Downtown Los Angeles · Est. HMS MFG
HMS MFG is a custom jewelry manufacturer based in Downtown Los Angeles. We take 3D-designed pieces from STL file to finished metal — using the same lost-wax casting process as fine jewelry houses, at production speed.
Drop your 3D file directly on the platform. We parse geometry, verify watertightness, and calculate cast weight automatically.
Pricing is calculated from real-time gold and silver spot rates. No email threads, no waiting — you see your number instantly.
Wax print, invest, cast, finish. Your piece is made in our Downtown Los Angeles facility and shipped direct to you.
Gold pricing updates automatically from live XAU spot rates. Silver is fixed at our current caster rate. You see the real number — no inflated estimates, no surprises at invoice.
Our library offers a growing collection of ready-to-cast designs — rings, pendants, bangles, and chain sets — that you can order directly without uploading anything. Each file has been verified for printability and castability before it goes live.
