Lab-grown diamond FAQ
Clear answers before a custom jewelry quote.
These answers help buyers understand NKGEM, lab-grown diamonds, certificates, production timing, dispatch route, and quote boundaries before placing an order.
What is a lab-grown diamond?
A lab-grown diamond has the carbon crystal structure of diamond, but it is grown in a laboratory environment. NKGEM describes it clearly as lab-grown and does not quote it under mined-stone categories.
Is lab-grown diamond the same as moissanite or cubic zirconia?
No. Lab-grown diamond is not moissanite, cubic zirconia, glass, rhinestone, or a diamond simulant. Those are different materials and should be described separately. See the material guide before requesting a quote if you are comparing options.
Are NKGEM lab-grown diamond main stones certified?
Every selected NKGEM lab-grown diamond main stone is confirmed with its third-party IGI report and official laser inscription. The exact documentation belongs to the selected stone and is checked for the individual order. Certificate numbers and report images are not published on public product pages by default. See the NKGEM certificate guide for the quote checklist.
How long does custom production take?
Production and dispatch timing is confirmed for each order after the stone, specifications, construction, QC plan, quote, payment, and destination route are checked. Complex custom pieces can require additional time.
Where can NKGEM dispatch from?
Hong Kong dispatch is available for suitable orders. Production coordination, sourcing details, carrier route, duties, taxes, and order documents are confirmed per order before fulfillment.
Are public price ranges final prices?
No. Public ranges are guides. A final quote depends on current stone availability, certificate needs, metal, ring size, side stones, labor, payment method, shipping, taxes, and destination.
How do I request a quote?
Send product type, stone shape, carat direction, color, clarity, metal, ring size, budget, destination, certificate needs, and timing. Email Joey at joey@nkgem.com or message NKGEM on WhatsApp. You can also use the NKGEM quote guide.
Which lab-grown diamond shape should I choose?
Start with the visual direction: round, oval, emerald, princess, cushion, radiant, pear, or marquise. The shape affects measurements, setting planning, certificate direction, and quote path. If you are unsure, use the NKGEM shapes guide before sending your quote request.
Does NKGEM support wholesale or sample orders?
Yes. NKGEM can discuss sample orders, small-batch wholesale directions, repeat SKU requests, retailer or reseller inquiries, and suitable packaging direction through the wholesale inquiry page. Final terms depend on the current style, stone, metal, quantity, dispatch route, and order details.
What does Hong Kong-standard setting mean?
NKGEM uses Hong Kong-standard setting as a quality benchmark for stone security, prong symmetry, clean finishing, polished comfort, QC, and buyer-ready presentation. It is not a blanket claim that every order is Hong Kong-origin.
Can NKGEM make a ring from a reference image?
A reference image can be used to explain style direction, but NKGEM confirms an original custom variation before production. Designer-copy, brand imitation, or protected design requests are not accepted as exact-copy commitments.
What details are needed before a final quote?
A final quote needs the current center stone option, certificate need, metal, ring size, side-stone or setting details, production complexity, destination, shipping route, duties or taxes boundary, payment method, and timing check.
Can I start with a loose lab-grown diamond before choosing a setting?
Yes. Buyers can start with a loose lab-grown diamond direction first, then confirm whether NKGEM should also make the ring, pendant, earrings, or another setting. The stone choice, certificate preference, and setting plan are checked together before the final jewelry quote.
What if I only know my budget but not the exact 4Cs?
Send your budget, destination, deadline, preferred jewelry type, and any visual direction you like. Joey can use that information to narrow the realistic stone and setting path before asking for more exact parameters.
Can NKGEM source the center stone and make the jewelry together?
Yes. NKGEM can discuss center-stone sourcing and jewelry production in one quote-first flow. Current stone availability, certificate direction, metal, size, setting work, QC, dispatch route, and final price are confirmed before production.
Can NKGEM make earrings, pendants, bracelets, necklaces, or samples?
Yes. NKGEM can discuss custom lab-grown diamond jewelry beyond rings, including earrings, pendants, bracelets, necklaces, samples, and small-batch directions. The first brief should include category, stone target, metal, size or length, quantity, budget, destination, and deadline.
Can NKGEM make an exact copy of a designer ring?
No. Reference images can explain taste, proportion, stone shape, or setting direction, but NKGEM does not accept exact designer-copy or protected-design commitments. Custom requests should move toward an original variation.
How is main-stone documentation confirmed?
Every selected NKGEM lab-grown diamond main stone is confirmed with its third-party IGI report and official laser inscription. Report details are checked against the actual selected stone before the final quote instead of being treated as a generic product-page specification.
Why does NKGEM ask for my destination before quoting?
Destination affects dispatch route, carrier choice, insurance, duties, taxes, delivery risk, and payment handling. It is part of the quote gate, not a shipping formality.
