Everything you need to know about our manufacturing process
Four core advantages built into our dual-factory closed-loop model
China precision crafting + Thailand origin certification. One seamless supply chain — from design sketch to global delivery.
JingZhi factory in Guangzhou specializes in complex stone setting, intricate structures, and high-difficulty designs with sub-millimeter accuracy.
FREEZONE factory + Thailand origin certification = 18–36% lower landed cost vs. mainland China factories. Thailand pays 19% reciprocal tariff; China-origin jewelry faces a 42–66% total duty stack (base + reciprocal + IEEPA + Section 301). Sterling silver and fine jewelry are typically Section 232 exempt.
Sanhetai in-house plating — thick gold coating, color consistency, wear resistance. No outsourced quality risks. Full traceability.

Expert knowledge from LY Jewelry — 25 years of manufacturing experience distilled into practical guides for jewelry brands and buyers.
Rated 4.9/5 from 127+ verified B2B buyers across 24 countries
"We've been sourcing from LAIYI for 3 years now. Their 18-36% tariff savings on US imports is a game-changer compared to our previous China suppliers. Sterling silver quality is consistently high — every shipment passes our QC. The 10-day reorder turnaround is reliable, and their team communicates in fluent English which makes coordination effortless."
"As a European jewelry brand, we have very high standards for finishing. LAIYI's stone-setting work is on par with Italian manufacturers at a fraction of the cost. Their electroplating facility in Samut Prakan produces beautiful, even finishes — we've tested rose gold, K-gold, and rhodium, all with consistent quality. SGS certification gave us confidence from day one."
"Our boutique chain in Tokyo requires precise, delicate designs. LAIYI handles our custom CAD work beautifully and the MOQ of 10 pieces lets us test new designs without huge commitments. The AGJA factory visit certification showed us their attention to detail. Highly recommend for brands needing flexibility with premium quality."
"What sets LAIYI apart is their communication. Terence responds within hours, samples arrive in 7-10 days, and production updates are consistent. We've placed 8 orders totaling 12,000+ pieces and every one has been on time. The Certificate of Origin gives us confidence in the 19% reciprocal tariff rate for our US-bound pieces."
"Even as a Chinese company, we source specific designs from LAIYI's Bangkok facility because their plating quality surpasses most mainland factories. The dual-factory model (JingZhi in Guangzhou + LAIYI in Bangkok) gives us access to both precision casting and Thai finishing. Communication in Chinese is smooth. Minor delays during Thai holiday season, but they always communicate in advance."
"French customers demand elegance and quality. LAIYI's silver pieces have that European aesthetic with Thai craftsmanship. We especially love their K-gold plating — looks identical to solid gold at a fraction of the price. The 12-step manufacturing process (visible in their factory tour) is impressive. REACH compliance documentation is thorough."
"We switched from a Korean supplier to LAIYI in 2024 and our defect rate dropped from 4% to under 0.5%. Their in-house QC is rigorous — every piece is checked before plating AND after. The Sanhetai plating facility can handle 20,000+ pieces/day, perfect for our seasonal restocks. The free zone export through LY Trade simplifies our Canadian import duties."
