Welcome to Hydray, buy HPHT/CVD laboratory grown diamonds
Lab diamonds do not fade or change color over time. Hydray Diamonds specializes in providing lab-made rough diamonds. Compared with the rough diamonds that are mined, the rough diamonds that we sustainably cultivate have fewer impurities and defects. This makes the diamonds polished by our products whiter, brighter and stronger than most mined ...
2020-4-20 · CVD Diamonds — The New Kid on the Block. CVD on the other hand—which stands for chemical vapor deposition—is the modern disruptor of lab grown diamond technology. With CVD, a thin slice of diamond seed (often produced through HPHT) is placed in a sealed chamber and heated to around 800 degrees Celsius.

Diamonds were first synthesized from graphite in the 1950s by the HPHT process. In the mid-1980s, the process was modified to create diamond film. Later, chemical vapor disposition (CVD) improved diamond film production. In the mid-1990s, diamond-like coatings (DLC) improved on CVD, requiring less temperature and less energy.
CVD diamonds are grown in a lab and are made from the element carbon, just as an Earth-formed diamond is. This is important to point out because some newcomers believe that lab grown diamonds are "synthetic", like cubic zirconium or moissanite loose stones. But that's not true. CVD diamonds have an edge when it comes to cutting and polishing.

CVD diamond with strain lines: 2.16ct G VS1 CVD diamond with strain lines: 1.72ct G VS1. In contrast, HPHT diamonds do not exhibit such strain lines. Note how much clearer a diamond without strain lines looks compared to the CVD examples above. HPHT diamond without strain lines: 1.56ct E VS1
2016-7-25 · The CVD diamond growth method requires a lower upfront equipment cost than HPHT but may require subsequent treatment to improve the color of the diamonds grown. What is a High-Pressure High-Temperature (HPHT) Diamond? HPHT stands for high pressure, high temperature and is one of the primary methods used to grow diamonds in a lab.
2021-1-21 · IGI will also include specific diamond types, such as type IIa for CVD or type II for HPHT, upon request. The institute is currently working on incorporating commentary for post-growth treatment of fancy-color lab-grown diamonds into its reports, it added. It expects to introduce this in the "near future." Image: The IGI lab-grown report.
