We work with SCS certified recycled gold and precious metal alloys through a family-run casting house in New York City's Diamond District. Our house standard for diamonds is F+ color, VS clarity. We keep documentation of known-origin stones and can share it with you.

Our gemstones and diamonds are hand selected through reputable lapidaries. Diamonds for ceremonial rings are certified conflict-free under the Kimberley Process, and GIA certifications are available upon request.

A natural patina develops on gold over time. To slow it, remove your jewelry before bathing or swimming, before using household cleaning products, and before applying cosmetics or lotions. Harsh chemicals encourage tarnish.

A small polishing cloth removes the oils of daily wear and brings back the shine. It works on all metals and lasts for years.

Store your pieces in a pouch or a lined jewelry box, away from humidity and dust. It is good practice to take rings off at night.

If you are unsure how to care for a particular piece, write to hello@12thhousejewelry.com and we will guide you.

Our approach is simple. Use gentle dish soap and a soft-bristle toothbrush to lift any residue, then pat with a towel and let the piece air dry. Work over a bowl rather than the sink, so nothing is lost down the drain.

For enameled pieces, wiping with a soft cloth is enough.

If a piece is damaged, write to hello@12thhousejewelry.com for a repair consultation. We will evaluate the repair and guide you on next steps. Repair work can take up to six weeks, depending on the complexity of the repair.

Every piece is covered by a one-year warranty from the date of delivery. If a defect appears in the first year, we repair it without charge. Out of warranty, we still repair damaged pieces; fees depend on the extent of the repair.

Bespoke is a commission: a piece made for you. An existing design can be the starting point, personalized from your preference of precious metal alloy to the size and cut of its gemstone, or the piece can begin from an idea or a dream.
