Shapes of Uncut - Rough Diamonds

When we hear of Diamonds, the first picture our mind creates is that of finely crafted, glittering

piece of jewelry adorned by your favorite actress in a commercial or of the movies wherein the

entire cast fights to track down a priceless diamond. A whole bunch of movies are directed with

the same theme which highlights the preciousness, uniqueness and rarity of this stone and

makes diamond the king of jewels. The polished, faceted diamond indeed holds great sparkle

but have you ever wondered of the stone in its natural form? The charm of this priceless stone

in its raw form is still a showstopper devoid of those perfect cuts and polishes. With the

growing awareness about the natural beauty of this timeless crystal, uncut diamonds are the

new favorites in the industry. The rough or raw diamonds, as they are commonly referred as,

are naturally formed in different shapes and sizes. They hold a unique and natural charm which

is hard to resist. Raw diamonds are usually found in common shapes like octahedrons while a

few other shapes like Tetrahexahedrons are a rare occurrence.

Technically, crystals get their shapes based on the internal structure and arrangement of atoms

 inside them. Diamond falls under the cubic crystal system which has the highest symmetry

among the crystal systems. The growth processes deep within earth bring about changes in this

structure and eventually lead to unique formations which are ideal candidates for exclusive

adornments.

To start with, Octahedron is the most commonly found natural shape of rough diamonds. It

resembles two pyramids attached at the bottom the two points facing away from each other.

The Octahedron is generally sawed in the center to form two polished diamonds. Diamonds

derived their name from the octahedron structure which when polished and cut in right angles

results in the desired rhombic shape. Rough diamonds are usually found in this shape though

the edges might not be sharp enough as that of a finished one. Well, that is where the natural

beauty outshines the crafted counterpart.

Dodecahedrons are a slightly tweaked version of octahedrons which consist of 12 equally sized

rhombic faces. They may appear rounded due to the convex nature of the faces. In a few

Dodecahedrons, a prominent ridge doubles the number of crystal faces from twelve

 

to twenty-four. The latter are then termed as tetrahexahedrons which are basically rounded

 Dodecahedrons. In some cases, the shape of a diamond may resemble more than one defined

shapes and hence becomes a unique candidate for your treasured jewelry.

Cubic diamonds on the other hand are usually opaque but are usually found in different bright

colors like yellow, red, green, orange and brown. The shape of cubic diamonds resembles tiny

dice and is quite distinct in appearance. It is quite rare to find a cubic diamond and because of

their internal structure, cubic are not an ideal candidate for cut and polished. Rather they help in

having unique jewelry designed with the stone in its natural form.

Trigons or triangular shaped diamonds are the ones which look like a growth pattern

resembling a series of triangles within triangles. These are one of the rare occurrences of rough

diamonds which are formed because of a growth process deep within earth’s mantle.

Twinned crystals such as ‘Macle’ are the flat triangular crystals which is a result of crystal

distortion. It may be a challenge for a designer to shape this crystal since the internal formation

of atoms is tricky.

The reason for which a typical shape of a raw diamond makes it an invalid candidate for

polished jewelry is indeed a blessing in disguise for someone looking for a unique

embellishment. Go ahead with creating a regret-free ‘one of a kind’ experience with raw

diamonds and bring home an eternal beauty.
