Product Features & Benefits:
- Nickel-Free Construction: Our rings are manufactured using specially selected stainless steel grades that contain no nickel, ensuring they are safe for individuals with metal allergies. This makes them perfect for earrings, nose rings, and other body jewelry applications where skin contact is prolonged.
- Precision 0.8mm Thickness: The uniform 0.8mm wall thickness provides a sturdy yet lightweight ring. It is thick enough to retain shape during shipping and daily wear, but thin enough to offer a delicate appearance. Whether used as a spacer, a stacking ring, or a component for charms, the consistent dimension guarantees a professional look.
- Wide Inner Diameter Range: With available sizes from 16mm to 20mm (including half sizes upon request), you can stock a variety without overcommitment. Each size is clearly marked and sorted, making order fulfillment fast and error-free for e-commerce operators.
- Multiple Surface Finishes: Choose from high-polish mirror finish for a classic jewelry look, brushed finish for a matte elegance, or plain matte for industrial or craft purposes. Custom finishes such as sandblasted, hammered, or colored PVD coating can also be arranged for large quantities.
- E-commerce Ready Packaging: We understand the demands of online sellers. Rings can be supplied in bulk packs (100 pcs per bag), individual poly bags, or with custom barcode labels and cards. Our packaging options help reduce your handling time and improve unboxing experience.
- Factory Direct Supply: As a manufacturer with 10+ years of experience, we control every step from raw material sourcing to final quality inspection. This ensures competitive pricing without compromising on quality. Our annual export value of US$2.5-5 million reflects the trust from global buyers.
Quality Assurance:
Every batch of rings undergoes strict dimensional checks using digital calipers and gauges. Surface quality is inspected under proper lighting for scratches, pits, or discoloration. Our ISO9001 certified management system ensures traceability and consistency. For larger orders, we can provide a Certificate of Compliance (COC) and third-party testing reports if required.

Frequently Asked Questions (FAQ)
1. What material is used in these rings? Are they nickel-free?
Our 0.8mm thick rings are made from stainless steel (typically 304 or 201), both of which are formulated to have negligible nickel content. We offer a nickel-free guarantee – they will not cause allergic reactions in most users. For extreme sensitivity, we recommend 316L stainless steel (available upon request).
2. What inner diameter sizes are available?
Standard inner diameters are 16mm, 17mm, 18mm, 19mm, and 20mm. We can also produce half sizes (e.g., 16.5mm, 17.5mm) and custom diameters within the 16-20mm range for volume orders. Please contact us with your specific needs.
3. Can I get a sample before placing a bulk order?
Yes, we offer samples for quality evaluation. Sample price is $1-2 per piece plus shipping. For serious buyers, sample fees can be deducted from the first bulk order. Please reach out to our sales team to arrange.
4. What is the minimum order quantity (MOQ)?
For stock sizes and standard finish (polished), MOQ is 500 pcs per size. For custom finishes or special packaging, MOQ is 2,000 pcs per variation. We are flexible for trial orders to help you test the market.
5. How are the rings packaged? Can I have my own logo on the packaging?
Default packaging is bulk poly bags with size labels. We also offer individual poly bags, cards, or blister packaging with your brand. Custom printing and barcode labels are available for large quantities. Please discuss your packaging requirements with us.
6. What is the tolerance on thickness and diameter?
Thickness tolerance: ±0.05mm. Inner diameter tolerance: ±0.1mm. Outer diameter is derived from ID + 2× thickness (nominal). We control these via precision tooling and 100% sampling inspection to ensure consistency across batches.
7. Do you provide certificates of compliance or test reports?
Yes, we can issue a Certificate of Compliance (COC) for each order. For external testing reports (e.g., lead content, nickel release), we can arrange a third-party lab test at an additional cost. Our factory is ISO9001 certified, which ensures process quality.
8. How long does delivery take?
For stock items (standard sizes and finish), delivery is 7-10 days after payment. For customized orders, lead time is typically 15-20 days depending on complexity. We ship via sea, air, or express from Shenzhen/Dongguan/Guangzhou ports.
