Type of Stone: Diamond
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.

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.

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.

Measurements: 8.35 x 5.31 x 4.02mm

Description: Clean, clear, oblong and uniquely stunning raw diamond. This raw diamond is actually freeform, but has an appearance like a dodecahedron. It is absolutely clean internally, and the surface of the stone has marking as if it was windswept sands in a desert. Everything about this stone was created by the earth alone, and was untouched by human hands. It would look gorgeous set vertically on the finger, and will elongate the hands of the wearer. a very special and valuable piece that is full of light.

Type of Stone: Diamond
Shape: Octahedron
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.

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.

Carats: 1.44
Measurements: 7.19 x 6 x 3.15mm
Color: Light champagne
Description: Rounded rhombododecahedral raw diamond that has an open face and flat countenance to it. This piece has a very unique aspect to it, where in one side, the crystalline structure did not grow linearly, leaving a depression, almost like a glacial lake in the shape of a diamond, with growth lines reverberating out of it. From the other side of the stone, this depression in the stone appears as a bright glowing light internally. Either way that you look at this stone, it is unique and full of light, a beautiful, sizable piece.

Type of Stone: Diamond
Shape: Freeform
Carats: 1.42
Measurements: 6.8 x 5.9 x 3.78mm
Color: F, near colorless
Description: This raw diamond started growing as a certain shape, most likely a triangle, but then at some point in its many millions of years of growth, it decided to make a change, and turned into somewhat amorphous, flowerlike shape that is covered in natural facets along all its edges, refracting light in various almost random seeming directions. It's clean and clear and elegant, and it looks like it just decided it wanted to be unique, and so it created for itself this one-of-a-kind shape that will look absolutely stunning in any of our rough diamond ring options.

Description: This green, clean and amazing diamond should get snatched up pretty quickly, it's a very rare and very desired type of stone. The green is a nice concentrated, natural color that rarely appears on rough diamonds like this. The shape is almost oval, and will set absolutely beautifully. Take a look at the videos, this one is a stunner.

Type of Stone: Diamond
Shape: Freeform/Macle
Carats: 1.57
Measurements: 5.74 x 6.4 x 4.49mm
Color: G-H
Description: This is a really cool raw diamond. If you look closely, especially from the "underside" of this diamond, you can see that the original crystalline structure of the stone is a triangle. Ordinarily, these shapes grow pretty linearly, into a thicker triangle over time or eventually an octahedron. However, in this stone, the triangular crystals did grow upward from their base, but simultaneously, on all straight edges and in the corners, new crystalline structures grow outward in triangular shapes as well, creating a six-pointed star shape. This is really unbelievable and a joy to simply look at and observe. The top center of the crystal is again a triangle, but has a little uniqueness in its shape as well, almost like a teardrop at the heart of the stone. The center of this stone is clean and clear, and it s a true gem of a rough diamond.

Color: FG with slight green undertone
Description: Gorgeous oblong dodecahedral shaped raw diamond. What makes this stone completely unique is that in dodecahedrons, the growth lines are not usually shown and the crystalline structure is quite linear, however, in this stone, as you can see from the surface patterning, there is a very clear growth spectrum, of one layer on top of the next. It's really a sight to see, and these growth lines have the benefit of refracting light son that this stone really glows!
