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.

Certifications: This stone was traded between borders completely in keeping with the Kimberley Process and is therefore conflict-free and does not finance violence by rebel groups seeking to undermine legitimate governments anywhere on earth.
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.

Shape: Dodecahedron
Carats: 0.88
Measurements: 6.5 x 5.1 x 3.32 mm
Color: I-J
Description: Very pretty and glowing dodecahedral raw diamond. It has a clear, white center with the edges of a more champagne hue, adding uniqueness and depth to this already amazing specimen of ancient earth. The stone is smooth and holds the light on its surface. And its oblong yet flat shape lends another level of wearability that will look lovely in any of our settings.

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 from the options below.
Please allow 7-8 weeks to receive your ring. If you need it to be rushed or customized, please contact us directly at info@therawstone.com.
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.

The Gefen ring is a custom handmade engagement ring inspired by natural vines weaving amongst themselves. One of the twists is inlaid with tiny conflict-free cut diamonds on the top half of the ring. The band is delicate yet multidimensional, and holds up the stone in an uplifting way that really brings out the beauty of the center diamond. We named this ring Gefen because in Hebrew it means grape - and this design truly reminds us of grape vines studded with delicious grapes weaving themselves in and around a frame. This ring looks spectacular with both rough diamonds and cut stones such as sapphires or emeralds. We have sapphires on inventory that you could choose yourself for this piece, but emeralds we custom source. So, if you'd like an emerald, contact us directly.
We will get in touch with you after your purchase to confirm details. Please allow approximately 6 weeks to receive your ring. If you need it to be rushed or customized, please contact us directly at info@therawstone.com.

The Zorem ring is an artistic, flowing, and sculptural rough diamond engagement ring. The gold is crafted to appear as if it is melting from the top of the raw diamond, flowing down the shank of the ring. Like lava, or roots, the molten sides eventually converge to a smooth and comfortable band at the base of the finger. The stone is set in a sturdy and unique bezel setting.
Each ring is custom made to pair with the stone, so I will design around the stone you choose, ultimately creating your completely one-of-a-kind engagement ring that will be similar to the sample photos here. Before I create your ring, I will send you lifelike 3D renderings so that you can see what you will be receiving and provide any feedback.

Type of Stone: Diamond
Shape: Triangle/macle
Carats: 0.77
Measurements: 5.2 x 4.65 x 3.36mm
Color: Cognac
Description: This is an amazing raw diamond! It is a smooth and fall-themed color. It has varying levels of color concentration throughout the stone that gives a lot of intrigue. The raw diamond refracts light incredibly, and in three different directions according to its different angles. The center of the stone is clean and clear, and the surface appears perfectly smooth and gemmy, but on closer inspection, you will see natural etchings in the shape of trigons. It's an amazing piece.

Type of Stone: Diamond
Shape: Dodecahedron
Carats: 0.90
Measurements: 7.32 x 4.95 x 2.97mm
Color: Champagne
Description: A bright, regal champagne colored dodecahedral raw diamond. This diamond is unique in that it has a shape that gives it a "top" and a "bottom", almost like a pear but certainly more regal. This is a completely natural, uncut diamond, that came out of the earth just as you see it today. Its facets are natural crystalline structures formed by the pressure of the earth's crust on this piece of stone. It is completely clean and clear internally, and appears a bright, sparkly piece of sunshine.

Type of Stone: Diamond
Shape: Triangle
Carats: 1.35
Measurements: 7.15 x 6.32 x 3.17mm
Color: I-J, white and slightly tinted
Description: This glowing, and smooth triangular shaped diamond is a young version of a growing octahedral crystal. By young, we mean it has been growing in the millions of years, rather than the tens or hundreds of millions of years range. As you can see on the surface, there are fine lines, these represent the beginnings of the tower like grows that will pop up from the stone if it was still placed under the earth's mantle over the next millions of years. These lines are natural crystalline growths and follow the trend and shape of the original structure of the stone. It's a beautiful, glowing stone with a a clean interior. The center of the stone is white while the outsides have a bit of a more champagne hue - it gives the stone depth and uniqueness.

Type of Stone: Diamond
Shape: Rhombododecahedron
Carats: 0.76
Measurements: 6.55 x 6.72 x 2.25mm
Color: Golden yellow
Description: Lovely rhombododecahedral raw diamond, which really means it has a rounded flower shape. The center of this stone allows you to see directly into the heart of the raw diamond and it is clean and clear. There are three main lines in the stone that connect from the center outwards, and a more minor shape of a diamond that sits at the center of the stone and panels of facets lead down to the sides from there. There is a stronger concentration of yellow color on the outside of the stone which frames the stone in a really beautiful unique way.

The Te'anim is a three-stone raw diamond or sapphire engagement ring that is made to showcase three unique and ethical diamonds or gemstones stones side-by-side. The name Te'anim means "dates" in Hebrew, and we chose this name because the design reminds us of how dates grow on the tree beside one another on a branch, in various colors and shapes and sizes, and it's simply beautiful. Not to mention, dates are a symbol of life! The band is 2mm in thickness and is a comfort fit.

The Ezaria Ring is created from two hammered gold bands that join at the base of the ring. The bands separate until they reach the top, where they are held together by a rough diamond bridging one side to the other. "Ezaria" means helper in Hebrew, and the design serves as a reminder that we are helpers to one another in life.
This ring style works best with oblong or octahedral diamonds, which can extend gracefully from one side of the bands to the other. You have two options for the bands' finish—either a hammered surface or a smooth surface. Both options are showcased in the photos, so simply choose the style that resonates with you.
The stone you select will serve as the starting point for creating your Ezaria Ring, as the design follows the unique shape of every raw diamond. Your ring arrives as one unified piece—a wearable work of art.
Comfort is paramount; the ring is extremely lightweight with flat, delicate bands (each 2mm in width and 1.25mm in depth) for a comfortable fit.

The Ruah ring is a custom engagement ring with a raw diamond, the design inspired by nature. Within this ring we see the flow and the many aspects of nature such as earth, wind and sky. It is completely handmade from start to finish each time it is created. The six prongs contour the diamond perfectly to accentuate the natural curve of the stone. The band is textured with a hammered matte finish. The shape of the band is a comfort fit, so it wears extremely well and comfortably. The images for the ring are in platinum, but it is available in 18k gold as well. The ring is most suited as a rough diamond engagement ring, but would also be lovely with a sapphire.

The Shana ring is a rough diamond ring that is made to showcase its center stone with classic and unique grace. The band is a 2mm square shaped band with a slightly brushed surface. The center stone is held by four delicate handmade prongs that are uniquely shaped according to the stone set in the ring. We chose the name of this ring - which means 'year' in Hebrew - because we see this ring as representing the cyclic quality of life, and how we keep coming back to certain things or people or experiences along our journey. The ring is very comfortable and can be worn daily.

The Sal ring is a double pronged ring that encases the raw diamond in an ethereal basket-like architecture. The band has a naturally contoured hammering. The word Sal means "basket" in Hebrew, and we named this ring because it looks like this very seemingly mundane object that has so many significant and beautiful purposes. This ring design works lovely with larger or colored stones because it ever so slightly adds a small amount of ornateness to the basic diamond or sapphire. This ring works excellently with both rough diamonds and cut sapphires. We've done both, and as you can see from the photos, they all look stunning. This is a very comfortable ring and it also has the added benefit of holding the stone extremely securely because of the two prongs.
The stone you choose above will be our starting point for creating your Sal Ring, as the design of the ring follows the unique shape of every raw diamond. Your ring will arrive to you as one unified piece - stone and design together as your wearable piece of art.

The Ora ring is a sturdily and delicately bezel set rough diamond solitaire engagement ring. The bezel has an opening at the base so that light can enter the stone from both sides making this ring very bright and full of light. The name of this ring comes from Hebrew, Ora means "light of heaven" and we felt that this particular style brings a beautiful and otherworldly glow and light to one's hand. The bezel setting sits between the bands, so that the diamond does not sit on top of the band, but rather more flush with the finger. Each ring is handmade to fit the exact stone you choose. The half rounded band is approximately 2mm wide and 1.25mm thick, and sits lightly and comfortably on the finger so that it can be worn every day with ease.
The stone you choose above will be our starting point for creating your Ora Ring, as the design of the ring follows the unique shape of every raw diamond. Your ring will arrive to you as one unified piece - stone and design together.

The Midbar ring is a naturally contoured rough diamond solitaire engagement ring. It is made to elevate and showcase the raw diamond while giving it a refined and slightly earthy background. "Midbar" means desert in Hebrew - the contours on this ring remind us of the rolling wind-swept dunes in the desert. The beveled band is lightweight and wears extremely elegantly. The prongs are naturally and hand-shaped to grasp the center stone in a way fitting the uniqueness of the diamond. The band is approximately 2.25mm wide and 1.25mm thick, and sits lightly and comfortably on the finger so that it can be worn every day with ease.
