The Magen ring is a rough diamond solitaire engagement ring that is set in a totally unique way. The diamond is placed in a custom-created criss-cross basket setting to securely hold it but also to showcase the absolutely uniqueness of the rough diamond and its nontraditional look. We chose the name Magen for this ring because in Hebrew it means "shield". The design looks like a diamond studded shield of shiny gold protecting its inner raw diamond. Along the criss-cross are small cut diamond melee and you can choose whether or not to include diamonds on the top half of the band.
The stone you choose above will be our starting point for creating your Magen 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.

This customizable rough diamond engagement ring with a multihued sapphire cluster is out of this world beautiful. It is a stunning engagement ring that has an otherworldly effect beyond its physical manifestation. The word Raziel is the name of a Hebrew angel who is the angel of magic, mystery and secrets. We named this ring after this angel because this ring has this mysterious, magical effect by playing with color, shape and light that extends beyond its physical beauty.

The ring models shown contain a rough diamond at their center with an ethereal cluster of three cut and polished sapphires at its side of various hues and shapes. The three sapphires are absolutely natural and are in a spectrum of shades, though you will have the option to choose any color and shape you would like. The cut and multicolored sapphires standing beside the naturally formed and colorless rough diamond contrast and complement one another simultaneously. It's such a beautiful metaphor for the perfect relationship built into the most breathtaking and ethical engagement ring.

A note about the source:
We sourced the sapphires as rough directly from our partner mine in Sri Lanka. It is an artisanal family-owned and operated mine that adheres to the highest labor and environmental standards in Sri Lanka. We sourced this rough diamond through a siteholder in Ramat Gan, Israel and therefore we are able to trace it directly to the mine in South Africa.

The Hila ring is a rough diamond halo ring with conflict-free melee surrounding the center rough diamond on a simple high polish band. The contrast between the two types of diamonds in this ring is both complementary and intriguing. This particular ring looks excellent with unique rough diamonds as the center stone because we love the contrast between the cut and rough diamonds. The smooth high-shine band is extremely lightweight and wears very comfortably and elegantly. The prongs are naturally hand-shaped to grasp the center stone in a way fitting the uniqueness of the diamond. The band is 2.5mm wide and sits gently and comfortably on the finger so that it can be worn every day with ease. Create your own ring by following the steps below. For reference, the sample ring for this photo is 14k white gold.

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.

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: 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.

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.
