I'm not sure if this will be considered since you can already make a base out of the rough opal - but the opal base feels a little bland to me so I thought I'd make a base that looks more like this cool little image we get:





A clear image of the base



An image of the structure of the base - without lines and with colour blotches



And a quick, simple but pretty design I threw together with some markings

If people actually like it but it wouldn't be added because of the opal base, perhaps it could be named something different and not be connected to the gem at all? Maybe a combo base including opal itself? I'm not entirely sure, but I thought I'd still suggest it even if just for fun

(By the way, if anyone has an idea of what genetics group it could belong to please share your knowledge)
