Real Gold. Real Diamonds. Los Angeles.
STF DIAMONDS is a working jewelry house in the Los Angeles Jewelry District — solid 10K and 14K gold at the prices plated brands charge.
Solid Gold Only
Every piece we sell is solid 10K or 14K gold. No plating, no brass cores, nothing that turns.
Jewelry District Direct
We make and source in the heart of the LA Jewelry District, so you pay workshop prices — not mall markups.
A Concierge, Not a Call Center
Text, call, or walk in. A real jeweler answers, remembers your name, and stays with your piece from idea to handoff.
How Every Piece Gets Made
Design & CAD
Your piece starts as a precise 3D model, adjusted with you until every line is right.
Casting
Solid 10K or 14K gold, cast in the Los Angeles Jewelry District.
Hand-Set Stones
Each diamond is seated and secured by hand under magnification.
Final Polish
Finished, inspected, and steamed to a mirror shine before it leaves the bench.
Downtown, On Purpose
Our showroom sits where Los Angeles buys its gold — the Jewelry District. Come in, try pieces on, and talk to the people who actually make them. No appointment needed for a look around.
Plan Your Visit
If You Can Describe It, We Can Build It
From engagement rings to script nameplates, custom work is the heart of the house. Bring a photo, a sketch, or just an idea — a jeweler takes it from there.

Frequently Asked Questions
Is everything really solid gold?
Yes. Every piece in the store is solid 10K or 14K gold — never plated, never filled. That is the whole point of STF DIAMONDS.
Will my piece tarnish?
Solid gold does not tarnish the way plated jewelry does. Wear it daily, and if it ever needs a refresh, bring it by and we will clean and polish it in-house.
Do I need an appointment to visit?
Walk-ins are always welcome. For custom consultations or engagement shopping, booking ahead gets you one-on-one time with a jeweler.
Can you help me find my size?
Yes — stop by for a proper fitting, or text our concierge and we will walk you through measuring at home before you order.
