Here’s Everything You Need to Know About the Triangle Cut Diamond

Triangle Cut Diamonds

​The diamond industry is growing rapidly, and new designs are frequently being introduced. This helps people gain access to more choices when buying engagement rings, pendants, earrings, and other jewelry items that are fitted with these precious gemstones.

A relatively popular term used in the modern day diamond industry is triangle cut, but when you take a closer look at brands offering diamonds, you will often notice that this particular shape is not mentioned in their collections.

Triangle cut, sometimes also referred to as the triangular cut, is a collective term. This term is not used to describe one specific diamond cut, but rather a number of different diamond cuts that all resemble the shape of a triangle. Let's take a closer look at the triangle cut and the various diamond shapes that fall into this category.

​An Overview Of The Triangle Cut

A triangle cut diamond is usually a term used to describe the shape of a Trilliant cut diamond. Other generic terms are also sometimes used to refer to these diamonds. A few examples include Trill cut, Trillion cut, and Triangular Brilliant cut. These stones offer a flexible variety of options when it comes to fitting them into jewelry pieces. They are often used in rings combined with a series of side stones. In addition to being a perfect placement in different ring settings, triangle cut diamonds also offer a great addition to necklaces and earrings. A solitaire pendant necklace would be a perfect example of how a triangle cut diamond can be used in a necklace.

​Triangular-shaped diamonds are known for a sharp brilliance and an exquisite level of fire. They can either feature a total of 31 or 50 facets. These shapes were initially introduced in 1962, making them a relatively new addition to the many diamond shapes and cuts that are out there. One particular factor that is seen as a big advantage to opting for one of these diamonds is the fact that they are able to hide inclusions better than many other diamond shapes​ currently available on the market. With this in mind, it means you can save a significant amount of money by opting for a lower clarity rating, yet the diamond will still look pleasant to the naked eye.

​When you consider buying a Trillion cut diamond or a triangle-shaped diamond, you should ideally look for a stone that has a length-to-width ratio of 1.00. This will provide a far superior overall appearance as compared to other length-to-width ratios since the diamond will be cut to a better proportion.

Similar to many all other diamonds, a triangle cut diamond will be graded based on the four C’s associated with the quality of a diamond. A gemologist will consider the clarity of the diamond and the color of the diamond while grading the stone. They will also weight the diamond to provide an accurate measurement of its carat weight. Its cut quality will be assessed, but not like a standard round brilliant cut. Instead of providing an overall cut quality, a grading report for a triangle diamond will instead include a detailed description of the table %, depth %, girdle, culet, and more.
