Frequently asked questions

FAQ

The questions we get most often. If yours isn't answered here, write us — we'd rather you ask than guess.

What metals do you use?

Our pieces are made from solid 925 sterling silver or 18k-gold-plated stainless steel cores. Stones are lab-grown zircon and freshwater pearl unless otherwise noted on the product page. We don't use brass under our gold plating.

Will the gold plating tarnish?

High-quality 18k-gold-plated steel is significantly more durable than gold-plated brass. With reasonable care (see below) you can expect 12–24 months of daily wear before the plating starts to show wear at high-friction points. Our lifetime plating warranty covers major colour issues — significant discoloration or fading — and resolves with a replacement or store credit, not a cash refund. Normal wear, scratches, pearl discoloration, and damage from chemicals or improper storage are not covered.

Is the jewelry hypoallergenic?

Our 925 sterling silver and 18k-gold-plated stainless steel pieces are nickel-free at the outer surface and considered safe for most sensitive skin. If you have a confirmed nickel allergy, please write us before ordering and we'll confirm the exact composition of the piece you're considering.

How should I care for my pieces?

Take rings off before applying lotion, perfume, or sunscreen. Pat dry after showering or the gym. Store each piece in its Marbles dust pouch (or any soft cloth pouch) away from direct sunlight and other jewelry. Avoid chlorinated pools and saltwater for plated pieces.

Do you offer ring sizing?

Where a piece is available in multiple sizes, you can pick at checkout. We don't currently offer custom resizing. Sizing mistakes are not eligible for refund or exchange — please measure carefully, or email [email protected] before ordering and we'll help you pick.

Where do you ship?

Worldwide. See our shipping page for rates and estimated transit times.

Where are your pieces made?

Designed in California, manufactured by partner workshops in southeast China that specialise in fine jewelry. Each piece is inspected before shipping.
