Thank you CathyKeshi, Pearl Dreams, newberry and Katbran.
We looked at the new spinel against my brooch from the back, and the colors looked to be a perfect match. I think my new Tahitian drop will look very sweet.
Also, the jeweler now has several new Crevoshay pieces on display. Nearly all of them allow you to remove the drops from the tops. Paula has a number of pieces with dolphins carved into the backs of the jewels. There was also a pair of carved icy jade earrings which were amazing. (Now I know where Icy Jade got her name.) One brooch that I loved had a top part set with a huge faceted moonstone and a 0.5 ct pink tear drop spinel. Hanging from that was a pink Peruvian opal drop that must have been about three inches long and was decorated with Paula's distinctive gold swirls and studded with tiny pink spinel. This huge drop would look stunning hanging from my brooch. I loved the top moonstone piece as well. Paula's pieces interchange beautifully. There were also some rings, and they fit me perfectly. So fun to try on. I guess Paula makes her rings in my size.
