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.

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.
