Why people come here instead of a jewelry store

You deal with Gadi. Start to finish.

Not a counter clerk, not a call center, not a case number. One person who has spent his career grading stones, and who will personally look at yours.

We buy direct.

No auction fees. No consignment cut. No middleman taking a slice of what your piece is worth on the way through.

A private appointment, not a storefront.

An office in North Dallas. No sales floor, no queue, and nobody watching over your shoulder.

If we’re not the right buyer, we’ll tell you.

Some pieces genuinely do better elsewhere. You’ll get a straight answer either way — it costs us nothing, and it’s how we’d want to be treated.

How it works

Send what you have.

Photos, certificates, whatever’s in the drawer. If you don’t know what it is, that’s fine. That’s rather the point.

Get your valuation.

A valuation range from someone who knows what the market is actually paying this week. It’s an estimate of what we’d pay, subject to seeing the piece in person.

Meet in Dallas.

A private appointment at a time that suits you. We look at it together and you get a firm offer. You decide whether to sell.

Three generations of this

The trade Gadi grew up in.

Gadi’s grandfather, Bernard Spiro, was among the first members of the Israel Diamond Exchange when it formed in 1968 — trading rough stones out of Ramat Gan.

Not retail. Not a franchise. Not a “we buy gold” sign in a strip mall. Three generations of looking at stones and knowing, quickly and accurately, what they’re worth.

It’s why the valuation you get here is a real opinion rather than an opening bid.

What people say afterward

Had a wonderful visit with Gadi, very kind, very helpful and knowledgeable… a good deal for both parties is a great deal.
Carly V. · Google review
Professional, transparent, and extremely knowledgeable… I appreciated the honesty and attention to detail, and I felt I received a very fair market value for my jewelry.
Rafi Z. · Google review
I had a diamond ring to sell and they gave me the best offer by far from other dealers, and were very honest and straightforward.

Common questions

Is the valuation really free?
Yes. The estimate is free, with no obligation to sell. A formal appraisal is a separate paid service.
What if I just want to know what it’s worth?
That’s welcome. Our free valuation is an estimate of what we would pay for the piece, with no obligation to sell. If you need a formal appraisal document, ask Gadi about the separate appraisal service.
How do you decide what to offer?
Current market for the metal or the stone, the quality of the piece, and what it will realistically sell for through our wholesale channels. We’ll show you the reasoning — you should understand the number, not just receive it.
Do you offer formal appraisals?
Formal jewelry appraisals typically cost around $150 per item; watch appraisals are around $200 per item. Pricing differs for items valued above $50,000. Contact Gadi to discuss the item and fee.
How do you pay?
Usually by check, with wire transfers for larger amounts. We do not pay in cash. Discuss payment arrangements with Gadi before accepting an offer.
What should I bring to the appointment?
Bring the piece and formal identification. A photo ID is required. Bring any certificates or appraisals you have, but those documents are optional.
Do I need a certificate?
No. Helpful if you have one, entirely fine if you don’t.
Where are you?
North Dallas, by private appointment — 12801 North Central Expressway, Suite 501. We’re not a walk-in store, which means when you come in, the time is yours.
