O is for Opals... they're my birthstone, since I was born in October.
Opals are hard to photograph... at least mine are. Here are some attempts, before I resort to professional pictures:
This bracelet was my present to myself ... I bought it while shopping for my wedding band (which doesn't have any opals in it)
These are wonderful translucent opals that catch the light and play with it. They're not milky or fiery -- but you can see the lights from those types in them anyway.
This is a necklace that my DH gave me for my anniversary last year:
It is probably the "milkiest" opal I own ... but it's still pretty fiery. It came from my favorite jeweler of all time: Christopher Jupp as did this one, which is the only one of this pendant to hold an opal (he usually puts faceted stones in it)
Anyway, I also have some unpolished opals in a pendant, that refuse to be photographed. And I'm still hunting for a professional picture that is similar. While looking however, I DID find a link to a kit for the Bolder Opal Jacket see, even googling rocks will get you knitting!
But opals aren't just for jewelry.... see
Let's look closer at that ornament just above the quillian...
Yep ... that's an opal
and there's another one on the other side too... it almost matches!
