Type of Stone: Diamond
Shape: Octahedron
Carats: 1.62
Measurements: 7.3 x 7.5 x 6.00mm
Color: D - brightest clearest white color
Description: This here is the nicest, fanciest raw diamond we have ever had on inventory. A rough diamond that is clean and clear - as you can see from the photos and videos below. As a single stone, it has a great deal of value in and of itself, it's quite a rare piece, and even moreso, if placed in a unique setting, this will make an absolutely spectacular ring. First of all, its structure architecturally is excellent - the stone is proportional but not too perfect, the points are strong and even yet not too sharp, the heart of the stone is clean and clear and you can look into all the transparent edges to see just that. Now, the final thing that makes this glorious octahedron even more special is the white trigon internal crystal that floats gently at the heart of the stone. This is a very unique "stamp" to this stone that makes it so that no other stone will ever be similar. Now, here's what makes this stone really spectacular - on several edges and internally, there is a natural crystal structure that appears to float freely in the stone and has the shape of a star. This raw diamond that originally came from a star itself millions of years ago is dotted with a couple little star patterns within. It's just spectacular and we absolutely love this piece.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.67
Measurements: 7.24 x 5.68 x 5.63mm
Color: D - brightest clearest white color
Description: The most spectacular of our raw diamonds in our collection at the moment. This raw diamond is an almost perfectly proportional octahedral shape with excellent lines and terminations. The interior is clean and clear of any inclusions, and the color is a colorless bright white with a shine and refraction ability that gives light everywhere. This stone is very valuable in and of itself. Now, if you look at it under a microscope, you can see the the surface actually has a bit of patterning that does not appear to the naked eye, and the patterns are stunning! Almost like ancient etchings on cave walls, except they are made purely by the growth of the diamond crystals themselves, they are triangles of varying sizes called trigons, and their appearance is as if the stone has drawn a mountain range on its own edges. Really an amazing piece.

Description: Beautiful bright and elegant rough diamond octahedron. This one has such an intensely beautiful structure with clean and clear lines and windows into its clear heart. This raw diamond is really a specimen to behold and it carries its beauty and light so clearly. At the heart of the stone is a floating trigon - part of its natural crystalline structure, not an inclusion but rather a floating crystal, it's really special and beautiful and reminds us that we're all floating crystals in this place we call earth.

Measurements: 7 x 5.08 x 5.79mm
Color: D - brightest white color
Description: Amazing octahedron that is completely colorless and emits a bright white light. This raw diamond octahedron is unique in its surface patterning - the geometrical lines that were naturally created on its surface during its crystal's formation. The surface patterns are concentric triangles that don't exactly match up with one another creating the most stunning effect! The earth is truly the greatest artist. This is a sparkly bright white piece and it's going to look amazing once set.

Color: Near Colorless, D/E
Description: Oh wow, this stone is incredible. I write these descriptions one by one as I sit in my office, and I came upon this stone and just said, wow. It's big, it's proportional, it's bright white, it's clean and and clear but not too clear if you know what I mean (like it's not glassy, it's diamondy), and there is this awesome effect on the "windows" of each side. If you look closely, the windows have etchings of what appear to be mountains, almost like ancient cave etchings, but here, made by the earth over the formation of this diamond for millions of years. This is going to be an expensive stone, and it completely justifies its value. This is a very very nice piece.

Description : This proportional and amazing golden octahedral raw diamond is quite the specimen. It has a wonderful size, shape, and clarity. The color is out of this world - sunny and golden, and full of light. We love these perfectly structured octahedral raw diamonds because it shows how natural structure in diamonds can also be perfect. This will set beautifully and amazingly in any ring and will be a top of conversation, this stone will not go unnoticed!

Shape: Dodecahedron and Octahedron
Carats: 1.72
Measurements: 6.91 x 5.5 x 5.4mm
Color: E - white with a slight natural coloring that is difficult for the eye to detect
Description: This is an interesting and stunning piece. At different angles, the structure of this stone appears to be either octahedron - like a stacked pyramid shape - or like a dodecahedron - which has diamond shaped "windows" on its surface. So, the surfaces of this stone are both triangular and diamond shaped, giving this stone an almost magical appearance. It is almost perfectly clean with one small wisp-like inclusion on one edge that will be covered most likely when set, though it could be set in a manner that the tiny inclusion is laid bare - for intrigue. The surface of the stone has geometric lines on it, gently outlining the shape of the windows themselves. This provides a multidimensionality to the appearance of the diamond - giving it shine and sparkle as well. This will set beautifully no matter which way you choose to set it, and as a rough diamond on its own it's a very special specimen.

Description: This is an amazing rough diamond! It is bright and sparkly and full of light and clear and perfectly colored. You cannot go wrong with this stone. From different angles it appears to be a dodecahedron, and from other angles octahedral, so the structure is also unique.

Carats: 1.17
Measurements: 6.3 x 5.06 x 5.01mm
Color: D-E - bright white, near colorless
Description: A proportional and excellent raw diamond octahedron that will really wow. This type of octahedron always seems to have "diamond experts" tell us that they were cut by human hands to look like this, and we find ourselves trying to explain to them that this is the natural shape of raw diamonds and that the earth created them just so. The perfection of the windows and the proportionality of the stone really confuses gemologists who don't have a lot of experience with rough. You may, when wearing this stone, come across the same conversation with others. This beautiful piece you can be absolutely assured, was cut by the earth alone - grown just as is and taken from the earth in this clean, clear, beautiful way. It's bright and full of light, and will look like a classic rough diamond octahedron in your ring.

Measurements: 6.7 x 6.35 x 5.2mm
Color: Colorless, D
Description: This has to be one of our favorite types of raw diamonds - the perfect octahedron. This is, believe it or not, the perfectly natural formed shape of this diamond - no human hands have done any modifications or cuts to this stone. It is proportionate, clear, clean (except the one white seam you can see in the photos), and bright white. The surfaces of each triangular window are smooth and clear, allowing you to easily view the center of the stone. We think this diamond is even more perfect because of that one white seam that has an effect that allows you to see it was naturally formed by the earth (lab diamonds do not show this type of internal patterning), plus it just looks really cool.

Description: Beautiful, classic looking rough diamond octahedron with a clean and clear center. This stone has a nice glow to it that provides light both internally and on its surface. The windows on this stone are nice and clear, giving you vision into the center of the stone which is clean and clear with some microscopic wisps near the surface if you're looking with a loupe, of course. This will set like a classic octahedron, similar to the ones you see in many of our styles on our site. Though it is "classic" it is still completely unique - no other rough diamond will ever be the same as this one.

Carats: 1.40
Measurements: 5.89 x 7.21 x 5.4mm
Color: D-E - bright white, near colorless
Description: This is the coolest raw diamond we've seen in a while. At first glance, it appears broken. But then, when looking closer, you will realize it is not broken at all, in fact, the crystalline structure of this octahedron just didn't finish its pointed edges as an octahedron normally would. Instead, the crystals grew into multiple points, creating from far away a look of the edges being flattened out. But, on closer inspection, the edges of this raw diamond are a mountain range of unique triangular crystalline structures. This unique structure has the added benefit of allowing this octahedron to naturally avoid the sharp edges. The interior of this stone is clean and clear, and has a very cool trigon floating internally. Watch the video of this stone, it really gives you a nice idea of this unique and special piece.

Color: Colorless, D
Description: Luminous, proportional, clear and bright rough diamond octahedron. This one is a nice size and carries the light beautifully. Another spectacular aspect to this diamond is its architecture - each "window" is a triangle that allows you to peer into the center of the stone. The triangles have a natural frame around their edges, which is a slight crystalline structure that is really a concentric triangle at every corner.There is only one white seam in the center of the stone, otherwise it is clean and clear and without blemishes. Really a valuable and beautiful piece of diamond.

Carats: 1.39
Measurements: 6.64 x 5.81 x 4.82mm
Color: E with every so slight light green/lime undertone
Description: This is a stunning raw diamond. It's an octahedron, but naturally sits on one of its triangular edges, so it lays bare one of its clear windows right into the heart of the stone. One of the most amazing things about this diamond is that if you look very very closely into that window, you will see that there are two tiny trigons floating internally, almost undetectable. These are not inclusions, they are part of the diamond's natural crystalline structure and usually appear only on the surface of a diamond. Here they are at the heart of the stone, in a very rare pattern. This diamond has a beautiful golden and white light that it emits from all of its edges, a white interior, and a bit of surface patterning alone its terminations, adding even more light to the stone. A very special raw diamond and will set very fancy into any ring.

The surface patterning adds sparkle and extra refraction of the light source. Within the stone, it's very clear and has one inclusion that is awesome to look at. The inclusion is a ring of carbon compounds that was trapped within the diamond during formation. From some angles it looks like a point, and from one particular angle it appears as a square, perfectly centered with one of the points of the octahedron jutting out from it. It's a lovely and interesting stone, both architectural, but also a bit earthy, while also being the brightest white a stone can possibly be.
