VERY GOOD: This antique old mine cut Diamond trilogy engagement ring is in sublime condition throughout. All of the Diamonds are securely set, free of chips, and are incredibly bright for Diamonds of this era. The fact that we see "CT" rather than "18CT" alludes to the fact that this ring was likely resized in its long life. Plus, the actual shape of the band is quite elliptical in shape, but we are confident that she will fit a UK size M.5 to N and US size 6 & 1/4 to 6 & 1/2.
