The diamond industry is undergoing a transformative shift, and we are at the forefront with our new collection of 5 carat, 6 carat, and 7 carat DEF lab grown HPHT loose diamonds. These magnificent colorless stones deliver the same breathtaking beauty as mined diamonds — at 60% to 70% lower cost — making sustainable luxury accessible to more jewelry brands and consumers worldwide.
A 5 carat DEF mined diamond can command prices exceeding USD 500,000 at retail. Our lab grown HPHT equivalents offer identical optical and physical properties at a fraction of that investment. The cost savings flow directly to jewelry manufacturers, retailers, and end consumers — without any compromise on quality, brilliance, or durability.
| Carat Weight | Mined DEF (Est.) | Lab Grown HPHT DEF | Savings |
|---|---|---|---|
| 5 Carat | $150,000–$500,000+ | $15,000–$50,000 | Up to 90% |
| 6 Carat | $250,000–$700,000+ | $25,000–$70,000 | Up to 90% |
| 7 Carat | $350,000–$1,000,000+ | $35,000–$90,000 | Up to 90% |
Consumer attitudes are shifting decisively. A 2024 MVI Marketing survey found that 70% of millennials and Gen Z buyers would consider lab grown diamonds for engagement rings, citing sustainability and value as key decision factors. Major retailers including Pandora, Brilliant Earth, and Helzberg Diamonds have expanded their lab grown collections significantly.
The HPHT method produces diamonds with superior color grades, particularly in the DEF range. Unlike CVD-grown stones which often require post-growth treatment to achieve colorless grades, HPHT diamonds naturally emerge as Type IIa — the purest diamond classification — with exceptional optical transparency and brilliance.
