We see clients by appointment only. We take appointments for afternoons 12 to 4 PM in one hour blocks Tuesday through Sat. (In exceptional circumstances we can provide appointment times for your convenience). We will examine your jewelry while you wait which should normally take about an hour to an hour and a half. Some appraisers will do it in about 15 minutes, but we like to be thorough and make sure we have the best description of your jewelry. If you have multiple items you may need to leave them. We are insured to protect your jewelry. For security reasons we do not publish our address or take walk-ins. We will provide our address when you make the appointment.

We can accept items via Registered Mail US Postal Service. Please insure for the value you believe they may be worth. Do not put anything on the package that might indicate it contains gems or jewelry. Contact us for the shipping address, do not use the Lonestar Gem Lab address. When you contact us we will email you a form to fill out and include with the shipment. We video the opening of packages and the preparation of packages before we ship back to you. We are not responsible for anything you ship to us until we open the package and have veified the condition.
