This 1950 half eternity ring is made of 18ct yellow gold and dates to the mid-century period. The design incorporates a half eternity band featuring five round cut light blue spinels interspersed with eight small accent diamonds in claw settings. The visible details include polished yellow gold settings, round facets on the blue spinels, and small clear diamond accents arranged in an alternating row along the band. The face measures 1.9 cm wide by 0.3 cm high and the whole piece weighs 2.2 grams. The ring is worn on the hand as a piece of fine jewellery. It suits daily wear or special occasions, functioning as a standalone band or stacked alongside other rings on the finger. The item is sized at UK size K with the option for resizing by a jeweller.

FAQs

A half eternity ring features gemstone settings positioned across the front half of the band rather than around the entire circumference. This design offers the aesthetic of a full eternity ring while allowing easier resizing and improved comfort for daily wear.

These rings are constructed from solid yellow gold, white gold, or platinum, frequently stamped with hallmark fineness such as 18ct or 750. They incorporate natural blue spinels set alongside brilliant-cut diamonds using claw or grain settings.

Authentic natural blue spinels are singly refractive gemstones that exhibit a clean, vitreous lustre without dichroism. Professional gemological evaluation using refractive index testing and spectrographic analysis confirms gemstone identity.

This type of band can be worn individually as a focal piece or stacked alongside a traditional engagement ring and plain gold band. The combination of blue gemstones and yellow gold creates a balanced contrast alongside other fine jewellery pieces.

Clean the band using warm water, mild soap, and a soft-bristled brush to clear debris from beneath the claw settings. Avoid abrasive chemicals and store the piece in a lined jewellery box to prevent metal scratches.
