Call Now — (210) 735-7131Submit Your Jewelry for an OfferHow It Works — 3 Simple Steps
1. Bring It In
Walk in with your jewelry — any condition, any era, with or without paperwork. No appointment needed. Open Monday–Friday 9AM–5PM and Saturday 9AM–4PM at 2622 NW Loop 410.
2. Expert Evaluation
We evaluate diamonds for cut, color, clarity, and carat weight. Precious metal content is tested with industry standard equipment. Designer pieces and estate jewelry are assessed against current market demand. We walk you through every number before making an offer.
3. Get Paid Same Day
Accept our offer and walk out with cash the same visit. Single pieces or full estate collections — we handle them all and pay immediately. No waiting, no consignment, no delays.
What We Buy
Diamond Jewelry
Engagement rings, diamond studs, tennis bracelets, pendants, and all diamond pieces. Loose stones and set diamonds both accepted. GIA, AGS, and other certified stones evaluated against current market pricing.
Estate & Antique Jewelry
Victorian, Edwardian, Art Deco, Art Nouveau, Retro, and Mid-Century pieces. Inherited collections, grandmother's jewelry, and estate liquidations handled with care and expertise.
Designer & Signed Pieces
Tiffany & Co., Cartier, Van Cleef & Arpels, David Yurman, Bulgari, and other signed jewelry. Designer provenance can significantly increase value beyond the metal and stone content alone.
Platinum Jewelry
Platinum rings, settings, bracelets, and chains. Platinum is significantly denser and more valuable than white gold — we test and pay accordingly, not generic white metal prices.
Broken or Incomplete Pieces
Missing stones, broken clasps, bent settings, incomplete sets — condition does not disqualify a piece. If it contains precious metal or genuine gemstones, it has value and we want to see it.

Frequently Asked Questions
How do you determine what my jewelry is worth?
We evaluate jewelry based on precious metal content, diamond quality (cut, color, clarity, and carat weight), gemstone identification and grade, designer or maker signatures, and current market demand. We walk you through each component of the offer so you understand exactly what you're being paid for.
Do you buy jewelry with missing or damaged stones?
Yes. Missing stones, broken prongs, bent settings, and general wear do not disqualify a piece. The precious metal content and any remaining stones still have value. Bring it in regardless of condition and we'll tell you exactly what it's worth.
Do I need a GIA certificate or appraisal to sell?
No. A GIA certificate or independent appraisal can support the value of a stone, but we evaluate diamonds ourselves and don't require paperwork to make an offer. If you have a certificate, bring it — it helps. If you don't, we'll assess the stone directly.
Do you buy designer jewelry like Tiffany or Cartier?
Yes. Designer and signed jewelry from Tiffany & Co., Cartier, Van Cleef & Arpels, David Yurman, Bulgari, and other recognized houses carries value beyond the metal and stone content. We recognize designer provenance and factor it into our offer.
Do I need an appointment?
No appointment needed. Walk in Monday–Friday 9AM–5PM or Saturday 9AM–4PM at 2622 NW Loop 410. For large estate collections, calling ahead at (210) 735-7131 is appreciated so we can give your pieces the dedicated time they deserve.

Selling Diamond Jewelry in San Antonio?
Lone Star Coins buys diamond jewelry, engagement rings, estate jewelry, and fine jewelry in San Antonio with free in-store evaluations. Bring one ring or a full estate group and we will explain the factors that affect the offer.
Jewelry sellers visit us from across South Texas when they want a face-to-face evaluation instead of a mail-in quote. Selling locally lets you avoid shipping jewelry away, waiting for a remote buyer, or accepting a generic metal-only quote for a piece that may have diamond, brand, or design value.
Sell Diamond Jewelry in San Antonio
We buy diamond rings, engagement rings, earrings, bracelets, pendants, and other fine jewelry. A GIA report or prior appraisal can help, but it is not required for us to evaluate the piece.
Diamond jewelry is reviewed for stone quality, setting, metal content, condition, brand, and current resale demand. We explain what matters before you decide whether to sell.
Estate Jewelry Buyer in San Antonio
Estate jewelry often includes a mix of gold value, gemstone value, design value, and sentimental history. We take the time to separate those pieces instead of treating every item as scrap.
If you are settling an estate, bring the full group. We can evaluate fine jewelry alongside coins, bullion, watches, and precious metals so the collection is handled consistently.
Why Jewelry Sellers Choose Lone Star Coins
Fine jewelry sellers need an offer that considers more than gold weight. We look at diamonds, gemstones, precious metal content, condition, designer value, resale demand, and estate context.
Because the transaction happens locally in San Antonio, you can ask questions, keep control of your jewelry, and receive same-day payment if you decide to sell.
Common Questions
Do I need paperwork to sell diamond jewelry?+
No. Bring any GIA reports, appraisals, receipts, or boxes if you have them, but we can evaluate jewelry without paperwork.
Do you buy estate jewelry collections?+
Yes. We buy individual pieces and full estate jewelry groups, including mixed lots with coins, bullion, and watches.
Is fine jewelry priced only by gold weight?+
Not always. Stones, design, brand, condition, and resale demand can add value beyond the metal content.
