What we do?
We do believe that an ability to purchase gemstones far lower than retail prices opens the door for everyone to the diamond industry. We work hard to make luxury affordable to everyone. By having strong ties with our site holders, Ametheus Holdings Pvt Ltd has the advantage of consistent diamond supply at a reasonable price. You will not only receive top quality diamonds, but diamonds with the best cut, clarity and color from us.

We have network of diamond cutters and merchants. There, we see which diamonds are currently available at wholesale prices and collect certificates from grading labs like Gemology Institute of America (GIA) / International Gemological Institute (IGI) / HRD Antwerp (HRD) / The National Gemstone Testing Center (NGTC) / International Institute of Diamond Grading & Research (IIDGR).

Lab Grown CVD Diamond

CVD diamonds, or Chemical Vapor Deposition diamonds, are lab-grown diamonds created by depositing carbon atoms onto a diamond seed in a controlled environment. They are chemically, physically, and optically identical to natural diamonds, with the same hardness (10 on the Mohs scale), brilliance, and structure. The CVD process involves placing a diamond seed in a vacuum chamber filled with carbon-rich gases (like methane and hydrogen), heated to around 800–1200°C, where the gases ionize, and carbon atoms layer onto the seed, forming a diamond over weeks.

Key Points:

  • Advantages: More affordable (30–40% less than natural diamonds), ethical (no mining), eco-friendly, and customizable in size and quality. They often achieve high purity (Type IIa, rare in nature).
  • Flaws: Like natural diamonds, they can have inclusions or color tints (e.g., brown), though these can be minimized or treated.
  • Comparison to HPHT: CVD uses lower pressure and temperature than the High-Pressure High-Temperature (HPHT) method, offering better control over clarity but sometimes lower quality than HPHT diamonds.
  • Grading: Certified by GIA or IGI using the 4Cs (cut, color, clarity, carat), with origin noted. They’re indistinguishable from natural diamonds without specialized equipment.
  • Applications: Beyond jewelry, CVD diamonds are used in electronics (e.g., power transistors) and thermal management due to their conductivity and heat resistance.

CVD diamonds are increasingly popular for engagement rings and luxury jewelry due to their sustainability and cost-effectiveness, with no visual difference from mined diamonds. If you’re considering purchasing one or want details on specific uses, let us know at [email protected]
