Jennifer is FABULOUS

Jennifer just appraised a new piece of jewelry for me in such a timely and professional manner. This is not the first time I've used Jenny at Gemworld for appraisals. She is such a knowledgeable gemologist and is so personable. It's a no brainer that anytime I need something appraised - old or new - I will bring my pieces to Jenny. I've also referred her to several friends who have been very pleased with the process and with Jenny's expertise!

Expertise / Items Examined: A diamond lariat necklace made from my previous engagement ring.

Company Response:Thank you for your kind words! It is always a pleasure working with you and I hope to see you again soon.
