What is a single crystal tool? Differences and connections between ND/MCD/CVD/PCD tools

Do lab-grown diamonds have color grades? Will lab-grown diamonds turn yellow?一. Are there color grades for lab-grown diamonds?The most common color of lab-grown diamonds is colorless and transparent. However, if you look closely, some lab-grown diamonds are actually slightly yellowish in color. Ther

一． What materials are synthetic diamonds made of?Synthetic diamonds are polycrystalline diamonds made from the aggregation of diamond crystals with a diameter of 10 to 30 nanometers. The manufacturing process is similar to the process by which diamonds form naturally.There are two main types of mate

What is CVD diamond? The difference between CVD grown diamonds and natural diamonds

The new star of semiconductor materials: CVD diamond

CVD diamond, short for Chemical Vapor Deposition diamond, is a synthetic diamond produced using a specific growth process. Unlike natural diamonds, which are formed deep within the Earth over millions of years, CVD diamonds are created in a controlled laboratory environment.

In June, foreign media reported that the diamond price index has fallen by 6.5% this year, and is even 18% lower than its historical high in February 2022. Diamond prices are continuing to plummet, and it is expected that diamond prices will continue to decline in the future until everyone's percept

There are two main methods for producing lab diamonds: high temperature and high pressure (HPHT) and chemical vapor deposition (CVD).
The most common method in China is still the high temperature and high pressure method, and the process is relatively mature,

Although lab diamonds have only entered the public eye in recent years, they have a long history. Suppliers said: "Lab diamonds are basically in short supply now, mainly because they have become popular since the second half of last year. Due to several major events, one It is the country's larges

After years of dormancy, lab diamonds ushered in an explosion driven by multiple benefits. The latest data in 2021 shows that India's lab diamond imports and exports have reached a record high, and the industry is booming. The two technical routes of HPHT and CVD have their own merits, and the indus
