Hyalite Opal (Opal-AN) ("Blood Vessel Opal") cat’s eye A very small nick on

A very small nick on the top of the piece is the only spot of damage that I can see on the display side (the piece is incomplete on the back where it detached from the pocket wall)

Some of these "fingers" are broken and show a radial growth pattern in the center

and a bit of character

so it's a big deal when you find crystals like this which are so unblemished and bright

Hyalite Opal (Opal-AN) ("Blood Vessel Opal") cat’s eye A very small nick onThis "Round Brilliant" cut Hyalite Opal gem is translucent with a golden to orange to colorless interior, but the most important aspect of the piece is the fact that it shows tiny red capillary like inclusions of iron oxide just below the surface, which has given this material the nickname "Blood Vessel Opal". If you look closely, you can see the tiny fibrous inclusions that have an almost organic appearance. This is truly unique and interesting Opal
