These translucent common opal mined from Tirtomoyo, Wonogiri, Java, Indonesia. I have problem with these Wonogiri opal classification for example like fire opal, jelly opal, prase opal, chrysopal or others. For example prase opal for deep green common opal, chrysopal nickel rich chrysoprase-like opal, fire opal for yellow-orange-red common opal... which labels are suitable for my Wonogiri opal?

I don't know how I would classify these either:

Perhaps they need their own name: Wonogiri Common Opal.

Honey opal would be fits with the Javanese common opal EXCEPT the greenish blue gray opalescent with honey color base.
