The phrase "fancy shape" is oftentimes used to direct to a diamond that is not a round fantastic cut. The factors involved in judging the divide of a fancy shape diamond differ according to the diamond shape lifetime assessed.

The distinct fancy diamond shapes include: oval, pear, marquise (boat shaped) square and rectangular. Cuts for fancy shapes involve emerald, princess and Asscher cuts.

Some cuts, such as the princess cut, hog diverse facets complementary to the brilliant cut, whereas others, such as the emerald cut, are step-cut and hold far fewer facets.

There are many, abounding factors involved in assessing fancy cuts, and all the more has been written on the subject, so for the purposes of this article I shall concentrate on a infrequent of the most distinct pitfalls to be avoided when purchasing a fancy shape diamond.

The Bow Tie Effect: This is probably the most public and exposed disagreement with oval, marquise and emerald reduce diamonds. The "bow tie" is a drab world in the centre of the diamond, occurring when the pavilion is decrease besides far or is improperly proportioned. A pronounced bow tie can be express distracting and can seriously prevail the flare and overall petition of a diamond.

The Window Effect: A window is a clear, washed-out earth in the middle of the diamond, caused by a pavilion that is very shallow. In utmost cases, remarkably in emerald section diamonds, it is imaginable to peruse print ended the table of the diamond when it is placed face down on a newspaper.

The Fisheye Effect: A fisheye can eventuate in poorly intersect round brilliant diamonds as fit as in various fancy shapes. It normally occurs in diamonds where the table is extremely large, and the pavilion is also shallow. It is caused by the echoing of the diamond's girdle (outer edge) back terminated the table. A diamond with a pronounced fisheye testament seriously distress flash and its cost will be even diminished.

These undesirable features in diamonds usually befall when the cutter has tried to maximise karat weight from the rugged crystal. In his crack to author a preferable diamond from the available material, he has sacrificed grace in favor of a higher quality stone. In my opinion, this is a false economy, considering a diamond that lacks bright is not the configuration of attractiveness that a diamond should be. I would far prefer to keep a graceful half-carat diamond than an gross one-carat diamond for the alike money. As I frequently do in my articles: Caveat Emptor, which for non-Latin scholars wealth Buyer Beware!
