Type of Stone: Diamond
Shape: Octahedron
Carats: 0.96
Measurements: 4.62x4.59x5.85mm
Color: Near Colorless, D/E
Description: Beautiful, otherworldly rough diamond octahedron. This stone has smooth terminations and lines that grace the stone in each direction reaching from point to point ever so gently. We see a trigon at the center of one of the "windows" which is always a find on a smooth rough diamond like this. The coloring is excellent. This stone comes off as sophisticated, gentle, smooth and unique.

Type of Stone: Diamond
Shape: Octahedron
Carats: 0.92
Measurements: 4.91x4.59x5.1mm
Color: Near Colorless, D/E
Description: Stunning rough diamond octahedron with near perfect coloring, shape and clarity. The diamond carries the light in such a luminous and sophisticated manner - it really is a showstopper, such a lovely piece. One end of this octahedron has an interesting particle of carbon matter that was trapped in the stone during its original formation millions of years ago beneath the earth's crust. When observed from different angles of the stone, the speck can be seen as a single point, or even as a semicircle perfectly surrounding one of the points of the stone. Depending on how you choose to set this stone is how you will see the perfections and imperfections of this stone intertwined.

Type of Stone: Diamond
Shape: Octahedron
Carats: 0.87
Measurements: 5.49x4.23x4.87mm
Color: Colorless, D
Description: Stunning oblong and bright white octahedron. This one is full of a white light that sits both internally and close to the edges of the stone. It's clean and clear throughout its heart, and the surface of the stone is nice and smooth. This octahedral raw diamond is not sharp, which makes it a very comfortable piece for long term wear, while at the same time, appearing sharp and architectural as you would hope. A lovely piece with nice gentle surface patterning too.

Type of Stone: Diamond
Shape: Triangle/macle
Carats: 1.02
Measurements: 7.02 x 6.79 x 2.85mm
Color: D - brightest clearest white color
Description: This triangular raw diamond is out of this world amazing. First of all, it is incredibly proportional, and on top of that proportionality, the natural structured lines of the stone that make up its "windows" meet almost perfect at the heart of this stone, creating a gentle peak with three triangular windows descending lightly at each angle. The effect is stunning with proportional bursts of light emanating from each side. On the outside of the stone, close to the edges are wisps of coal that were trapped in the diamond during its formation, they for whatever reason didn't become diamond crystal like the rest of the diamond, but rather became these irresistible markings of its creation millions of years ago, stamping this diamond with a completely unique appearance that will never be replicated again. This diamond has clarity and transparency, and is very smooth and gemmy - perhaps it spent a large part of its formation in water. Beautiful for any piece!

Measurements: 6.82 x 6.21 x 3mm
Color: D-E - bright white, near colorless
Description: Wonderful unearthly macle/triangle raw diamond that has some awesome markings within to make this a very unique and special piece. First, along the edges, ever so lightly are little wisps of carbon that were trapped during formation and did not become crystals, they give the edges of the stone a unique and slightly earthly look. Then, the surface of the stone has some beautiful trigons etched into it naturally due to the natural growth of the diamond crystals during its formation. This stone is clean at its heart and is very transparent. It's a proportional stone that will look amazing in a unique setting.

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.

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.
