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.
Colored Gemstone Jewelry
Sapphires, rubies, emeralds, and other precious and semi-precious stones set in gold or platinum. Natural, untreated stones and certified gems evaluated at full market value.
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 you pay more than just the gold melt value on diamond jewelry?
Yes — and this matters a lot. Many buyers strip diamond jewelry down to melt and ignore the stones entirely, especially on smaller diamonds. We evaluate diamonds separately from the metal and pay for both. On significant stones or designer pieces, the difference can be substantial.
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.

We Buy Diamond and Estate Jewelry in San Antonio
Free offers for diamond jewelry, estate jewelry, designer pieces, and fine jewelry in San Antonio.
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.
Sell Emeralds, Rubies & Sapphires in San Antonio
We buy colored gemstone jewelry — emeralds, rubies, sapphires, and other fine gemstones — whether the stones are set in a ring, pendant, or bracelet, or loose and unmounted. If you have paperwork such as a GIA or AGL report, grading certificate, or original purchase receipt, bring it along; it helps us evaluate the stone quickly and accurately, though it isn't required to get an offer. Value depends on the stone itself, the setting, and the overall piece, and every combination is different, so each item is evaluated individually rather than against a generic price list.
Several factors drive the value of a colored gemstone: color, clarity, and cut quality; origin and any treatment history when that's documented; the metal and craftsmanship of the setting; whether the piece carries a recognized brand name; overall condition; and current resale demand for that particular stone and style. A GIA or AGL report can support a stronger offer on a well-documented stone, but plenty of colored gemstone jewelry comes to us without paperwork, and we're equipped to evaluate it on sight. Every evaluation happens in person, in our showroom, in front of you — we don't ask you to ship gemstone jewelry off-site for review.
Selling an Engagement Ring in San Antonio
Selling an engagement ring is often tied to a difficult or personal situation, and we handle every one discreetly and without judgment — no questions about why you're selling, just a straightforward evaluation. We look at the center stone using the standard 4 Cs (cut, color, clarity, and carat weight), the setting and any side stones, the metal type and purity, and whether the ring carries a recognized brand name such as Tiffany or Cartier, which can add to its value beyond the stone and metal alone.
The evaluation is free and takes place in our showroom while you wait, with no appointment necessary and no obligation to sell. If you accept our offer, payment is made the same day, in person. If the number isn't right for you, there's no pressure to accept — you keep the ring and leave with a clearer sense of its value either way, and you're welcome to get a second opinion before making a final decision.
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.
Do you buy emeralds and colored gemstones?+
Yes, we buy emeralds, rubies, sapphires, and other colored gemstones, whether they're set in jewelry or loose. Value depends on the stone's quality, any documented origin or treatment, the setting, and current resale demand, and every piece is evaluated individually and in person in our San Antonio showroom. A GIA or AGL report can help support a stronger offer, but it isn't required — bring the piece in with any paperwork you have, and we'll give you a straightforward evaluation on the spot.
How do I sell my engagement ring in San Antonio?+
Bring the ring into our San Antonio showroom for a free, no-appointment evaluation. We'll examine the center stone using the 4 Cs, the setting, the metal, and any brand markings, then give you a straightforward offer on the spot — handled discreetly, with no questions asked about the circumstances. If you accept, you're paid the same day. If not, there's no obligation and no pressure; you're free to keep the ring or get a second opinion elsewhere.
