grown diamonds are certified by reputable gemological laboratories. At Elista Jewel, our diamonds are certified by the International Gemological Institute (IGI) or GIA (Gemological Institute of America). These certificates grade the diamond's 4Cs – Cut, Color, Clarity, and Carat weight – using the same standards applied to natural diamonds. Each certificate includes a unique identification number that is laser-inscribed on the diamond for verification.

What are the 4Cs of lab grown diamonds?

The 4Cs apply equally to lab grown diamonds:

• CUT determines how well the diamond reflects light and creates sparkle – this is the most important factor for brilliance.
• COLOR grades the absence of color on a scale from D (colorless) to Z.
• CLARITY measures the presence of inclusions or blemishes, from Flawless to Included.
• CARAT refers to the diamond's weight (1 carat = 0.2 grams).

Our engagement rings feature diamonds with excellent cut grades, DEF color range, and VVS - VS clarity for optimal beauty and value.

What clarity and color should I choose for my lab grown diamond?

For the best balance of quality and value, we recommend DEF color and VVS-VS clarity. G-H color diamonds appear white to the naked eye while offering significant savings over D-E-F grades. VS1-VS2 clarity means inclusions are not visible without 10x magnification, giving you an "eye-clean" diamond. However, if budget allows, D-F color and VVS clarity offer the highest grades. The most important factor is cut quality – always prioritize an excellent or ideal cut for maximum sparkle.

Are lab grown diamonds as durable as natural diamonds?

Yes, lab grown diamonds are equally durable because they have identical physical properties. Both score 10 on the Mohs hardness scale, making them the hardest known natural material. Lab grown diamonds will not chip, scratch, or fade over time. They are perfect for everyday wear in engagement rings and can be passed down through generations just like natural diamonds. Our lifetime warranty covers all our lab grown diamond jewelry.

Do lab grown diamonds lose their sparkle over time?

No, lab grown diamonds maintain their brilliance and sparkle forever, just like natural diamonds. They don't cloud, fade, or change color over time. Regular cleaning will keep your diamond looking its best by removing oils and dirt that can temporarily diminish sparkle. We recommend cleaning your jewelry every few weeks with mild soap and warm water, or bringing it to us for professional cleaning – a complimentary service for all Elista Jewel customers.

Pricing & Value

How much cheaper are lab grown diamonds compared to natural diamonds?

Lab grown diamonds typically cost 60-80% less than comparable natural diamonds. For example, a 1-carat natural diamond engagement ring might cost $5,000-8,000, while a similar lab grown diamond ring could cost $1,500-3,000. This significant price difference allows you to either save money or get a larger, higher-quality diamond for the same budget. At Elista Jewel, our lab grown diamond engagement rings start at just $499, making beautiful diamond jewelry accessible to everyone.

Why are lab grown diamonds less expensive?

Lab grown diamonds cost less because the production process is more efficient and doesn't involve mining operations. Natural diamonds require expensive mining operations, longer supply chains, and billions of years to form. Lab grown diamonds can be produced in weeks with predictable costs. The lower price doesn't reflect lower quality – it reflects more efficient production. You're getting the same diamond for less, not a lesser diamond.

Do lab grown diamonds have resale value?

Like natural diamonds, lab grown diamonds have resale value, though the market is still developing. We recommend purchasing diamond jewelry for its sentimental value and beauty rather than as a financial investment. Natural diamonds also typically resell for 20-50% of retail price. The advantage of lab grown diamonds is you can invest the savings into a larger stone or higher quality setting while enjoying the same lifetime of beauty.

Can lab grown diamonds be insured?

Yes, lab grown diamonds can be insured just like natural diamonds. Most insurance companies, including major providers like Jewelers Mutual, offer coverage for lab grown diamond jewelry. The process, policy terms, and costs are identical to insuring natural diamonds. We provide all necessary documentation, including IGI/GIA certificates and appraisals, to help you secure insurance coverage for your purchase.

Ethics & Sustainability

Are lab grown diamonds ethical and conflict-free?

Yes, lab grown diamonds are 100% conflict-free and ethically sourced. Unlike mined diamonds, which have been linked to human rights abuses and conflict financing in some regions, lab grown diamonds are created in controlled laboratory environments with full traceability. There's no risk of supporting unethical mining practices or "blood diamonds." For socially conscious consumers, lab grown diamonds offer peace of mind that your symbol of love doesn't come at someone else's expense.

Are lab grown diamonds better for the environment?

Lab grown diamonds have significantly less environmental impact than mined diamonds. Diamond mining requires moving tons of earth, disrupts ecosystems, creates large open pits, and produces substantial carbon emissions. Lab grown diamond production, while energy-intensive, uses no land displacement, produces minimal waste, and many facilities use renewable energy. Studies suggest lab grown diamonds have up to 7 times less environmental impact than mined diamonds.

Are lab grown diamonds sustainable?

Lab grown diamonds represent a more sustainable option for diamond jewelry. The production process doesn't deplete natural resources, displace communities, or damage ecosystems like mining operations. Many lab grown diamond producers are investing in renewable energy to further reduce their carbon footprint. At Elista Jewel, we partner with suppliers committed to sustainable practices, ensuring your purchase supports responsible diamond production.

Diamond Shapes & Styles

What diamond shapes are available in lab grown diamonds?

Lab grown diamonds are available in all the same shapes as natural diamonds:

• Round Brilliant – The most popular, offering maximum sparkle
• Oval – Elongated elegance, appears larger than its carat weight
• Emerald – Sophisticated step-cut with a hall-of-mirrors effect

Each shape has its own personality and appeal – browse our collections to find your perfect match.

Which diamond shape looks the biggest?

Elongated shapes like Oval, Marquise, and Pear tend to look larger than their carat weight suggests because they have more surface area on the top (table). An oval diamond can appear 10-15% larger than a round diamond of the same carat weight. Marquise cuts offer the largest face-up appearance of all shapes. If maximizing perceived size is important, consider these elongated shapes for your engagement ring.

What are the most popular engagement ring styles?

The most popular engagement ring styles include:

• Solitaire – Timeless single-stone simplicity
• Halo – Center stone surrounded by smaller diamonds for added sparkle
• Three Stone – Representing past, present, and future
• Pavé – Diamond-encrusted band
• Vintage & Art Deco – Intricate details and milgrain
• Toi Et Moi – Romantic two-stone design
• Bezel – Modern metal-wrapped setting
• Bridal Sets – Matched engagement ring and wedding band

At Elista Jewel, we offer all these styles and more, each available with various diamond shapes and metal options.

Do lab grown diamonds come in different colors?

Yes, lab grown diamonds are available in fancy colors including yellow, blue, pink, and green. These colored diamonds are created by introducing specific trace elements during the growth process – nitrogen creates yellow, boron creates blue. Fancy colored natural diamonds are extremely rare and expensive, but lab grown colored diamonds make these stunning hues accessible. Browse our collections to see available options.
