Black opal

[The governor]

I posted about this opal many years ago but never put up a pic cause it went missing. Today it reappeared I’m wondering if it’s worth getting mounted on a ring??? It’s 15mm long 10mm wide 5mm thick, bottom right
Pic is of the back

Not quiet the best contrasting colours inside of it .
But still a niece piece .
