Vintage 10k Yellow Gold Blue Spinel Solitaire Ring Size 9

This is a vintage size 9 solitaire ring made of 10k yellow gold, featuring a 1.5-carat (give or take a point or 2 since it was measured in the setting) blue spinel as the centerpiece. The spinel is cut in a traditional style and is set in a high six-prong mount that elevates the stone, emphasizing its vibrant color. The ring is marked "10k" and "JJ" on the inside of the band, indicating its material and likely the maker. Notably, the spinel glows pink under UV light, a characteristic of some synthetic spinels. This piece dates back to the 1950s, reflecting the timeless elegance of mid-20th-century jewelry design.
