Rare Cut Diamonds: Discovering Uncommon Beauty

Diamonds are considered one of the most desired gemstones in the world, and their beauty is derived from their cuts, which determine their sparkle and brilliance. The cuts of diamonds are one of the most integral parts of diamond gemology and are influenced by factors such as symmetry, proportion and polish. Different cuts of diamonds, such as the cushion and princess cut, have become household names. However there are other cuts of diamonds that are just as beautiful, if not more rare and unique. In this article, we will explore some of the rare cut diamonds and discover their uncommon beauty.


At A.A. Rachminov, we pride ourselves on our exclusive selection of rare cut diamonds, which come in a variety of shape, size, and color, ensuring you find the perfect one to suit your needs.  From emerald to asscher cuts, each of our rare cut diamonds is handpicked and inspected for its unique beauty.


What Determines Diamond Cut Quality:

The cut of a diamond determines the diamond's overall beauty and quality, and it is an important factor when determining the best diamond quality. A well-cut diamond will reflect and refract light, creating exceptional sparkle, while a poorly cut diamond will appear lifeless, even if it has a high carat weight. Diamond cutters work diligently to create the perfect cut that maximizes a diamond's brilliance and fire. Here are the key factors that determine diamond cut quality:


  • Symmetry: The symmetry of a diamond refers to how perfectly aligned its facets are. If a diamond has poor symmetry, the light that enters it will not be reflected and refracted correctly, and it will not sparkle as brilliantly.
  • Proportions: A diamond's proportions refer to how deep or shallow it is. If a diamond's proportions are incorrect, it will reflect light in the wrong way, resulting in a dull appearance.
  • Polish: The polish of a diamond refers to the smoothness of the diamond's surface, which affects how much light enters the diamond.

List of Rare Cut Diamonds:

While there are many cuts of diamonds available in the market, there are some rare cut diamonds that are not commonly seen. Here are some of the cut diamonds that are rare but absolutely stunning:


  • Pear Cut Diamond: The pear cut diamond, also known as the teardrop cut due to its shape, is a hybrid of the marquise and round cut diamond. It has an elongated shape with one end that is pointed, and the other end that is rounded.
  • Radiant Cut Diamond: Radiant cuts are rare; only less than 2% of diamonds cut today are Radiant. The radiant cut diamond is a rectangular-shaped diamond with trimmed corners. This cut diamond is specially designed to display the maximum brightness and fire of a diamond.
  • Emerald Cut Diamond: Only 3% of the world's diamonds are emerald cut, which means they are rare and harder to find. The emerald cut diamond, originally designed for the emerald gemstone, has a rectangular shape with chamfered corners. 
  • Asscher Cut Diamond: Diamond cutters only cut about 2% of diamonds into Asschers. The asscher cut diamond is square-shaped with a large number of facets, creating a mesmerizing pattern when viewed in the light.
  • Heart Cut Diamond: The heart cut diamond is a romantic and rare cut diamond, which requires great expertise to create. It has a pear-shaped outline with a cleft at the top.
  • Marquise Cut Diamond: The marquise cut diamond is distinguished by its boat-like shape, which is elongated with pointed ends. Its lengthy shape can create the illusion of a larger size, and the sharp ends can give the diamond an exquisite and dramatic flair. Cut to enhance brilliance, the marquise cut diamond is a stunning and unique choice that is not commonly seen.
