ratnanayaka meaning "leader of precious stones." It is the birthstone for
those born in the month of July.

expensive. Therefore, artificially red colored rubies are created by man
made methods that are relatively quite cheap. Sometimes, few clever buyers
sell these cheap stones at the price of the original gemstone. In order to
avoid all future surprises buyers should ensure the credibility of the
dealers. The seller must inform the buyers about the gemstone treatments and
origin clearly. He/she should also give the certificate of authenticity
along with the gem at the time of purchase to the buyer. This article is
written with the intension to provide the gemstone lovers with all possible
facts and information about the valuable red colored precious gem. This
content would acquaint the buyers with the essential know-how about this
remarkable gemstone.
Colour - It is an extremely important characteristic. Being the
member of mineral corundum (aluminum oxide) family, this exquisite gemstone
owes its pure red colour to chromium element present in the chemical
composition. Brightness and intensity of red colour increases with the
increase of chromium. True and genuine gem possess intense saturated pure
red colour with no tinge of either brown or blue. The glow of red colour is
similar to that of burning coal. This amazing gemstone holds its beautiful
colour in all light variations.
It is found in all shades of red however deep red colour is the preferred
choice. The distribution of colour is mostly uneven that might be stripes or
spots, supposed as pigeon's blood, clear red with a trace of blue. The basic
red colour mostly also comprises overtones of other colours. Colour
variations are different in each single stone that is no two stones have
similar overtones. Few commonly seen overtones are red with yellowish to
orange tones or blue to purple tones. All these colour variations
complements the main colour and gives amiable look to the gemstone.
Clarity - Second important characteristic is the transparency. It
is the known fact that inclusions are always unwanted but with this gemstone
it is different!! Certainly it is undesirable to have inclusions however
these act as the certificate for the genuineness of the gem. All original
rubies would consist of flaws. Chromium is liable for imperfections within
the structure of the gemstone. The colour increases in direct proportion
with the amount of chromium in the chemical composition and so is the
clarity. The biggest difference lies; colour is positive trait while clarity
becomes negative. Chromium results in large number of fractures and
infinitesimal indiscretion inside the crystals. This is the reason why this
marvelous gemstone always consists lots of defects. Ruby without any
inclusion is miracle of the nature and thus it is priced as high as sky.
Cut - Beauty of the stone lies in the hands of the cutter. The
final look is dependent on the cut being given to the gem. With the perfect
cut, the stone could appear bigger in size in spite of being less in weight.
It is often offered mixed cut, that is by and large oval, but could be round
or any other shape like square, rectangle etc. Ruby beads or cabochons are
also extensively seen in the jewelry market.
Carat Weight - It is found mostly in small sizes and less carat
weight. Gemstones beyond 3 carat in weight are exceptionally rare and scarce
in nature. This captivating gem is priced very high per carat and when it is
more than 3 ctw then the price per carat weight gets doubled making it
enormously pricey.

after and treated as luxury stones. Then comes Thailand and Sri Lanka
followed by other parts of the world. Pure intense red colour, minimum flaws
and high carat weight are the pinnacle points in terms of price determinant.
Financial value of the gem increases with the increase in these points.
Original gems possessing all the summit points at the auctions outdo every
other thing.
Few high quality gemstones exhibit unique phenomena of six-point star
pattern, called asterism. It is caused due to fine rutilum needles present
in structure along the crystal facets. When light is reflected from these
needles the stones displays the star pattern. Such gems are over and over
again fashioned into even cabochon cuts to best flaunt the phenomena.
Further, when seen under a complimentary light source the star gives the
impression of moving from one corner to the other corner of the stone with
the change in the lighting angle. These gems are called as 'Star Rubies'. It
is rare in nature and very expensive. These gems must show varied rays and
the star should be visible in the center of the stone. Price is determined

negligible clarity are found in Karnataka and Orissa state of India.
Enhancements - Enhancement is common for this divine gemstone. It is treated
to enhance the colour and improve the clarity. Man-made dyes are used to
augment the colour while surface fractures are hidden through coatings. An
ordinary coating does not last for long. Thermal enhancement is considered
constant and everlasting. Under this process, the chemical like sodium
tetraborate powder is melted under very high temperature and coated on the
surface of the stone. The liquid chemical enters the fractures and covers it
up. After sometime, the chemical solidifies as an amorphous solid and hides
all the flaws. The international gem and jeweler trade acknowledges this
treatment.
