Offices & Equipment

Welcome to our Accredited Gemological Laboratories!


We want you to be with us when we perform your appraisal service or consultation. Many clients do send items to us — but you are lucky if you are close by.  One client drove ten hours to use our services!  This is an environment developed to share information and to help the consumer understand the markets and jewelry in a totally honest and forthright manner.

We are here to answer your nagging questions. When shopping for an appraiser you may want to inquire about equipment and qualifications. The diamond color comparison set we use had to pass through AGS to be approved as a Master Set.

A number of appraisers use CZ master comparison sets.  These can change color over time and comparing CZ’s to diamonds is not comparing apples to apples.  We encourage you to look through our microscope at your item, so you can understand why we are grading the way we are.
