This handmade ruby and diamond ring is made by Picchiotti in Europe especially for Hamilton. It can be crafted to fit a wide range of sizes, from 5.5 to 10.25. Its striking, architectural design comes thanks to an innovative and doubly precious combination of over 5 carats of vertically-set rubies rimmed by two rows of round diamonds. Fine rubies weigh over 5 carats and diamonds are 2.89 carats.
