[QUOTE="Martyz, post: 653210, member: 14320"] Hi Debbie, Great carving you’ve done there. It’s looks like the material polished well and held together which is a good sign. A couple of things to look for if it’s Ethiopian are: Was it comparatively inexpensive? (Because it looks like a fair chunk) Does slowly go clear and loose colour when Wet? Was it difficult to get a good polish and did it stay a bit grainy after polish? Has it cracked at all after polishing and allowing to dry completely? These can be indicators of hydrophane opal from Ethiopia. I’m no expert on Ethiopian opal but these seem like common issues with a lot, but not all of their opal. [/QUOTE]
