We offer free standard shipping worldwide. You can upgrade your shipping speed or add shipping protection at checkout. Please note that shipping times are an estimate, and your estimated shipping time begins after your ring has been crafted.

Narrow Bands (1mm-5mm)
For delicate bands, size using rings that closely match the width you plan to order.

If that’s not available, thin keyring-style sizers are generally reliable for this range.

Sizing Locally
If visiting a local jeweler, we suggest getting sized by 2–3 reputable shops and following the guidance above based on your chosen band width.

All of our rings are made to international sizing standards, with a precision tolerance of ±0.1 mm.

Returns & Exchanges
We accept returns and exchanges within 30 days of delivery, as long as your ring is returned in its original, unworn condition. Please email us for return instructions before sending your item back.

Custom Orders (Final Sale)
Custom pieces are final sale and cannot be returned or exchanged. “Custom” includes any modification to a listed design, such as changes to width, materials, stone selection, or the addition of engraving.

Completed services (including rush fees, engraving, and similar add-ons) are non-refundable and not eligible for store credit.

Cancellations

Orders canceled within 24 hours are eligible for a full refund. After 24 hours, cancellations may receive a 70% refund with a 30% restocking fee. For full details, please see our Cancellation Policy.

Design Rights
Staghead Designs retains the rights to all custom and commissioned designs and may feature them in our portfolio, marketing, or website listings.

Natural Variation
Because we work with natural materials, each ring will have its own unique color, grain, and character. No two rings are exactly alike.

All eligible rings will be engraved with our antler logo and metal type.

If you purchase a stone from the Staghead Mine, please note that loose stones are not shipped separately, and all sales are final.
