1970 Diamond Signet Ring (Star-Set Bark Finish)

A striking piece of mid-century craftsmanship, this rectangular diamond signet ring captures the bold geometric styling of the 1970s. Crafted in solid 9ct yellow gold, the ring features a distinctive block-link shoulder design with a finely textured bark finish — a hallmark of the era’s retro aesthetic.

Set with a natural round-cut diamond (approximately 0.02 carats) in a star-shaped setting, the ring combines sharp lines with subtle sparkle, making it a standout vintage design for collectors or everyday wear.

Weighing 3.6 grams, the ring’s 13mm x 7.5mm rectangular face gives it a confident yet refined presence.

Fully hallmarked with the SMO sponsor’s mark, London Assay Office, and date letter “P” for 1970, confirming its authenticity and vintage provenance.
