@Roberta,
Good on the getting work, anyway...
Cleavage go bragh, as they never say in ireland..
blue topaz.. at some point many years ago I lost the light blue green stone in my mother's platinum engagement ring (1935). Lots of stuff wrong with that ring, but I like it, and besides, it was hers. I eventually had a blue topaz put in it.. and wear it once in a while.
