Yes the blue agate pair in your photos, the top is also gorgeous with or with the drops, or you can pair the drops with another top, very versatile.

Magnificent brooch, great choice Red.
I was window shopping Leibish last week and there were these beautiful earrings by Paula Crevoshay. If I win lotto I'll be back for them.
Great photos! You're great at choosing Tahitian pearls they're always very colourful. Did you look at other types of gemstones as well while you're at the show?
