Opal - Canadian green


I’m trying to find a similar type of opal to this green opal (Canadian) I’ve found. It ranges from transparent to opaque, small amounts have mossy inclusions. I’ve looked all over and the closest I’ve found is Prase opal but this is a darker green with no nickel. Elemental analysis has been conducted and it would appear the main inclusion causing the colour is strontium and rubidium.
