The elongated face follows the finger, giving a mountain ridge or winding valley a quieter setting. Choose it for someone who prefers a smaller ring with a personal story. ### Classic Signet A custom signet ring with the hills and valleys of a place that matters to you. The balanced signet face gives your landscape room to show its contours. Start with a favourite summit, the place you met or a stretch of home, then adjust the area and terrain height in the studio. ### Statement Signet A bold sterling silver signet ring shaped by your chosen landscape. A broader signet face makes the terrain the focus. Choose a dramatic mountain range or a landscape with a strong silhouette. This Statement style is offered in sterling silver in the current studio collection. ### Subtle Disc A small round terrain ring that turns a meaningful place into a personal keepsake. The compact circular face frames a small patch of landscape above a slender band. It is a considered starting point for a first custom ring or a gift for someone who likes understated jewellery. ### Classic Disc A round custom ring with a raised terrain surface from your favourite place. The circular face puts your chosen terrain on display from every side. Frame a summit, coastline or valley, rotate it to find the composition you like and compare silver with the available gold alloys. ### Statement Disc A large round sterling silver ring for a landscape with a story worth telling. The widest disc in the collection gives the terrain a generous circular frame. It suits someone who enjoys a prominent ring and wants their chosen landscape to be the centre of the piece. This Statement style is offered in sterling silver. ## Agent purchase boundaries The HTTPS API uses the buyer's own server-issued session cookie and checks ownership.

The server checks recipe, quote expiry, fingerprint and price before creating hosted Stripe checkout. Do not treat a checkout link or success redirect as proof of payment: read the order's webhook-confirmed paymentStatus. Checkout availability can be disabled.
