The three gemstone types we buy
Selling a large emerald, Burmese ruby or Ceylon blue sapphire
We buy only large, high-quality green Colombian emeralds, Burmese rubies and Ceylon blue sapphires, loose or in fine jewelry. The same limits apply to loose stones and mounted jewelry. Tell us what you know about the stone and identify any uncertain details when arranging an evaluation.
Large green Colombian emeralds
Bring a loose emerald or complete ring, pendant or other jewelry. Share any known weight, condition, repairs or treatment information, and explain the basis for a Colombian-origin description. Our Colombian emerald ring guide explains how to prepare the stone and its setting.
Large, high-quality Burmese rubies
To discuss selling a Burmese ruby in Los Angeles, describe the stone and whether it is loose or mounted. Bring any record of weight, treatment or Burmese origin; Burma is now called Myanmar. Keep family descriptions separate from laboratory findings. Certificates are welcome but not required, and an origin description alone does not establish quality or guarantee an offer.
Large, high-quality Ceylon blue sapphires
We buy blue sapphires of the specified quality and Ceylon origin, the trade name associated with Sri Lanka. Bring the stone or complete jewelry with existing reports and any known repair or treatment details. Read our Ceylon sapphire jewelry guide when preparing a piece that also contains natural diamonds.
Reports optional
Bring existing certificates and records if available. You can request an evaluation without them.
Bring the complete piece and what you know
Share the known weight or dimensions, condition, setting and any treatment or origin information. Keep estimates and family descriptions distinct from laboratory findings.
Do not remove a mounted stone or arrange aggressive cleaning to prepare the visit. Bring any report, receipt or repair record you already have.
Describe your gemstone
Tell us about its size, appearance and the jewelry it belongs to, if any.
Discuss the evaluation
We consider the actual stone, its quality, condition and supporting information. An origin claim alone does not guarantee an offer.
Review the purchase terms
Confirm which items the offer includes and your preferred payment arrangement before deciding.
Natural diamonds have a separate scope
Any diamond size. Any diamond shape.
We buy natural, cut and polished diamonds of any size or shape, loose or in jewelry. We do not buy laboratory-grown, uncut or rough diamonds.
Prepare with the right guide
Gemstone selling questions
Which gemstones do you buy?
We buy only large, high-quality green Colombian emeralds, Burmese rubies and Ceylon blue sapphires. Certificates are welcome but not required.
Do I need a gemstone certificate?
No. A certificate or laboratory report is welcome but is not required to request an evaluation. Bring the stone or complete jewelry and whatever information you already have.
Can color prove a gemstone’s origin?
No. Share the source of an origin description, such as a laboratory report, receipt or family history. The actual stone needs examination; appearance alone does not establish geographic origin.
Does the gemstone size requirement apply to diamonds?
We buy natural, cut and polished diamonds of any size or shape, loose or in jewelry. We do not buy laboratory-grown, uncut or rough diamonds.
How can I receive payment?
Cash, bank wire and business check are available for agreed purchases. Confirm the final amount and payment arrangements before accepting.
