1 carat diamond ring will be engraved 1.00ct 50 minutes, which is 0.50ct.
Generally, more than 95% diamonds on the market are made of 18K gold (generally engraved with the standard of AU750), which contains 75% gold and 25% other precious metals. The hardness is high enough, the luster is bright, the style is fashionable and novel, and there are three colors of K white, K yellow and the most popular rose gold, which are most suitable for setting gems.
In addition to 18k, there are two kinds of platinum 950 and 900, which are relatively common. Its English abbreviation is "PT", which means "PT950" and "PT900" will be carved. These two kinds of gold are higher and softer. In fact, there are 990 kinds of platinum, and the gold content of PT990 is the highest among platinum. Few manufacturers dare to use this metal for inlay, but it is not uncommon.
