Q & A

High-quality 316L stainless steel contains less than 0.05% nickel, passing ISO nickel release tests, making it safe even for sensitive skin. Providing test reports can strengthen credibility.

Stainless steel offers ​lifetime color retention (unlike plated jewelry that fades in months) due to ​IP vacuum plating. Offer “trade-in” services to add value.

Test with a magnet (real 316L is slightly magnetic), check laser anti-counterfeit codes, and request material certificates (e.g., SGS reports).

Cheaper versions may use ​201 stainless steel (prone to rust) or low-quality plating. Show cross-section comparisons to highlight differences.

Offer a ​1-year color guarantee and provide a care kit (polishing cloth + sealed bag). Mention it’s safe for showers/swimming.

Share factory smelting videos, material spectrometry reports, and offer a ​**”fake-refund-10x”** promise.

Tungsten’s ​extreme hardness (8.9–9.1 Mohs, near diamonds) and ​lifelong polish justify the cost. Highlight ​IP vacuum plating and scratch resistance vs. cheaper alternatives.

No—tungsten’s hardness makes resizing impossible. Offer ​exchange programs or discounts for new purchases.

Yes! Tungsten resists water, sweat, and chemicals. Caution against ​hard impacts (e.g., hammering) due to brittleness.

Low-quality alloys may crack. Stock ​certified tungsten carbide (WC) with ​cobalt binders for durability.

High-quality tungsten carbide (e.g., ​316L grade) contains minimal nickel (<0.05%) and is generally safe for sensitive skin. Provide ​allergy test reports (e.g., ISO 12870) for assurance.
