Type of Stone: Diamond
Shape: Triangle/macle
Carats: 1.03
Measurements: 6.71 x 6.4 x 3.12mm
Color: F with a slight green-silver undertone
Description: Lovely triangular raw diamond with a unique structure that is basically concentric triangular diamond crystals that grew one on top of the other. The top of the stone has a triangular window where the growth terminated. It's a piece of natural art. The stone has a couple inclusions on the edges that give it an unearthly look, these inclusions are trapped matter from beneath the earth's mantle millions of years ago, and they float so lightly along the edges, they make the piece look really special. The diamond itself is very smooth and has a nice white shine to it, internally at its heart it is clean and clear and you can peek through the top window to see right through it. The edges are smooth and there are no hard points so it will be worn comfortably. We love that the lines on top of the stone create a proportional and gentle sign of peace.

Type of Stone: Diamond
Shape: Triangle/macle
Carats: 0.88
Measurements: 6.1 x 5.55 x 3.12mm
Color: D-E - bright white, near colorless
Description: Lovely raw diamond macle or triangle. This one looks very gemmy, which basically means that it is smooth and glows and has a very fancy look to it. It has a white light both internally and refracts that light towards its points and outwards as well. This stone has concentric triangular surface patterning which is really nice, and the way the crystal grew is one smaller triangle on top of the other, so the shape of the stone has an almost pillow aspect to it. It's very nice and will set beautifully.

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.
