Vintage 18K Gold 3.67 Carat Blue Sapphire 1.33 Carat Trillion cut Diamond Ring

An oval blue sapphire weighing 3.67 carats, royal blue and evenly saturated, in the center of this yellow gold ring from the 1990s. A trillion-cut diamond sits on either side, angling out toward the shoulders. The trillion is a triangular brilliant, cut shallow so its weight spreads across a wide face. The three-stone layout makes it a distinctive choice for an engagement ring, and the squared euro shank keeps it from spinning on the finger.
