About Gemtastic Jewelry

Gemtastic Jewelry is an independent fine-jewelry studio led by master jeweler J.R., based in Brooklyn Park, Minnesota. We design and build elite, high-end custom jewelry entirely in-house — from luxury bridal and statement pieces to custom grills and hip-hop pendants.

Every piece starts as a 3D CAD model, is printed at high resolution on our Anycubic Photon Mono M3 Plus resin printer, burned out in a Paragon SC2 kiln, and cast in solid gold by lost-wax investment casting — then hand-finished and stone-set at the bench. No outsourcing, no mass production: real diamonds, solid 10K–18K gold, and craftsmanship you can trace from sketch to setting.
