I have a strand of Sea of Cortez pearls that were made for me about 15 years ago. It was made with a hand made 18k disc in between each pearl instead of knots. The clasp is also handmade of 18k gold. I need to have these appraised thinking about selling them. Care Ehret was the designer but I'm not sure if she is still around. The strand has 39 baroque pearls and is about 18 inches long. I took some pics if anyone has any information about how to identify them. They do illuminate red under UV light but hard to capture with an I phone camera. Thanks in advance, Debbie
