This means these diamonds remain unpolished and uncut even when they are put on sale.
Identifying a rough uncut diamond ring is quite easy. Rough diamonds look like transparent stones that can either be colorless or have a tinted brownish or yellow color. However, most rough uncut diamonds are tinted, and hence, the colorless stones are more valuable. You can identify raw diamonds by testing them using a portable diamond tester that works by passing electricity through the stone for detecting its electrical conductivity.
Some jewelry shops offer rough uncut diamond ring or other uncut diamond jewelry. You can either buy these as loose diamonds or else as mounted ones. If you are thinking why you even need to buy these unpolished and uncut stones, it will be good to note that these stones are very cheaper than polished and cut diamonds. This is because cutting and polishing incur additional cost that results in a huge difference in the price. Besides, it will always be cool to wear something unique.
