Laboratory-Grown Diamonds · Custom Jewelry

The diamond at trade cost. The certificate on the table. One flat fee.

National retailers list the same IGI-certified laboratory-grown diamonds from the same suppliers and mark them up by thousands. We source the exact stone you choose at the trade price, show you the certificate and the invoice, and charge a single flat sourcing fee. Our craft, and our margin, is the setting we build for it.

What We Do

Every piece begins with a certified laboratory-grown diamond and ends at a working jeweler's bench. No showroom markup, no mystery pricing.

Certified Diamond Sourcing

Choose from hundreds of thousands of certified diamonds in the trade network, laboratory-grown or natural. We buy your stone at the trade price, inspect it in hand, verify the certificate directly with the grading laboratory, and deliver it fully insured.

How It Works

The process is the product. You see everything we see.

Pick your stone

Tell us the shape, size, and budget, or bring us a listing you found anywhere online. We search the trade network for it and for better candidates.

See the real numbers

We show you the IGI certificate and the actual trade invoice side by side. You pay the trade cost plus our flat fee. Nothing hidden.

We inspect it in hand

Every stone is received, verified against its certificate, and inspected at the bench before you ever see it.

Set, finished, delivered

Take the loose stone, or have us build the setting. Finished pieces are delivered fully insured with the certificate and our invoice.

About BenchStreet

BenchStreet Jewelers pairs direct access to the wholesale diamond trade with working bench jewelers. The founder came to the trade the honest way: shopping for a friend's engagement diamond, discovering the same certified stone listed at wildly different prices across the big retail sites, and deciding the fix was a jeweler who just shows the invoice. We source through vetted trade networks, verify every certificate directly with the grading laboratory, and put our margin where our work is: the design and the bench, not the stone.

Certificate-First

Every stone is bought against its independent grading report, and every report number is verified on the laboratory's own database before and after we take delivery.

Inspected in Hand

We never ship a customer a stone we have not physically received and examined. Virtual inventory, real inspection.

Insured Door to Door

Stones and finished pieces travel fully insured with signature delivery, from the trade network to our bench to your hands.

Common Questions

Are laboratory-grown diamonds real diamonds?

They are diamonds: pure crystallized carbon, identical in optical, physical, and chemical properties to mined diamonds. They are grown in a facility rather than mined, and we disclose that clearly on every stone, as federal guidelines require.

How long does an order take?

Loose stones typically arrive to us from the trade network, are inspected, and reach you in a matter of weeks; custom settings add bench time, quoted per design. We confirm the timeline in writing with your quote.

Why is your price so much lower?

It is not a discount, it is a different structure. Retailers price the stone with a hidden markup. We pass the trade price through, charge one flat fee you can see, and earn our living on craftsmanship.

What about returns?

Return terms are stated in writing on every quote before you pay. Custom and modified pieces are final sale, which is standard for bench work.

Can you match a stone I found online?

Usually, yes. Send us the listing or the IGI report number. If it is in the trade network, we will quote you the same certified stone at trade cost plus our fee.

Do you buy or trade diamonds?

Not at this time. We source new certified stones and build, repair, and restore jewelry.

Why Transparent Pricing

A laboratory-grown diamond with an IGI report number is the same stone no matter whose website it sits on.

The big online retailers sell from shared supplier lists. The identical certified stone routinely appears on several sites at once, at prices thousands of dollars apart. We would rather show you the invoice and charge a fair, flat fee than pretend the markup is magic. BenchStreet Jewelers
