"We’ve been burned by inaccurate grading before. With this team, every IGI report matched the stone perfectly under our loupe. The Bulk Parcel pricing also improved our margins by 18% this quarter."
Elena Rossi
Rossi Fine Jewelry, Milan 🇮🇹
"As a gemologist, I’m extremely picky about clarity grading. Their VS2 stones are truly eye‑clean, no hidden milkiness. Finally a supplier whose grading aligns with lab standards."
Dr. Amir Hassan
Hassan Gem Lab, Beirut 🇱🇧
"The mold fee waiver on orders over 100 pieces was a game‑changer for our new bridal line. Production hit the 15‑day deadline exactly as promised, and the finishing quality exceeded our sample."
David Chen
Lumina Bridal, Toronto 🇨🇦
"We’ve sourced from them for 3 years across 12 bulk orders. Zero customs delays, consistent color matching across parcels, and their account manager actually understands jewelry specs. Rare in this industry."
Raj Patel
Patel Gems Wholesale, Dubai 🇦🇪
"As a small boutique, I was nervous about MOQs. Their Small Batch tier let me test 30 pieces risk-free. Video selection was transparent, and they proactively updated me at every production stage."
Amara Johnson
Gilded Thread Boutique, Atlanta 🇺🇸
"We switched from another vendor after receiving misgraded stones. Here, the video selection showed exact inclusions, and the physical goods matched perfectly. Trust is earned, and they’ve earned ours."
Maria Gonzalez
Galería de Joyas, Mexico City 🇲🇽
"They reproduced our vintage design CAD perfectly, including the hidden halo detail. Production took 18 days as quoted, not 30. Communication via WhatsApp was instant and professional."
Carlos Mendez
Joyería Antigua, Bogotá 🇨🇴
"We compared quotes from 5 factories. Their mid‑tier pricing offered the best balance of quality and cost. The free re‑polishing service on bulk orders sealed the deal."
Fatima Al‑Mansoori
Desert Rose Jewelry, Abu Dhabi 🇦🇪
"After 4 years and 30+ orders, consistency hasn’t wavered. Stone matching across parcels is always accurate, and they proactively suggest alternatives when supply is tight."
Michael Chang
Chang Heritage Gems, Singapore 🇸🇬
"As a startup, the Small Batch MOQ let us test market demand without overcommitting. When we scaled to 100 pieces, the unit price dropped exactly as their table showed. No bait‑and‑switch."

Questions Buyers Ask Before Placing an Order
Have you a question?
What is your MOQ for custom orders?
For finished OEM jewelry: 10‑29 pcs per design for small‑batch bulk orders, and 100+ pcs per design for large‑volume bulk production. Sample‑only orders are available from 1‑9 pcs with full mold‑setup fees applied.
For loose gemstones: 10‑49 carats for standard wholesale, 50+ carats for the lowest bulk rate. 1‑9 carats is for sampling purpose only.
How long does sampling take?
CAD rendering within 48 hours after receiving your sketch or reference image. Once you approve the 3D model, the physical sample is ready in 7–10 business days (including casting, stone setting, and polishing). Shipping adds 3–5 days via DHL/FedEx.
Can you work from my CAD file or sketch?
Yes. We accept finished CAD files, hand‑drawn sketches, mood‑board photos and reference pictures. Our internal CAD team can redraw and optimize sketches for manufacturability. Minimum detail requirement: a clear reference showing overall style, approximate stone sizes, and metal color preference.
What certifications do your gems come with?
All center stones above 0.3ct come with GIA, IGI, or GRS certificates (your choice). For smaller accent stones, we provide in‑house grading reports covering cut, color, clarity, and carat weight. Third‑party certification is available for any stone upon request, with a small processing fee.
What is your quality inspection process?
Every piece goes through 4 inspection stages: (1) post‑casting surface check, (2) pre‑setting stone matching, (3) post‑setting security check under 10x loupe, and (4) final QC before packing including weight verification and polish inspection. We also provide pre‑shipment photos or video for your approval before dispatch.
What warranty do you provide?
We guarantee all workmanship for 12 months from delivery. If any piece has a manufacturing defect (stone loosening, clasp failure, plating peeling), we will repair or replace it free of charge. Simply send photos within 30 days of receipt and we'll resolve it within 5 business days. Return shipping for defective items is on us.
