Matrix opal is popular for bold jewelry designs, especially rings and pendants. Its natural backing offers durability while showcasing organic patterns that make every piece one of a kind.

Australian Matrix Opal

Most matrix opal comes from Australia, particularly Queensland. These stones are valued for their stable structure and naturally distributed play-of-color.

Matrix Opal Cabochons

Matrix opal is commonly cut as cabochons to highlight its natural patterns. Smooth domed cuts enhance color contrast and are ideal for handcrafted jewelry.

Loose Matrix Opal for Collectors

My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
