Description
The stone has an even, warm color without visible banding – the classic carnelian vibe. Commercially, it's still chalcedony, often called red agate.
The wide oxidized crown creates a strong contrast and enhances the "vintage" feature. Hand-stitched edges around the stone add rhythm.
It complements leather, denim, and wool. One ring that "closes" the look and enhances it with color.
In your shop description, rotate the names: carnelian / red agate / red chalcedony – honestly, sensibly, and effectively for search engines.
