The Best Way to Sell Emeralds

Find out what you've actually got before you take a single offer. With emeralds that means two things above all: where the stone came from and how heavily it's been treated. Both move the price enormously, neither is visible to an untrained eye, and a buyer who knows and assumes you don't is in a very comfortable position.

Gold and diamonds are easy to sell. There are a thousand articles telling you how. Have emeralds, or sapphires, or pearls, and it's almost as though gems other than diamonds don't exist, right up until somebody wants to sell you one. Then they're perfect and beautiful and unique.

Why is an appraisal the first step and not the last?

Because with emeralds, the difference between an informed and an uninformed seller is measured in multiples, not percentages.

Two emeralds of identical size and similar colour can be worth wildly different amounts depending on origin, clarity, cut quality and treatment history. Unlike diamonds, where the Four Cs are standardised and widely understood by the public, emerald valuation rests on judgements most sellers have no way to make. Start with a verbal appraisal from a qualified gemologist. You can get one free from me or from one of my GIA Accredited Jewelry Professionals, and if the stone turns out to be significant, that's the point at which a full written appraisal earns its cost.

Walking into a negotiation knowing your stone is a lightly-oiled Colombian rather than a heavily-treated commercial stone changes who is in charge of that conversation.

How much does treatment affect the price?

More than most sellers realise, and this is the part worth reading twice.

Emeralds are included by nature. Almost all of them are clarity-enhanced, usually with oils or resins filling surface-reaching fractures to improve apparent clarity. This is a normal, accepted, long-standing practice, and it is not fraud. What matters is the degree. Grading laboratories describe enhancement on a scale from none through minor, moderate and significant, and the value gap between an untreated stone and a heavily treated one of the same appearance is very large. A genuinely untreated emerald of good colour is rare and priced accordingly.

Treatment also affects care. Oiled stones can be damaged by heat, ultrasonic cleaners and solvents, which is why an emerald should never go into the same cleaner as your diamond rings.

Be completely transparent about any treatment you know of, and expect the same from your buyer. If a buyer won't discuss treatment, that tells you something.

Where does origin come into it?

Colombian emeralds generally command the highest prices, and the market is quite particular about it.

Zambian and Brazilian stones can be beautiful and can be excellent value, but Colombian material carries a premium that has held for a long time. Origin can often be determined by a laboratory from inclusions and trace elements, so it's documentable rather than a matter of opinion. If a stone is significant enough, an origin report can pay for itself several times over.

Who should you actually sell to?

Sell to someone who knows emeralds specifically, not simply someone who buys jewelry.

Research local jewelers and their reputation as buyers, and I hope you'll consider us if you're selling emeralds in San Diego. Online platforms reach more buyers but mean shipping a valuable stone and waiting. Selling in person gets you an immediate evaluation and immediate payment, and lets you watch the stone the whole time.

And a buyer worth dealing with will tell you something against their own interest: if you can afford to wait, the most money is with the person who will actually wear it. A dealer has to leave room to resell. That's not a trick, it's the business, and anyone who pretends otherwise isn't being straight with you.
