E · VVS2 · Lab Grown
One supplier for
everything you used to
call five people for.
Most jewelers we work with have learned to live with a fragmented lab-grown supply chain — one vendor for cert loose, one for melee, one for jewelry, one for antique cuts they have to special-order.
We built Guru Diam for the jewelers who are tired of that. Antique cuts, fancy colors, fancy color melee, finished jewelry, and custom engagement rings — all in one inventory, all in one shipment, all with one relationship.
Today 2,000+ jewelers, retailers, and designers source from our B2B wholesale program. We're the only major lab-grown house that specializes in calibrated fancy color melee and matched pairs — categories most suppliers refuse to touch at scale. And we back it up with custom engagement rings finished in 4 to 6 days, not 4 to 6 weeks.
JCK 2026 is our fifth consecutive year at the show. Every year we bring more specialty inventory — because the show is where our best customer relationships start.
What you'll see at Booth #5109
Specialty lab-grown categories, ready for in-person inspection.
Calibrated Fancy Color Melee
Yellows, pinks, blues — calibrated for setting work. 1.5 mm to 4 mm rounds, available in matched pairs and parcels. The kind of melee most jewelers source from three different vendors. We carry it as inventory. Bring your size requirements — we'll pull a parcel for you.
Antique Cuts
Old miner, old european, rose, hexagonal, kite, MOVAL, trilliant. Lab grown, IGI and GIA certified, hand-cut character preserved. Most lab-grown houses don't even attempt antique cuts. We specialize in them. 30+ stones in stock at the booth across all major shapes.
Fancy Color Diamonds
Fancy yellow, fancy pink, fancy blue. IGI and GIA certified. Loose stones from 0.50 ct to 5 ct+, with the colors and saturations your customers ask for and your usual supplier doesn't stock. 50+ fancy color loose stones at the booth, all certified.
Custom Engagement Rings — in 4–6 Days
White-label by default. Send the spec, get a finished ring back in your hands inside a week. Stone, setting, polishing — all in-house. Most custom ring suppliers take 2 to 6 weeks. We deliver in 4 to 6 days. Live custom ring demo at the booth — see the pipeline in action.A first look at what's in our JCK booth

Try one stone. No commitment.
Most jewelers we talk to want to try us. The hesitation isn't price or quality — it's the risk of a first order with a new supplier going wrong.
Here's how we make that risk close to zero:
Memo terms. Pick a stone — antique cut, fancy color, melee parcel, anything from our inventory. We ship it. You pay only when you sell it. If it doesn't sell, you ship it back. No paperwork, no penalty.
One stone. No risk. See for yourself.
Not ours — theirs.
I used to call five suppliers and pay five shipping bills. Now I call Guru Diam once and it all comes in one box.
Their service is on a different level. The custom ring we needed in a week was on my client's finger in five days.
Nobody turns it around faster. When my customer says yes, I have a stone in hand by the end of the week.
