Client Reviews

Take a look and see what our clients are saying about our gem & jewelry appraisal services.

Jen at La Jolla Gem Appraisal was fast and professional. I needed a Rolex appraised during their busiest time of the year (holiday season). She also connected me with a quality buyer as I wanted to sell my watch. I won't hesitate to use her services again in the future. Whether you need appraisal for insurance reasons or estimating an items value and authenticity this place has you covered!

I highly recommend Jen and La Jolla Gem Appraisal. I scheduled an appointment and watched while Jen studied and evaluated my ring. As promised a formal written appraisal, that I can use for insurance purposes, was emailed to me two weeks later. Jen is very knowledgeable and tells you what she is doing as you watch her evaluate your jewelry. I trust Jen's knowledge and handling of precious items.
