How is a Lab Diamond Grown?

Diamonds are lab created by recreating the conditions underneath the Earth that result in diamond growth: pressure, heat, & carbon. Today, there are two methods of growing diamond gemstones: High Pressure-High Temperature (HPHT) & Chemical Vapor Deposition (CVD). Each process is best suited for certain sizes & colors of diamonds. Learn more about growing diamonds. It takes 7-10 days to grow a 1 carat lab diamond, and about a month to grow a 3 carat diamond. If you try to grow a diamond any faster, the diamond crystal will fracture. Thus, there is a physical speed limit to how fast you can grow diamonds. Because diamonds are grown by recreating the conditions of nature, lab grown diamonds have the same variations of color and clarity that exist in natural diamonds (the 4 C's). While the average laboratory-grown diamond is better quality than the average mined diamond, lab diamonds still range across the color and clarity spectrum, just like mined diamonds.

Can a Jeweler Tell the Difference?

No, a jeweler cannot tell the difference between an Ada diamond and a natural diamond. Our man-made diamonds are indistinguishable from mined diamonds, even to an expert gemologist using traditional jeweler's tools. A CNBC reporter took an Ada Diamonds ring to multiple jewelers in the New York Diamond District (47th Street), and not one of the diamond purchasers could tell the diamond was man-made. There are lab diamonds in the market that contain obvious defects, such as color tinges and blurry material. These defects are present in cheaper lab diamonds and make them easier to differentiate from natural diamonds. Ada Diamonds screens all of our lab diamonds for these issues through our four-step quality control process. Rest assured that Ada’s diamonds rival some of the best natural diamonds in the world. Ada Diamonds is proud of the origin of our diamonds. We refuse to sell mined diamonds, as we believe lab diamonds are more sustainable, ethically superior, and an investment in the future. All of our diamonds above 0.50ct are microscopically laser inscribed by third party grading organizations with a unique ID number and the letters ‘LG’ to indicate the diamond is lab grown.

Are Lab Diamonds Less Expensive?

Much like mined diamonds, lab diamonds are priced based on their 4Cs characteristics. Lab diamonds are typically ~80% less expensive than natural diamonds of the same size and quality.

Why Should I Choose a Lab Diamond?

Known Ethical Origin: All the diamonds we offer are conflict free and in no way connected to the dubious diamond trade that continues to flourish to this day. Learn More. A Cleaner Purchase: The extraction of diamonds from the earth is fossil fuel intensive, environmentally damaging, and becoming less sustainable every year. Growing diamonds uses a fraction of that energy and does not contaminate fragile ecosystems in rivers and lakes. Superior Quality & Size: Ada’s clients typically are able to achieve a 50% larger carat weight in lab grown over a comparable mined diamond of the same quality. Want a diamond you can be proud of? Lab grown offers the ability to go from unexceptional to extraordinary, carat for carat, price for price.
