Shape: Rhombododecahedron
Carats: 1.46
Measurements: 6 x 5.94 x 4.32mm
Color: EF with slight lemon-lime undertone
Description: A beautiful blossom of a raw diamond, this rough diamond dodecahedron has a matte surface which gives it an otherworldy glow! The lines on the surface of the stone create a beautiful pattern that not only is pleasing to the eye, but plays with the light, refracting light both on its surface, internally and outwards. This stone will look amazing, and will set nice and smoothly in the ring.

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: Octahedron
Carats: 1.40
Measurements: 7.19 x 5.78 x 5.0mm
Color: EF with slight lemon-lime undertone
Description: Amazing rectangular and proportional raw diamond octahedron. This one has an overall slightly oblong structure which allows you the flexibility in choosing if you'd like to set it vertically or horizontally along the finger, both are beautiful and just a matter of taste and design. This stone has trigons on its surfaces that are ever so delicately naturally grown into the crystal there. The surfaces are near perfect triangles and it is a very well structured stone architecturally. the terminations and lines on the edges of the stones are straight and strong while not being too sharp in appearance or feel. this is a really special and classic type of stone with its own unique aspects, a beautiful raw diamond for most ring styles.

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: 1.24
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: 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 : 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.

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.
