"2024 sees 5% drop in U.S. engagement ring spending, with lab-grown diamonds now over 50% of center stones. Average carat size rises to 1.7 as couples prioritize value. Explore trends in designs, metals, and the natural vs lab-grown diamond divide."

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

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

Diamond is a major participant in the revolution of quantum materials and quantum technology. In addition to diamond quantum computers, there are many applications. For example, GPS diamond magnetometers that use NV color centers to measure magnetic fields, and NV color center diamonds to enhance ma
