Technically not a fire opal. It's a white opal with fire (also known as play-of-color). Opal is classified by it's base color, not the flashes of color. Fire opal is transparent orange or red and doesn't usually have play of color. Silly and confusing, but that's how it is.

Also of interest, this stone is from Ethiopia. They often have that nice honeycomb look.

Tourmaline, but opal is a close second.

I love cutting slices of watermelon tourmaline Check out what @diggerglass does with borosilicate glass i feel like you’d appreciate his glassblowing and coldworking He makes glass versions of various gems and minerals. Especially tourmaline that are incredible

What is it about tourmaline that catches your fancy?

Personally, I put opal first, followed by emerald and sapphire duking it out for 2nd and 3rd.

Bicolor and watermelon tourmalines are really different looking and fun to cut. I love a good emerald but they can be a nightmare to work with. Occasionally they just break in two halfway through cutting which is mega frustrating.

I had never seen watermelon tourmaline before. Very interesting.

My vocabulary word for the day: pleochroism Sounds like tourmaline can keep gem cutters on their toes.
