Ruby
is one of the highest valued colored gemstones, in fact, large rubies can fetch higher prices than equivalently sized diamonds. Ruby has been prized for centuries because of its excellent Mohs scale hardness of 9, along with its treasured rich red hue and vitreous luster.
A ruby is a pink to blood-red colored
Gemstone
,
a variety of the mineral Corundum (aluminum oxide). The red color is caused mainly by the presence of the element
Chromium
. Its name comes from
ruber
, which is Latin for red. Other varieties of gem-quality corundum are called
Sapphires
.
The ruby is considered one of the four Precious Stones, together with
Sapphires
,
Emeralds
and
Diamonds
.
Prices of
Rubies
are primarily determined by color. The brightest and most valuable "red" called blood-red, commands a large premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like
rutile
inclusions may indicate that the stone has been treated. Cut and
carat
(weight) are also an important factor in determining the price.
Ruby is exposed to
heat treatment
in order to enhance the colour.
This is considered to be a stable and permanent enhancement. Intact rutile inclusions (also known as "silk") provide proof that a ruby gemstone has not been heat treated. Ruby is also irradiated and treated with diffusion to enhance the colour. Other enhancements include
fracture filling
with lead glass, which is conducted to render heavily included gemstones fit for jewellery use. Occasionally, ruby is oiled or dyed. Despite all of the treatments that ruby can be subjected to, natural ruby gemstones are available and all reputable gemstone sellers declare any treatments or enhancements.
