OUR CORE VALUES
Artisan Craftsmanship Meets Ethical Mass Production
Artisan Spirit in Mass Production
We started on the ground floor with manual inlaying and gemstone crafting. Today, we bring that same meticulous, hands-on attention to detail to every bulk order. We believe mass production should never mean a compromise on craftsmanship.
Empathy for the Buyer
Our foundation was built on face-to-face conversations with buyers. We actively listen to the market’s frustrations—from tarnishing to stone loss—and proactively engineer material-specific solutions (like our specialized PVD and E-Coating) to solve them at the source.
Ethical & Sustainable Integrity
Doing the right thing is woven into our daily operations. From maintaining a stable, fairly-treated workforce to securing annual SEDEX audits and strict Prop 65/REACH compliance, we take pride in manufacturing responsibly.
Borderless Partnership
We are a global team with a local touch. Our culture champions clear, rapid communication. With our “Hybrid Advantage” (China manufacturing + US Showroom in San Diego), we tear down geographical barriers to be a true extension of your brand’s supply chain.
THE FOUNDER’S JOURNEY
From Gemstone Artisan to Global Partner
My journey in this industry began when Jasper was 26 years old.
I started on the ground floor as a craftsman, specializing in the delicate art of Semi-Precious Stones (Agate, Mother of Pearl, Tiger’s Eye) and Manual Inlaying.
During this time, I personally learned the art of Manual Inlaying—perfecting how to fit natural stones into metal bases without gaps or glue failure.
I also worked on the front lines of sales. In the early days of my startup, I didn’t just make the products; I sold them. I spoke face-to-face with buyers, listened to their frustrations about fallen stones and fading colors, and understood exactly what the market needed.
Over the years, this passion evolved into a mission to provide
world-class OEM/ODM Jewelry Manufacturing solutions.

FINISHING TECHNOLOGY
Achieve No-Fade Jewelry with Our Finishing
We recognize that tarnishing and oxidation are the primary concerns for jewelry buyers. To solve this, we apply material-specific protective technologies.
For standard stainless steel jewelry, we use PVD vacuum plating at approximately 0.03μm. For custom stainless steel jewelry, we offer a thicker plating range from 0.06μm to 0.1μm to ensure every piece passes a rigorous 72-hour salt spray test. For Brass and Alloys, we add a professional E-Coating (Electrophoretic Coating) layer over our 0.03μm-3 μm real gold plating. This “invisible shield” effectively seals out air and moisture, preventing base metal oxidation and ensuring long-term color retention.
Our commitment to durability extends to high-performance materials. Titanium items are crafted via high-precision CNC machining to maintain hypoallergenic properties while achieving an ultra-smooth, comfortable finish. Tungsten undergoes diamond-wheel polishing for a scratch-proof, mirror-like luster that never loses its brilliance. Furthermore, as manual inlay experts, we utilize meticulous craftsmanship to secure stones—whether setting Agate into steel or Zircon into brass—eliminating the risk of stone loss at the source.
