Sell Your Diamonds to a Buyer, Not a Pawn Shop

Sell diamonds in Phoenix to a buyer who grades the stone in front of you and explains the number before you decide. Gold King Bullion LLC buys diamonds and diamond jewelry at ten partner locations across the Phoenix metro, from Avondale to Casa Grande, and appraises the same stones for insurance and estates. Whether you have one engagement ring, a parcel of melee or an inherited suite you will never wear, there is no obligation to accept an offer. To talk through a stone before you drive over, call (602) 648-7777.

This page covers what we buy, how a diamond is priced, what an appraisal involves and what happens at the counter. If you are still deciding whether to sell, read the pricing section first: most of the gap between two offers on the same stone comes from grading, not from haggling.

What We Buy When You Sell Diamonds

We buy finished diamond jewelry — rings, studs, pendants, bracelets, tennis lines — along with loose stones, old cuts and settings that have lost their partner. We also buy the precious metal in the piece, so a ring with a chipped stone is not a total loss. Estate pieces, single earrings and broken chains with the stone still set are all worth bringing in. We will sort what is worth selling as a stone from what is worth selling as metal, and original boxes and receipts are welcome but never required.

We are buyers and appraisers, not resellers and not collateral lenders. That distinction matters when you sell diamonds: we price the stone for our own inventory or for the refinery, we do not quote a loan against it, and the offer you accept carries no buy-back obligation.

How We Price a Diamond

Diamond value is set by the four Cs — cut, colour, clarity and carat weight — and by whether the stone carries a grading report from a recognised laboratory. A report removes most of the argument: the grade is written down and both sides can read it. When you sell diamonds without one, our gemologist grades the stone in front of you and explains what the grade means in plain terms. The Gemological Institute of America publishes a plain-language guide to how cut is graded, which is worth ten minutes before you sell anything.

Two stones of the same weight can differ several times over in price, which is why we do not quote from a weight chart. We look at the stone under magnification, check for treatments and fractures, and value the stone and the metal separately. If the setting is worth more as metal than the stone is as a stone, we will tell you that too — it happens more often than sellers expect on small stones in heavy settings.

Appraisals for Insurance and Estates

Homeowner policies usually cover jewelry only to an aggregate limit of $10,000 to $25,000, and a single piece worth more than about $1,000 generally has to be scheduled separately. That is why an insurer will ask for a written valuation before it adds a ring to your policy. We prepare that documentation: the stone, the grade, the metal and the replacement value the insurer needs. People who sell diamonds often need the appraisal anyway, for a policy, a divorce or an estate, so ask whether one makes sense before you sell. Turnaround depends on how many pieces you bring. The jewelry appraisal page lists the fees and the scope of each report.

For an estate, we can value the whole collection and buy only the pieces the estate has decided to release. Executors should bring their authority to act. We put the valuation in writing, item by item, so it can sit alongside the estate's other records.

How to Sell Diamonds, Step by Step

1. Bring the piece, any grading report, and photo identification.
2. We examine the stone under magnification and grade it, or read the grade from the report.
3. We value the stone and the metal separately and explain the offer line by line.
4. You decide. Accept the offer, take the piece home, or leave it for an appraisal instead.

Nothing changes hands until you say so. If you want a second opinion before you commit, ask for the number in writing and check it against the report or the grade you were shown. An offer is not a valuation and a valuation is not an offer; we will tell you which one you are looking at.

What to Bring

Bring photo identification, and any grading report, appraisal or receipt you already have. A report helps but is not required, and an old appraisal is useful mainly as a record of what the piece was described as when it was bought. If the piece belongs to an estate, bring the executor's authority or ask the executor to come with you. Our reporting requirements page explains when a sale triggers a 1099-B and what we are required to report.

Where to Sell Diamonds in the Phoenix Metro

We buy diamonds at ten partner locations across the Phoenix metro, from Avondale to Casa Grande, and the counters are open seven days a week. The locations page lists every store with its address and hours, and the contact page carries the map and our corporate line. If you are driving in from Scottsdale, Mesa, Tempe, Chandler or Glendale, call ahead and ask whether the gemologist is on site that day: an appraisal takes longer than a straight purchase, and we would rather you did not make the trip twice.

Questions About Selling Diamonds

Do you buy a diamond without a certificate? Yes. A certificate makes the grade easier to agree on, but our gemologist can grade an uncertified stone.

Can I sell the stone and keep the setting? Usually. Ask before we begin and we will tell you whether the setting has enough metal value to be worth separating.

Do I need an appointment? Not for a purchase offer. For an appraisal, call ahead so the gemologist is available when you arrive.

Is there a charge to find out what it is worth? Appraisal fees are published on the jewelry appraisal page. A purchase offer is not the same service as a written valuation.

If you are ready to sell diamonds in Phoenix, start with the stone rather than the setting. Bring it in, let it be graded in front of you, and ask what the grade means for the number on the page.
