An elegant late 20th-century estate ring dating to the circa 1990s, centered with an oval-shaped 1.01 carat GIA-certified natural ruby of vibrant red color. The ruby is beautifully framed by a diamond halo totaling 0.46 carats, all set in a sculpted platinum mounting that reflects refined craftsmanship and timeless design.
