◆ QUESTIONS
Our pieces are crafted from hypoallergenic surgical-grade stainless steel with a bonded 18K gold or rhodium PVD coating. This gives the look and feel of fine jewelry at a fraction of the price — and the finish is rated to last 5–10× longer than traditional plating.
Yes. Every piece is waterproof, sweatproof, and skin-safe — designed for daily wear including showers, workouts, swimming pools, and the ocean. We do recommend avoiding harsh chemicals (chlorine concentrate, bleach, perfumes sprayed directly on jewelry) to preserve the finish over the long term.
No. Because the base metal is surgical-grade stainless steel (not brass or copper) and the gold/rhodium coating is bonded via PVD, there's no reaction with skin or sweat that causes discoloration. Our lifetime color warranty covers you if it ever does — we'll replace it free.
Open the size guide link under the variant picker on this product page. You'll find charts for rings (EU/US/UK + inside diameter), bracelets (wrist circumference), and necklaces (chain length to neck position). If you're between sizes, we recommend sizing up for rings and bracelets.
US orders arrive in 4-7 business days. EU orders in 3-6 business days. Rest of world, 7-14 days. Orders placed before 3 PM local time ship the same day. Free worldwide shipping on every order — no minimum.
60-day return window from the date of delivery. Pieces must be unworn, in original packaging. Start a return via our returns page — we'll issue a prepaid label and refund to your original payment method once we receive the item (usually within 3 business days of arrival at our warehouse).
The warranty covers manufacturing defects and loss of color on the PVD coating for the lifetime of the piece — we'll repair or replace free. It doesn't cover damage from impact, loss, or extreme conditions (saltwater over months without rinsing, for example).
