Can anyone Identify this white gemstone?

[Northeast Ignite]

Can anyone identify the gemstone? I thought it was Moonstone. It is a pure milky white opaque. Is it a moonstone or opal or Chalcedony or any else. But it is not white coral as I have tested it. I have not seen any fracture or cleavage

Definitely not moonstone or opal. Could be Chalcedony type or possibly a manmade glass type material.
If you put a bright light behind it can you see any structural features ie colour zoning, imperfections?

It looks kind of waxy, perhaps some sort of Jade?

I thought some colourless white Opal potch might be an option.

Potch can be white, to grey, to black as well as having some golden or greenish body tones (stay away from the green/golden body tones as they tend to craze from what I've found).

Coober Pedy probably has the 'whitest' colourless potch I've seen. I've got some in my workshop, I'll take a photo and post later today if I can remember

@Bron357 here is a piece of Coober Pedy colourless Opal AKA white potch. Unfortunately there is none of the quintessential Opal colourplay inside this stone. It's just a cloudy, white rock.



I'm thinking about doing a thread in this forum explaining body tone in Opal, it seems to be something a lot of people get confused about including a lot of vendors I've met.
