We are now seeing many lab-created diamonds hitting the market that don’t measure up. We grow our diamonds in the world’s most technologically advanced laboratories using innovative growth methods, a slower growth cycle, and renewable energy sources, making our diamonds the best for both the environment and quality. Cheap lab diamonds are simply not worth your time or money— they're more brittle, post-treated to mimic clarity, and manufactured in facilities with questionable human rights and environmental practices.
What are the best lab grown diamonds?
The best lab diamonds are high quality, sustainable, and backed by third-party verifications. There are many types of lab diamonds on the market that do not measure up in quality or ethics.
High Quality: Type lla diamond, grown using CVD technology and untouched by any post-treatment, finished with an exceptional cut.
Sustainability: Not all lab diamonds are sustainable. Make sure diamond is grown with renewable energy and or carbon-capturing resources and gives back to mining communities.
Are lab diamonds less sparkly?
Lab-grown diamonds, if grown slowly and are not post-treated, are as sparkly as their mined counterparts. Although all diamonds, whether lab or minded, share the same physical and chemical properties, some post-treatments can damage the internal structure of the diamond, causing them to be less sparkly. That is why it's paramount only to purchase high-quality lab-grown diamonds.
What are the quality grades of lab diamond?
Lab-grown diamonds are graded based on the same 4Cs and exhibit the same variations in color, clarity, and cut like their mined counterparts. However, Type lla diamonds from us contain such a pure form of carbon they will appear brighter than the regular Type Ia. The same color grades in a Type la mined or lab diamond will look duller than a Type lla diamond in the same color grades.
What is a high quality lab diamond?
Beyond sustainability, the highest quality lab diamond is a Type lla diamond grown using CVD technology and untouched by any post-treatment. This pioneering approach must be paired with an exacting cut to capture extraordinary light dispersion and sparkle—such diamonds merit evaluation against rigorous benchmarks like AGS or GCal 8x cut grading. At ZORÉ, this distinction is inherent, making our diamonds the highest quality – the top 1% of all diamonds.
