Frequently Asked Questions

Mined diamonds and lab-grown diamonds are identical -- chemically, physically, & optically. Only the origin is different! One is grown above ground, and the other is grown underground.
YES. Our lab grown diamonds are 100% diamond in every way. Simulants such as Cubic Zirconium, Moissanite and diamond-coated materials are in no way a diamond – the reason they cost much less. Online companies selling lab-created gems often misrepresent their product as a diamond. Ours are type IIa which are the rarest and most valued of all real diamonds. Less than 2% of the world's diamonds are Type IIa! Diamonds are categorized into four types: Type Ia, Type Ib, Type IIa, and Type IIb. Diamonds that are IIa contain no measurable amount of nitrogen in the crystal structure. This impurity is what imparts a tint to "would be" colorless diamonds.
The most important aspects of a lab grown diamond is that no eco-systems are being destroyed and no one is being killed to make a profit. Lab grown diamonds also cost less 30-50%+ less than mined diamonds -- so you save money while obtaining the most sparkly material on the planet. While a diamond certainly still holds value, times change and so do people's perception of what holds value. Experiences have become much more valued in modern society, so our customers think of all the amazing money they saved to put towards a honeymoon!
While physically and chemically identical to mined diamonds, the main difference is in the pricing. Large rough diamond miners claim that mined diamonds are rare. This claim places a controlled pricing onto mined diamonds. Lab grown diamonds are free of this price control and are more rare than mined diamonds! Bain & Company reports about 133 million carats are mined each year. So how rare are natural diamonds really?
Lab-grown diamonds are grown by 1 of 2 processes: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). With HPHT, the technicians place a diamond "seed" (a small portion of a diamond crystal) into a graphite box which then simulates nature by applying high amounts of heat and pressure at 1500° celsius , melting the graphite into pure carbon and thus, creating a larger diamond crystal. In the other process, Chemical Vapor Deposition (CVD), a material is deposited from a gas (usually a mixture of hydrogen and methane), onto a diamond plate. A chemical reaction then takes place, producing deposits that grow onto the diamond plate. These processes take on average a few weeks to grow a rough diamond crystal ready for cutting.
Since the 1950s! At first, they weren't gem quality to set into jewelry but were mostly used for industrial cutting, because diamond is so hard. It has taken decades to perfect the process to grow gem quality diamonds which meet natural diamonds in terms of desirability and size.
Typically, lab grown diamonds cost 30-50% less than mined diamonds but this savings increases as the rarity of a diamond increases in carat, color and clarity.
Absolutely! Our lab grown diamonds come with certificates from the International Gem Institute (IGI) or the Gem Certification and Assurance Lab (GCAL).Below is a link to an article showing that IGI and GIA are just as strict in their grading: GCAL is a more scientific certificate:
GIA's grading for lab grown diamonds is extremely general. For example, a lab grown diamond that is H color and VS1 clarity, would be graded as "near colorless" and "very slightly" included. We can't sell to our customers like this – we need a specific color and clarity grade for pricing and authenticity. However, each and every diamond we sell can be certified by GIA upon request.
We are experts in the lab grown field. We at VARNI take the time to evaluate numerous diamonds, choosing only the best lab-created gems for our customers. We also have incredible designs to set the diamonds into and offer custom designs at no additional charge.
Yes. Whether it is a lab grown or mined diamond, they are appraised in the same exact way – inflated for insurance purposes in case of market increases for replacement.
Absolutely! Insurance companies insure lab grown diamonds the same way they insure mined diamonds, gemstones, moissanite, gold, etc.
The same as a mined diamond in that you will be offered about 40-60% less than current market value of your diamond. Reason being, retailers can buy most anything at wholesale prices, so they need to purchase it for less to make it worth their while. If there is a need for you to sell your lab-created gems, we eliminate the need to sell it elsewhere. Inquire with us for more information.
Our lab grown diamonds can be upgraded at full value towards a replacement of at least 50% or greater value. Simply, send your diamond to us with its original Lab report and choose your new diamond, then pay the difference. In the event of market decline, your diamond will retain comparable retail value.
