Type of Stone: Diamond
Shape: Octahedron
Carats: 1.41
Measurements: 6.76 x 5.12 x 5.41mm
Color: E - white with a slight natural coloring that is difficult for the eye to detect
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.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.25
Measurements: 6.71 x 6.71 x 5.15mm
Color: Colorless, D
Description: An amazing, bright and colorless rough diamond octahedron that has an awesome natural architecture, amazing terminations, bright, clean triangular windows into the stone's heart, and the coolest part - you can see a gentle swoosh at the center of the stone which is actually a structure in the crystal's formation created by the diamond itself. This little microcosm of creation would look amazing in an of our ring settings.

Type of Stone: Diamond
Shape: Dodecahedron
Carats: 1.40
Measurements: 6.6 x 4.99 x 5.23mm
Color: D-E - bright white, near colorless
Description: This is such a classy and beautiful dodecahedral raw diamond. The stone is nicely proportional, but also a little tiny bit disproportionate in just the right way, so that it is obvious it was formed by the earth. The stone has an obvious center window that would face upward, and the lines on that surface are vertical, meanwhile, on the windows that connect with the center window, the surface lines are horizontal, and the effect is as if it was sketched so that each surface would stand alone but also come together in a magnificent and unique tapestry of diamond that is extremely pleasing to the eye. From this stone you can see my passion for raw diamonds. This one, though it is colorless and clean and clear throughout, holds the light with an ever so golden shine and the effect is out of this world.

Type of Stone: Diamond
Shape: Octahedron
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.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.24
Measurements: 5 x 5.4 x 6.6mm
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.

Type of Stone: Diamond
Shape: Octahedron
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.

Measurements: 6.93 x 5.0 x 3.65mm
Color: E, bright white and nearly colorless
Here's a completely unedited video of this stone in natural sunlight:
Description: Gorgeous offset dodecahedron that is a bit oblong and uniquely structure. The center "window" into the stone reveals a clean and clear center. The stone has a nice deep glow to it, and a slight silver undertone on the edges that gives it almost otherworldy appearance. It's smooth and shiny, probably because it's an alluvial diamond, meaning it was formed or at least sat under water for millions of year.

Type of Stone: Diamond
Shape: Dodecahedron/Octahedron
Carats: 1.25
Measurements: 5.45x4.8x6.22mm
Color: E-F, with slight lemon-lime undertone
Description: Lovely and interestingly shaped octahedron with one dodecahedral side. This raw diamond has a unique depth to it since it has a very clean and clear aspect but also a slight lemon-lime undertone that adds intrigue. The light it gives off is truly white, and the interior of the stone is also a bright white, it is the exterior that holds the faint coloring. The interior is clean and clear with a few wisps of trapped matter from it formation, and the stone has a slightly offset but architectural lok to it giving it yet another unique aspect. It's a beautiful piece and will look amazing on the hand.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.25
Measurements: 6.15x6.24x4.98mm
Color: E
Description: This gorgeous rough diamond octahedron is very proportional, clean and clear, and holds a bright white light. The surface has a very slight natural brushed texture to it which gives this stone a bit of a matte look to it - it's beautiful. The interior is clean and clear and it's just bright white and such a nice proportional shape.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.1
Measurements: 5.12x5.89x4.81mm
Color: Colorless, D
Description: This is such an interesting and luminous octahedral raw diamond. On the outside, this stone has quite a bit of crystalline structure creating natural surface patterns through the many faces of the stone, these patterns give multidimensionality to an already multidimensional piece, but they also carry the light on the surface of the stone creating a very sparkly effect that is otherwordly. Internally, this rough diamond is clean and clear and perfect. We think it looks like an etching of snow covered mountains.

Type of Stone : Diamond
Shape : Freeform/rectangle
Carats : 1.04
Measurements : 6.45 x 4.2 x 2.77mm
Color : Faint lemon lime
Description : This is our first ever rectangular diamond on inventory. This is an intriguing rough diamond. The crystalline structure actually appears to have naturally welded two triangles to one another - which would be a much more natural crystalline structure for a rough diamond, but makes a rectangle possible. The stone is super clear through its center, but if you flip the stone on its side, you will see a seam of carbon running from one end to the other, perfectly centered. This will not be visible from the top of the setting, but rather if you were to turn your hand to the side and it was set in a ring with prongs It's very cool, and looks like the seams created by volcanic activity in rock formations today.

The Stav is a three-stone raw diamond and rough gemstone engagement ring with a conflict-free diamond channel band. The way the three main stones is set is natural and unique and contrasts beautifully against the sparkly cut diamonds that surround the band. We named this ring Stav, which in Hebrew means autumn, because we feel that it has the multicolored and rustic effect of falling leaves in the angled white autumn sunshine. It's a scene of a part of a year that echoes specially in all of our souls. In the photos, we've used a larger center freeform shaped rough diamond with two gemstones alongside. You are welcome to choose any sidestones to place in this ring - white rough rough diamonds, purple amethysts, red garnet, green peridot, blue aquamarine, etc. - and it would look amazing! The price includes the cost of the sidestones that you will choose together with us after your purchase.

Type of Stone: Diamond
Shape: Octahedron
Carats: 1.02
Measurements: 5.91x4.69x4.68mm
Color: Colorless, D
Description: Bright white octahedral rough diamond with beautiful concentric triangle surface patterning through the stone. 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.

Type of Stone : Sapphire
Cut : Round
Weight : 1.26 carats
Dimensions : 6.73 x 5.42 x 3.42mm
Description : This is an absolutely extraordinary sapphire. It has a multicolored aspect to it with blues, whites, a bit of gold and an undertone of green. The stone is beautifully cut and polished, and it is 100% natural and untreated. The sapphire was mined from our partner mine in Sri Lanka and cut on premises at their family's cutting facility.

Type of Stone : Diamond
Shape : Maccle/triangle
Carats : 0.90
Measurements : 5.72 x 4.46 x 3.96mm
Color : E - white with a slight natural coloring that is difficult for the eye to detect
Description : A lovely rounded triangular shaped raw diamond with a slightly oblong angling to it. This triangle rises up to its point at the center, and has a nice smoothness to it that makes it appear almost waterlike on its surface. It's very clean and clear with ever so slight wisps of matter trapped in the stone from millions of years ago - the wisps are at the stones perimeter and the center is clean and clear - this provides for an amazing framed effect at the center of the stone. We like this type of stone that is both the most spectacular and shiniest type of fancy raw diamond but that also has those wisps of matter to show that it is still a natural diamond, formed by the earth.
