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.

Approximate details on each stone
Carats : Average 1.25 carats
Number of Stones : Total in the parcel is 290, but you choose how many you'd like us to pick for you
Measurements : Approximately 5-9mm each
Description : This parcel of rough diamonds is downright awesome - they are white and sparkly and shimmery. Some have a bit of a silver undertone to the shimmer which makes them even more otherwordly. The shapes vary but are generally round or have a octahedral model to them. The surfaces on each stone are different, some are more indented than others, each providing different plays with the light. They could be identified as boart, but they are also cuttable and so would be considered very high quality boart. This parcel is unusual in the high quality of the stones at this price point.
