HRD Antwerp has graded the first wearable ring made completely of lab-grown diamond,it claims.

　　Synthetics producer Dutch Diamond Technologies(DD)created the 3.87-carat,E-color,VVS2-clarity piece from a 155-carat rough chemical vapor deposition(CVD)lab-grown-diamond plate.The company made the ring,called“Project D,”to mark its 10th anniversary.It took a year to manufacture,and has 133 facets.

　　“We wanted to create something stunning that would highlight our innovative and high-tech techniques,”Ton Janssen,CEO of DD,said last week.“I think we’ve more than succeeded with the one-off‘Project D’ring.”

　　The piece is not the first all-diamond ring.In 2011,Swiss jeweler Shawish revealed a ring made from a single crystal of natural diamond.Additionally,in December,Sotheby’s auctioned an all-diamond ring made from a single lab-grown stone.The piece,created by Apple chief design officer Sir JonyIve and industrial designer Mark Newson for Diamond Foundry,sold for$256,250,but is still in production,Diamond Foundry said,as it’s making it to fit the buyer’s finger.

　　With the improvement of CVD synthesis technology,through the adoption of gas raw material(hydrogen,methane),we get the completely transparent and colorless large size diamond single crystal under less than one air pressure,the temperature of 800-1200℃by epitaxial growth way,its composition,hardness,density,etc.are basically identical with natural diamond,but the price is much lower than that of natural diamond;different from the method of high temperature and high pressure(HTHP),CVD artificial synthetic technique does not need to use the catalyst,and puts an end to forming metal inclusions,cracks,holes,etc.in the production.

　　Features:after polishing,the clarity is commonly VVS and above level,color chromaticity of D-J.

　　We can provide raw diamond at carat level.
