Pear shaped diamonds are often called teardrop diamonds and is technically, an evolved version of the popular and standard round brilliant cut. Another cut which closely resembles the pear shaped diamond would be the Marquise cut. They are almost similar in cut pattern. Marquise cut used to be one of the earliest diamond cut but it went out of style due to several reasons.
Both of these cuts have same small and fine facets. Small facets makes these cuts very efficient in hiding flaws and impurities which a diamond might inherently have. While round brilliant cut is the best when it comes to sparkle and brightness, pear shaped diamonds don't lag far behind, especially if the cut is performed on high quality round diamond.
Pear shaped diamonds have some unique features. They have single pointed end and this is the only existing and still used diamond cut to have this feature. Cropped corners and softened edges are more in circulation nowadays as pointed and sharp corners and edges tend to chip, dent and damage easily. Moreover, cutting sharp and pointed corners is difficult as well, keeping the balance intact. Sharp corners also lead to surface damage and symmetrical flaws. However, when this difficult cut is achieved perfectly, the result is an unimaginable beauty which no other shape can offer.
Pear shaped diamonds are mostly used for earrings, especially the Indian style 'jhumka' or the dangling earrings. It is also used for necklace pendants where the diamond is used as a dangling piece. The teardrop shaped pear cut diamond is also used for engagement rings, although that is not as widespread a practice as using the round brilliant cut is. However, if the engagement ring indeed is made using pear shaped loose diamonds, the wedding gift should also contain the same and together they would create a magical effect.
Another amazing and unique characteristic of pear shaped diamonds are that they display the bow tie effect, as it is commonly called. This refers to the dark spots, the point where two symmetrical triangles are meeting, much like in a bow tie, and is visible from the top of the diamond. This is visible to the naked eye and thus, you don't need any magnifying glass to witness this. However, the diamond certificate doesn't mention this so you better have a look for yourself. In fact, you should check the diamond from every angle before purchasing it.
