The Different Sapphire Cuts
Oval shapes with triangular and kite-shaped
facets on the gem crown (upper part) and parallel rectangular facets on the gem pavilion
(lower portion) are quite frequent for corundum of all colors. The shape and size of the
finished stone are determined by the shape and size of a brilliant sapphire.
A
hexagonal barrel or spindle-shaped pyramid is the most frequent crystalline form of
unpolished sapphire. As a result, finished sapphires are frequently deep. Gem cutters work
on different factors such as color zoning, pleochroism, and a stone's lightness or darkness
to achieve the best overall color, maintain the ideal proportions, and retain as much weight
as possible.
The
most popular sapphire cuts are oval, round, and cushion. These are often used for many
varieties of jewelry such as rings, pendants, and earrings.
THE QUESTION
What You Should Take Into
Consideration When Cutting A Sapphire?
Sapphire is known for its color zoning,
which is the zoning of different colors in a stone. Blue sapphire frequently has angular
blue spots and a softer blue. To accommodate color zoning in some sapphires, cutters direct
the concentrated color to a spot in the cut stone that provides the best visible color. The
hue of Sri Lankan sapphires is frequently concentrated at the crystal's surface. If a cutter
can position the breech in the concentrated color area, the stone will appear fully blue
when turned face-up.
Pleochroism is the appearance of a distinct color in
multiple crystal directions. Blue sapphires frequently have a color of blue-blue-purple and
blue-purple. When setting the stone, it is recommended to orient the cut such that the
violet blue color is visible.

With over ten years of marketing
experience, I finally decided to settle down in Bangkok to work in an area that I have
always been interested in: the gemstones industry. I'm still learning how the market works
on a daily basis, and I enjoy sharing my experience with those who are interested in
learning more about gems in general.
