From your file to finished metal — in days, not weeks
Upload Your FileThe Process
No middlemen, no guesswork. Upload your STL, receive an instant quote linked to live metal spot prices, and we handle everything else in our DTLA facility.
Drop your STL file — binary or ASCII. Our system parses geometry and calculates volume instantly. No account required to get a quote.
Metal weight, casting labor, and finishing — all calculated from your file. Prices update with live gold and silver spot rates.
Your file becomes a wax model. We invest, burnout, and cast in your chosen metal using traditional lost-wax process — jeweler-grade every time.
Cast, cleaned, and shipped. Fully insured nationwide delivery. Turnaround from 5–10 business days depending on metal and quantity.
What We Cast
Every quote is linked to live spot pricing so you always know exactly what you're paying for — metal cost plus casting labor, nothing hidden.
A typical sterling silver ring quotes from $100–$160. The same piece in 14k gold runs $750–$1,100 depending on size — prices update daily with gold markets.

What Designers Say
“I used to spend half my Monday emailing casting houses for quotes. Now I upload my STL, see the price in seconds, and move on to designing. HMS changed my entire production workflow.”
Sarah Chen
Jewelry Designer, Los Angeles
“The live metal pricing is what sold me. I can price my pieces for customers knowing exactly what my casting cost will be — down to the penny. No other casting house gives you that level of transparency.”
Marcus Rivera
Founder, Riviera Jewelry Co.
“Drove down to their DTLA spot to pick up a run of custom pendants. The detail on the castings was clean — exactly what the 3D model showed. Already sent them my next batch.”
