Merlinite (a trade name) is a form of common Opal, it's known as Dendritic Agate and Dendritic Opal. The black dendritics on the beautiful white opal makes outstanding looking jewelry. I purchased my rough from a dealer in Tucson during the gem sale in 2014, he said it came from Australia.

Western Australia hosts many deposits of common opal. Most of them occur in the Eastern Goldfields area near the towns of Leonora, Kalgoorlie & Norseman.

Approx size: 25 x 26.5 x 4.5 mm, Weight: 34.5 ct

A lot of effort went into giving you a product that will make it easier for you to finish, or keep it as a nice looking natural specimen and display it on the free plastic stand. The stand is included so it will help make the slab stand out in your specimen cabinet or on a shelf.

Contact us if you have any special requests, for a small charge we will re-shape or cut special slabs to your specifications.

Use my pictures with the 10 x 10 mm background squares and the 18 mm dime to help with size visualization. All pictures are taken dry.

I try to eliminate all the pits and open fracture and I smooth all sides. In the descriptions I will note anything I couldn't remove. Your getting a slab that is easy to finish and no waste to deal with. If you want to finish the slab(s) I have posted some guidelines on my website blog
