About Custom Jewelry Manufacturers - Tianyu Gems
Built on Craftsmanship. Grown through Innovation.
Wuzhou Tianyu Gems Co., Ltd. was officially established in 2014, with roots tracing back to 2001. Before the company was founded, its predecessor focused on the production of synthetic gemstones and jewelry, laying the foundation for the craftsmanship, technical knowledge, and manufacturing discipline that continue to define Tianyu today.
Based in Wuzhou, Guangxi — one of China’s most important gemstone processing centers — Tianyu Gems has grown from a gemstone-focused manufacturer into a trusted partner for moissanite, lab-grown diamonds, lab-created gemstones, and custom jewelry.
Over the years, we have built our reputation on a simple principle: quality that begins at the source. From stone cutting and selection to jewelry making and final finishing, we believe every detail matters.

Our journey began with one simple focus: excellent gemstone cutting.
From 2001 to 2014, we built our foundation in synthetic gemstone and jewelry production. During this period, we became one of the early gemstone factories in China capable of producing the Hearts and Arrows cut, a standard associated with precision, symmetry, and brilliance.
In 2015, we entered moissanite manufacturing and became one of the early moissanite producers in China, gaining recognition for product quality and custom jewelry craftsmanship.
Since 2018, we have continued expanding our product line by adding lab-grown diamonds and lab-created gemstones, allowing us to meet a wider range of customer needs across bridal jewelry, fashion jewelry, custom projects, and brand development.
With years of manufacturing experience and a growing product portfolio, Tianyu Gems has earned trust in the market for reliable quality, custom service, and responsive communication.

Manufacturing Strength
What sets Tianyu Gems apart is our background in both gemstone processing and jewelry production.
Because our foundation began with stones, we understand the technical side of jewelry from the inside out — including cut quality, proportions, brilliance, matching, and how gemstone characteristics affect the final piece. This expertise allows us to create jewelry that is not only visually beautiful, but also well balanced in structure, wearability, and finish.
Our manufacturing workflow covers key stages of production, including:
• stone sourcing and selection
• precision cutting and polishing
• CAD-based custom development
• sample making
• in-house jewelry production
• quality inspection before shipment
This integrated approach helps us maintain better consistency, clearer communication, and greater control over quality throughout the process. The current site also presents Tianyu as a one-stop custom jewelry manufacturer with in-house design and production support, which is an important strength to retain in the rewritten page

It is also about proportion, comfort, balance, individuality, and the emotion behind the design.

That philosophy continues to guide how we work — and how we grow.
