Wholesale Sourcing Guide
How to Order Custom Gemstone Jewelry Wholesale from Thailand
Thailand exported $9.6 billion worth of gems and jewelry in 2024 — a 10.99% year-over-year increase. For retailers and brands seeking custom gemstone pieces, Thai manufacturers offer a rare combination of skilled craftsmanship, competitive pricing, and production capacity that few countries can match.

What Kinds of Thai Suppliers Offer Custom Gemstone Jewelry?
OEM / ODM Factories
Handle full design-to-shipping in-house. You negotiate based on actual production costs. Quality control happens in real-time under one roof.
Traders & Brokers
Farm orders to multiple workshops. Lower visibility into production. Less suited for precision custom gemstone work.
Bangkok's Gemopolis Industrial Estate houses over 200 jewelry manufacturers within its 25-hectare campus. Established in 1990 as a tax-free industrial zone, it offers import duty exemptions on raw materials and concentrates production and export logistics in one location.
What Is the Usual MOQ for Custom Gemstone Pieces?
Sterling Silver (Custom)
30–50 pieces per design. Lower material cost allows smaller runs. Ready-stock from $1,000.
Solid Gold (Custom)
50–100 pieces per design. Higher material cost and risk require larger commitments.
Made-to-Order
From $2,000 minimum order value. Production timeline 30–45 days after deposit.
Sample Orders
25–100% surcharge above wholesale price. Many factories credit sample costs against bulk orders.
How Do I Vet a Reputable Manufacturer?
Request documentation before discussing designs. A legitimate manufacturer provides their Thai Department of Business Development registration, export license credentials, and factory photos showing actual production equipment. Ask for client references you can contact directly.
"Gemstone certification matters enormously for colored stone pieces. Factories working with rubies, sapphires, and emeralds should provide documentation from recognized laboratories."
Key vetting requirementThe Gemological Institute of America (GIA) offers verification services where you can check any GIA report number against their database. Physical visits remain the gold standard for vetting, though video tours are widely available for overseas buyers.
Which Documents Should I Request Before Placing an Order?
Start with a pro-forma invoice detailing exact specifications: metal type and karat, stone types and carat weights, plating thickness in microns, and all finishing details. CAD (computer-aided design) renderings show exactly what your finished pieces will look like before production begins — reject vague sketches and insist on detailed renders.
The Responsible Jewellery Council (RJC) offers chain-of-custody certification for gold, silver, and platinum that tracks materials from source through finished product. Gemopolis-based factories operate under Industrial Estate Authority of Thailand oversight.
Natural gemstone selection at a Thai factory — stones arrive rough and are cut in-house before setting.
How Do I Brief My Design Requirements?
Stone specifications need exact parameters: sizes in millimeters, shapes (round brilliant, cushion, emerald cut), quality grades, and whether you accept heated or treated stones. Metal specifications include alloy composition, not just karat weight — 18K gold can contain varying proportions of copper, silver, and zinc affecting final color and hardness.
"If you require untreated stones, state this explicitly — heat treatment remains standard practice in Thailand for rubies and sapphires."
Critical specification notePackaging and branding details complete your brief. Many factories offer private-label services including custom boxes, pouches, authenticity cards, and logo stamping. Provide vector files (AI or EPS format) for any branding elements.
What Is the End-to-End Production Timeline?
Simple Designs
Sample development: 5–7 days. Existing stone cuts and standard alloys.
Complex Designs
Prototype: 2–3 weeks. Custom stone cutting or unusual techniques.
Mass Production (100–500 pcs)
30–45 days after sample approval.
Peak Season
September–January. Allow extra time. Larger orders may extend to 60 days.
Gemstone sourcing can add time. While Thai factories maintain stock of common stones, Chanthaburi Province — 230 km southeast of Bangkok — serves as Thailand's colored gemstone trading hub with access to rubies, sapphires, and regional mines.
What Payment Terms and Incoterms Are Standard?
New Customers
50% deposit before production. Balance before shipment. Non-negotiable once goods leave Thailand.
Established Relationships
30% deposit may be available. Track record of consistent ordering helps.
Payment Methods
Wire transfer (T/T) for large orders. PayPal available with 3–4% fee for smaller amounts.
Incoterms
FOB Bangkok (buyer takes from freight forwarder). DDP (seller manages customs). EXW excludes all shipping.
What Import Duties and VAT Will I Pay?
United States (HS 7113)
Silver jewelry: lower rates. Gold pieces: 5–6.5% duty. Thai VAT (7%) refunded on export.
European Union
2.5–4% import duty + VAT at destination rate (19–21% depending on country).

Request Samples & Quotation
Send design files (technical drawings, reference images) with target specifications and estimated quantities. Request itemized quotes showing metal, stones, labor, and finishing as separate line items.
Confirm Pro-Forma Invoice, Pay Deposit & Approve CAD
Factory issues a formal pro-forma invoice. Pay agreed deposit (often 100% for samples). Review CAD models carefully — confirm all dimensions, stone positions, bail sizes, and clasp types before authorizing production.
Production & In-House Quality Control
Ask for photos after casting and after stone setting. Address concerns immediately — corrections mid-production cost less than post-production rework.
Final Payment, Inspection & Shipping
Consider third-party inspection before paying ($200–500 depending on scope — SGS, Bureau Veritas both operate in Thailand). Factory prepares commercial invoice, packing list, and certificate of origin. Most ship via DHL, FedEx, or UPS — 3–7 days to North America and Europe.
What About Lab-Grown Gemstones?
Thai factories increasingly work with laboratory-created stones, offering them at 50–70% below mined equivalents. US FTC guidelines and EU regulations require clear disclosure of laboratory origin. Color consistency improves significantly with lab-grown options — useful for commercial collections requiring uniform colorways across production runs.
How Do Packaging and Branding Add-Ons Work?
Most Thai factories offer complete packaging solutions beyond basic protective pouches — custom boxes, branded tissue paper, authenticity cards, and care instructions. Logo stamping on jewelry pieces requires tooling; expect one-time die charges. Provide your logo in vector format (AI or EPS). Lead times for packaging often exceed jewelry production, so order packaging materials early in your timeline.
What Sustainability Certifications Matter?
Beyond RJC certification, Fairmined certification applies to artisanally-mined gold from responsible sources. Over 2,000 companies across the global jewelry supply chain now hold RJC certification. Thailand's Department of Industrial Works enforces environmental regulations for manufacturing facilities.
Goldlip's factory in Trat Province pays 30% above local average wages and provides full benefits including maternity leave and pensions.
Social compliance in practiceWhich Trade Shows Connect Buyers with Thai Manufacturers?
The Bangkok Gems and Jewelry Fair runs twice yearly — February and September — at Queen Sirikit National Convention Center. The February 2025 edition drew over 1,100 exhibitors across 2,600 booths, generating an estimated 3.5 billion baht in trade value. Colored gemstones account for nearly 50% of exhibitor space.
Trade fair participation allows hands-on quality assessment impossible through online communication alone. Many factories offer special show pricing and lower MOQs for orders placed during fair dates. Regional shows in Hong Kong, Singapore, and Dubai also feature Thai manufacturers.
Frequently Asked Questions
FAQ
Can I order custom jewelry from Thailand without visiting the factory?
Yes. Most Thai manufacturers work with international clients entirely through email, video calls, and courier samples. Request a virtual factory tour to assess facilities and meet your production team. Many successful wholesale relationships begin without in-person meetings.
How do I protect my designs when working with overseas manufacturers?
Professional factories sign non-disclosure agreements covering your designs. Thailand's intellectual property laws provide legal protection. Work with established manufacturers who value long-term relationships over short-term copying opportunities.
What happens if my order arrives with quality defects?
Document defects immediately with photographs and formal written notification to your supplier. Reputable factories offer remake or repair options for legitimate quality issues. Pre-shipment inspection prevents most problems from reaching you. Discuss dispute resolution procedures before ordering, including who bears shipping costs for returns.
Are Thai jewelry factories open to small businesses and startups?
Many Thai manufacturers welcome smaller buyers, particularly those with clear growth potential. Some factories maintain lower MOQ programs specifically for emerging brands. Be upfront about your current volume and growth plans — factories invest in relationships with buyers who demonstrate professional communication and consistent ordering patterns.
How do currency fluctuations affect pricing from Thai suppliers?
Thai factories typically quote in US dollars, protecting you from baht fluctuations. Metal costs (gold, silver, platinum) vary daily based on global commodity markets. Lock in metal pricing when you confirm orders to avoid surprises on extended production timelines.
Can I request custom designs or modifications?
Yes, particularly for ongoing wholesale partners. Common modifications include different gemstones, metal finishes (rhodium, gold, oxidised), and ring sizing adjustments. Full custom designs are possible but require lead time and minimum quantity discussions. Contact us to start that conversation.
