There are particular rings, which have magical powers. I take great delight in telling couples that their ring is very special, and it empowers the wearer to "get out of housework".
I also discuss pearl engagement rings, and suggest that I am happy to design a pearl ring, AND an engagement ring, designed to take the wear & tear of every day life, unless they are happy with the idea that the pearl may have to be replaced.
Olga, I will check my records at work, I think I bought the white pearl from one of our local suppliers called South Sea Pearls. I am very nervous to take for granted that all their stock is South Seas, and it does have a lovely glow, which now makes me suspect FW.
The pink pearl came from Brisbane, no idea on its provenance, but it has a mate made into a pendant, and both of them are quite a variety of colours from one end to the other. Photos to follow if you want, tomorrow.
