Custom Base Making
Our custom base-making lab can make lucite bases for your fine mineral specimens to ensure that your favorite pieces are safely and aesthetically displayed. Each base is custom-made to fit your specimens in our fully-equipped lab without requiring glue, sticky tac, or other adhesives to mount specimens upright.
We offer a wide variety of sizes that will accommodate most specimens, and engrave and mill each base specific for each specimen to ensure a perfect fit. For additional information regarding custom bases, including pricing, please visit our custom lucite base page. Additionally, you can reach out via the form below, or if you would like to include a custom base with your specimen order, simply check the box for custom base on your order form!
Please note: We do not appraise specimens based on photos or videos sent to us online, and we do not operate an identification lab. On a very limited basis, we will appraise specimens for a fee that we are able to see and hold in person.
