Conscientious and Meticulous
Richard and I met several years ago through the E.T. Gem & Mineral Society. We are both GIA gemologists. Over the past few years we have met at the Society meetings and I have come to know Richard through our shared appreciation of gems and minerals. Richard is constantly learning the latest info about the appraisal of gems and jewelry. You won't find a more honest and conscientious person for appraising your jewelry.

Thorough and Detailed Appraisal Report
Mr. Armstrong provided very thorough and detailed insurance appraisal reports for two pieces of jewelry I received as gifts from family. I'm so glad I found Lonestar because both pieces have increased significantly in value since their last appraisal and I want to be adequately insured. The reports were informative, detailed and thorough, and in the case of one of the pieces (a mid-century charm bracelet) quite fascinating. I really enjoyed learning so much about this piece. No detail goes un-researched!
Expertise / Items Examined: Mid-century charm bracelet and diamond fashion ring
Professional and Detail Oriented
Mr. Armstrong was professional and completed the appraisal in the time frame promised. The gem and jewelry valuation report was a 20 page certified document with great attention to detail. I was pleased with the presentation of the report and should I need another piece of jewelry appraised, I will certainly use him again. Wonderful overall experience.
Expertise / Items Examined: Crown of Light; Couture Collection bracelet. Valued over 40k
I highly recommend this company for any appraisal purpose. The report is detailed, and specially tailored to the requested purpose. Mr. Armstrong is certainly most knowledgeable, and he is clearly willing to go out of his way to maximize the accuracy of his report.

Great Guy. Very Good Appraiser
Mr. Armstrong is a very good Gemologist and Appraiser. He knows his gemstones and has a passion for his work. He is very reasonable on his price. He also has all the equipment needed to identify gemstones and to see if they have been treated.
He takes the time to do the job right and he is very knowledgable.
Very Thorough Ring Insurance Appraisal
Richard is great to work with and pays attention to details. His report is extremely comprehensive and written at a technical level for the non-experts to comprehend. His communication throughout the entire process was impeccable and would definitely use his services again. Thanks Richard for the honest appraisal on my diamond engagement ring!
