I got these from a friend years ago and have always wondered what kind of pearls they were. She got them from a jewelry store called Stanley in Little Rock, AR. The clasp says 14kg.
By the way, there is another P-G member named KarinK so it may be easy to mix you two up.
(Just a heads up to us all to pay attention so we know who we are addressing.)
The avatar may help. Also location.
Maybe even making a small modification in your username, OP?
Four or five years ago a member joined P-G with a username nearly identical to mine and it got confusing. She and I both made minor changes to distinguish ourselves.
