Product Description

Product Description

What is Lab grown diamond?

Lab Grown Diamond are diamonds manufactured in a laboratory, as opposed to diamonds mined from the Earth. The gemological and industrial uses of diamond have created a large demand for rough stones. This demand has been satisfied in large part by synthetic diamonds, which have been manufactured by various processes for more than half a century. However, in recent years it has become possible to produce gem-quality synthetic diamonds of significant size.

     

     

                                                                                                          
 

HPHT diamonds are a popular choice for use in fine jewelry, where they can be pairedwith various metals such as gold, platinum, and silver. These diamonds are readilyavailable at wholesale prices and are certified for purity and clarity, making them areliable choice for jewelry manufacturers who incorporate them into their designs.

Affordable pricing is a significant advantage of HPHT diamonds over natural stones.which can be quite expensive due to the lengthy mining process, supply chain, andmiddleman commissions involved. As HPHT diamonds come directly from the laboratorythey are an excellent choice for those seeking affordable diamond options.
