This Edwardian boat ring dates from 1960 and takes the form of an 18ct gold navette cluster. The piece is set with a row of five round cut blue sapphires, each weighing 15 points and totalling 0.75ct, which are encapsulated by a halo surround of fourteen brilliant cut diamonds totalling 1.32ct. Claw settings secure the gemstones, and the diamond weight is marked on the inside of the band alongside rubbed hallmarks that test for 18ct yellow gold. The face of the ring measures 0.8 cm high, 2 cm wide, 2.4 cm deep, and the entire piece weighs 5.4 grams. Designed in a timeless style, this ring is suited for formal wear or everyday accessorising as a signature jewellery piece. It slips easily onto the finger for evening events, dinners, and special occasions, adding a flash of silver and blue to modern outfits. The durable gold band and secure claw settings make it practical for regular personal wear, while the compact dimensions allow for comfortable storage in a jewellery box or display on a dressing table when not in use.

FAQs

A boat ring, also known as a navette-shaped cluster ring, features gemstones arranged in an elongated, oval or marquise-like setting reminiscent of the hull of a vessel. Popular in the late Victorian and Edwardian eras, this design maximises finger coverage and gemstone brilliance.

Antique cluster rings are commonly crafted using 18ct yellow gold, white gold, or platinum settings. Natural deep blue sapphires are frequently paired with round old-cut or brilliant-cut diamonds held in claw or grain settings.

Authentic period pieces often feature hand-cut gemstones, intricate under-gallery metalwork, and hallmark stamps indicating gold purity and maker details inside the band. Inspection under magnification typically reveals characteristic natural inclusions within the sapphires.

A sapphire boat ring can serve as a central statement piece worn on the index or ring finger, or paired alongside simple gold bands to complement both everyday tailoring and formal eveningwear.

Clean the jewellery using warm water, mild liquid detergent, and a soft-bristled brush to clear residue from behind the settings. Store the piece separately in a fabric-lined box to prevent diamonds from scratching adjacent metals or stones.
