Shape
3 to fancies
Diamond prices are not only affected by the shape type (i.e.
pear, marquise, round etc.), they are also affected by the
attractiveness of the chosen shape. For example, an unsymmetrical
or a long and skinny marquise diamond cannot command the same
price as a well-shaped marquise.
The following diagrams show desirable shape outlines of five
basic shapes. A knowledge of the ideal round shape is assumed.
Let's
look at some diamonds with shape outlines that do not conform
to industry ,standards.
Note how wide the pear shape in figure 3.22 is. There is nothing
intrinsically wrong with this stone. In fact, it could flatter
a long, slen¬der hand. The jewelry industry, however,
places a greater value onpear with a more traditional shape.
Note how long and skinny the diamond in figure 3.23 is. Even
though it is priced less than a more traditional pear-shape
stone, it could be very flattering on someone with a broad
hand.
Note
how the diamond in figure 3.24 looks more like a shield than
a pear-shape. Some people prefer this shape, so this is best
for them. But normally, stones having an¬other shape than
intended should cost a little less.
If
you cut the diamond in figure 3.25 in half, the shape of the
two parts would not be equal. Even though many people like
free forms, symmetrical stones usually are more valued.
If you are buying a diamond for your own personal pleasure,
its shape doesn't matter, as long as you like it. However,
if you are buying your diamond mainly as an investment, you
would be wise to select a shape conforming to industry ideals.
Such shapes are often sold at premium prices and might be
hard to find.
You
may be wondering why all diamonds are not cut to industry
standards since they would be worth more. It's because too
much of the original diamond rough would be lost if it were
always cut away to form standard diamond shapes.
So
if the diamond rough is elon¬gated, one can expect the
cutter to fashion an elongated diamond. Buyers have different
tastes, too, and many of them prefer non-traditional shapes,
particularly, if they can buy them at a lower price per carat.
