Sell a Large, High-Quality Gemstone Ring in Los Angeles
Cash 4 Gold & Diamonds buys large, high-quality gemstones, including green Colombian emeralds, Burmese rubies and Ceylon blue sapphires. Certificates are welcome but not required. Bring the complete ring and existing records for evaluation.

Our focus: large, high-quality gemstones
Our gemstone buying is limited to large, high-quality stones. Green Colombian emeralds, Burmese rubies from Myanmar and Ceylon blue sapphires from Sri Lanka are examples of our focus. Certificates are welcome but not required. Describe what you have so we can discuss an appropriate evaluation.
This is separate from our diamond buying: we buy natural, cut and polished diamonds of any size or shape. We do not buy laboratory-grown, uncut or rough diamonds.
Start with what you know about the ring
Write down the name used on the original receipt, any markings inside the band, and repairs you know about. Describe an unknown stone as unknown. A blue stone is not enough evidence to call a ring a sapphire, and a family description does not establish a geographic origin.
Bring the ring intact. The setting may limit what can be measured or examined, but removing the stone at home can damage both parts. Ask what can be assessed while it is mounted and whether further examination would meaningfully change the purchase decision.
Discuss the gemstone and the setting separately
Stone size alone does not explain quality. For example, GIA's sapphire guide discusses color, clarity, cut and carat weight. Different gemstone varieties need their own assessment; a diamond grading scale cannot simply be applied to every colored stone.

Ask which identification or treatment information is known, which comes from a report, and which remains uncertain. Then ask how the metal, accent diamonds, maker's marks and condition of the ring affect the total offer. Our sapphire and diamond jewelry guide covers pieces with more than one type of stone.
Organize the paperwork without buying unnecessary reports
Keep the laboratory report with the matching ring. A purchase receipt, insurance schedule and repair invoice can each add context, but they serve different purposes. If you cannot match a document confidently, bring it and explain the uncertainty.
- Bring existing reports and the original sales description, if available.
- Note a chipped stone, loose setting, resizing or replacement stone.
- Keep any original box and detached parts with the ring.
- Photograph the item for your own inventory before the visit.
Ask whether an additional laboratory report is useful before paying for one. Its cost and turnaround should make sense for the actual piece and your reason for selling.
A purchase offer answers a different question from an appraisal
A purchase offer states what a buyer is prepared to pay under the stated terms. A formal appraisal identifies its purpose and valuation basis. GIA's appraisal guidance explains that GIA grades and identifies gems but does not assign their monetary value.
For an insurance or estate assignment, discuss the required document with the professional requesting it. For a sale, compare purchase amounts for the same ring, with the same stones and accessories included. An insurance replacement figure is not a promised resale amount.
Arrange a gemstone-ring evaluation in Downtown Los Angeles

Can I bring a ring without a gemstone report?
Yes. Bring what you have and identify any missing information. The actual ring needs examination; a photograph or a seller's description cannot settle every identification question.
Should I clean or repair the ring first?
Discuss its condition before spending money on repairs or using a cleaning treatment. Keep the stone and setting together, and point out any loose or damaged parts when presenting the ring.
