3.00 Carat Antique Three-Stone Diamond Ring A close family of old mine-cut diamonds, together weighing 3.00 carats, sparkle happily from a straightforward gypsy-style mounting. The three diamonds - 1.55, .75 and .70 carats respectively - display a bright and sunny yellow-tinted hue, and if removed from the mounting would most likely be classified natural fancy yellow or light yellow color. Sparkle times three! $13,750.00
