Bloodstone — a dark green chalcedony scattered with vivid red jasper inclusions — has been the preferred stone for seal engraving since antiquity. Its hardness takes a crisp impression in wax, its dark ground provides excellent contrast for an engraved device, and its association with heraldry and signet rings runs unbroken from the ancient world through to the present day. The oval head of this ring, 15 × 12.5mm, is unengraved and ready to receive initials, a monogram, or a family crest.

The ring is made in 18ct yellow gold by Charles Green — one of Birmingham's most distinguished signet ring makers, whose maker's mark C.G. is a reliable indicator of quality and craftsmanship. The shoulders are finished with reed detailing, the fine parallel grooves that run along the length of the shoulder and give the ring a refined, architectural quality without competing with the stone. At 8.7g the ring has a satisfying weight on the finger.

Hallmarked 18ct gold; maker's mark C.G. (Charles Green). Ring size R (UK).
