8/18/2023 0 Comments Different shapes of diamondsThe general overall shape of a diamond – with a pyramid at one end and a wider “top” at the other – allows them to be set relatively easily into jewelry. These beautiful gemstones are not shaped into simple octahedrons or rhomboid shapes anymore – instead, they are carefully given a great number of different faces to create the perfect diamonds that we know and love. Why Are Diamonds Shaped The Way That They Are?Ĭutting diamonds is an incredibly complex, expertly skilled, and highly nuanced art form. If you’re shopping for cut diamonds, however, then the idea of shape gets a whole lot more complicated. Quartz crystals, for example, naturally develop a triangular pyramid projection at the end, which gives them a very diamond-like appearance and adds to the association between the shape and the stone. In their rough form, diamonds are vaguely octahedron-like in shape as well, and many crystals actually form with a similar geometric projection due to their internal structure and the way that the molecules align. This diamond shape is associated with the suit “diamonds” in playing cards, which is represented by the quintessential rhombus. It was known as the “Point Cut”, and slowly evolved through the years to the more complicated cuts that are commonly used in the modern era. Interestingly, the shape that we associate with diamonds now was one of the traditional cuts that were used many years ago, when the process of diamond cutting began in the 6th century AD. There are a few reasons why this name has been attributed to shapes like rhomboids and octahedrons. Why Do We Call It A Diamond Shape?Īlthough it does bear some resemblance to the projection on a three-dimensional diamond (the pointed end), the “diamond” shape is quite unlike the actual diamonds that you see today. When you actually think about it, though, this is not the shape of any real-world diamond that you will ever have seen.Įven the simplest of cut diamonds will be far more complicated and have a much higher number of faces than an octahedron. It has 4 triangular faces on one side of the shape, and another four triangular faces on the other side. You could almost think of it as two square-based pyramids attached at the base.

(All You Need To Know) With that being said, this shape is still one of the most famous and well-known quadrilaterals in the world, but what about the shape of a 3D diamond? How does that differ? A triangle from any direction is a triangle, and a rhombus from any direction is a rhombus. Shapes don’t have different names based simply on the direction from which you look at them. With one of its flat edges as a baseline, it is quite obviously a rhomboid, which has an appearance similar to that of a square that has been pushed to one side. If you rotate a “diamond”, you will see exactly what this means. Sometimes, this shape is also referred to as a “lozenge”, which can be a synonym for a rhombus, but generally refers to one that is slightly thin – with two acute angles and two obtuse angles. The only thing that separates it from being a square is the fact that the internal angles are not 90 degrees. It has four sides and two sets of parallel lines, and all of its sides are equal in length. The 2D diamond shape is technically a rhombus. There is no geometric shape known as a “diamond”, and what many people consider to be one is a different shape entirely.
