Related questions

Can I request a quote for a single custom piece?

Yes. We support one-piece custom orders for personal clients, so a single custom jewelry project can also be quoted and produced based on your requirements.

Do you provide wholesale pricing?

Yes. Tianyu Gems supports wholesale inquiries, OEM/ODM projects, and business orders with flexible quantities. If you are sourcing for retail, wholesale, brand development, or collection launch, we can recommend the most suitable quotation method based on your order type and product scope.

What is your MOQ?

Our MOQ is flexible. For personal custom jewelry projects, we support one-piece custom orders. For business and OEM ODM jewelry orders, quantities can be discussed based on the design, materials, and production plan. This flexibility allows us to serve both individual buyers and wholesale clients.

Do you accept sample orders?

Yes. After design approval, we can move forward with sample making before larger production. Samples typically take around 7–10 days depending on the project. This is a common step for brands and wholesalers developing new moissanite jewelry or lab grown diamond jewelry collections.

Can I start with a small trial order before bulk production?

Yes. Many clients begin with a sample or small trial order to test quality, finishing, and market response before scaling up. This is especially helpful for new brand launches and private label jewelry projects.

Do you offer custom jewelry manufacturing?

Yes. Custom jewelry manufacturing is one of our core strengths. We support a broad range of custom categories including rings, earrings, pendants, necklaces, bracelets, bangles, bridal sets, men’s jewelry, and personalized gift jewelry.
