The word “turquoise” is derived from the French pierre tourques (“Turkish stone”), acknowledging the widely held belief that the stone was first brought to the Western world by the Turkish in the 13th century. As unfathomably old as that makes turquoise seem, it’s actually even older than that; its earliest recorded use dates from the 5th century BC in present-day Iran. This very modern-looking stirrup-shaped ring actually dates to the early 20th century and features a lovely oval turquoise cabochon mounted in 18k yellow gold.
