Type of Stone: Diamond
Shape: Triangle
Carats: 1.40
Measurements: 7.18 x 6.02 x 3.32mm
Color: Champagne gold
Description: Champagne tinted smooth and clean macle that is, unfortunately, broken on one end. Due to the broken nature of this stone, it should be creatively placed in a setting that either complements the breakage as a metaphor, with a cluster of stones by the breakage, or simply in a bezel setting. The other alternative to dealing with the breakage is cutting and polishing the stone - and there are various options here - a full cutting of the stone to a final finished piece, or simply polishing the broken area. For an extra fee, we can take care of the cutting and polishing services. The rest of the stone is a luminous and gemmy champagne natural raw diamond. So, be in touch when you see this stone and it appeals to you, and we'll come up with something creative.
