A Cut pattern is the surface of the rough. The size can be bigger than 70mm. It is the most popular pattern in the market.
B Cut pattern is the side of the rough. It shows vertical fire which represents the growth pattern. It is an unique feature of authentic "Lab-Grown" synthetic opal.
The crushed opal is widely used for inlay design, such as ring, furniture etc.
Bello Opal is the mainstream of opal inlay. The intense fire makes the opals shinny even when the opals are thin and small.
