ruby the world has idealised. So when you step into the market, there is sizable ruby with great looks being
offered at an affordable price.
When the former is the truth, how is this ruby being made available and at such costs? Read more to know
about this gorgeous gemstone and the market truths…
Ruby jyotish gemstone
One of the most precious and rare gemstone is ruby. Natural ruby of good quality is known to outdo colorless
diamonds in price. There have been auctions by the two bigwig Christies and Sotheby's where rubies have
fetched incredibly handsome amounts! Natural ruby is mineral corundum (same as sapphire) but is much
rarer than sapphire. It is a gem that has been coveted by royalty and noblemen; the rich and the powerful for
centuries, who have been enamoured by this gem that is symbolic of blood, courage, passion and love.

3. Ruby Gemstone Mineral
Natural ruby is mineral corundum (aluminium oxide - Al2O3) coloured red by presence of trace element
chromium. An important physical characteristic of ruby is its inner glow - ruby actually fluoresces
Synthetic ruby is the same chemical composition but is manufactured in the lab using the flame fusion
process, unlike the natural ruby which is formed in nature over millions of years. Synthetic ruby is available in
the markets for few dollars per carat, while natural ruby is rare and precious.

Sources of Ruby gemstone
Natural ruby traditionally has meant “Burmese ruby” or “Burma ruby” - the one coming from the Mogok
valley – the one with theimperial pigeon blood color. However, supplies dried up as far back in time as 1962,
when the Mogok mines were completely dug out. The rule of the military junta did not help either. While the
price of ruby soared, the lovely deep red of Mogok could not be found anywhere no matter where
prospecting and mining was done for rubies.
Around the year 2000, new deposits were found near Mong Hsu in Burma but the Mong Hsu rubies had a
blue/ purplish hue to them. This was corrected and appearance was enhanced using heat treatment. For an
individual buying a Burmese Mong Hsu ruby, it should be assumed that it is heat treated. Any natural,

higher price.

In search for ruby after the end of Mogok story, Thai, Vietnamese and Cambodian rubies were discovered
and mined. Thai rubies were nice but had a deep red color due to high iron content making it look almost like
garnets. Most of these rubies were heat treated for visual enhancement. Rubies from this belt display blue or
purplish hue quite strongly and therefore are invariably heat treated.

Ruby deposits were discovered in Mozambique and Tanzania belt that did yield fairly good ruby. There were
also discovery of ruby gem deposits at Vatomandry and Andilamena in Madagascar. Although the color and
the crystal of the Madagascar ruby is generally not very good, exceptional gem material does come through
sometimes. The Tanzania ruby, coming from the Winza mines is said to be pretty close to its Burmese
counterpart in appearance.

Then there are the Tajikistan rubies that come from the mountainous Murghab in Gorno Badakshan area.
These rubies are produced in marble deposits and are of red and pinkish red color.
Ruby gemstone deposits have been found in India, quite significantly in Orissa but are low quality with poor
clarity and more of a marbled look. Star rubies or Rubies displaying the special optical phenomenon of
asterism from India are however well known. This is because star rubies are cabochon cut and clarity does
not matter. In fact, low clarity gems are often shaped as cabochons.

Treatments in Ruby Gemstone
the most well known treatment for rubies is heat treatment where rubies are heated to around 1700 degree
centigrade (a little below their melting point), at which temperature the inner silk melts and the gem is
enhanced with better clarity and color. Heat treatment done to various specimens of rubies of varying
qualities will yield different result.

Traditionally, the other treatment of rubies has been of fracture filling in the rubies with lead glass, as it has
its refractive index closest to corundum. The resulting ruby is much clearer and beautiful.

However, setting such pieces of glass filled ruby in jewelry pieces is difficult as torch heating while setting
may melt the lead glass which has a much lesser melting point leaving the ruby damaged and ugly looking.
There is a newer variety of ruby doing rounds in the market now being sold as “composite ruby”. Beware of
the fancy name. It is just small pieces of corundum bonded together with lead glass to form a ruby. And this
ruby corrodes easily when it comes in contact with house hold chemicals as well as lemon juice! One
wouldn’t expect this after a hefty price paid!

At any retail entity, proper disclosure of any treatment done to the gemstone is an absolute must.
The World Jewellery Confederation known as CIBJO does not recognize composite stones as genuine
gemstones. CIBJO defines composite stones as: "artificial products composed of two or more, previously
separate, parts or layers assembled by bonding or other artificial methods."
Do ask for certification, origin and receipts while purchasing your precious ruby- whether you are buying ruby
necklace, ruby earrings, ruby pendant, or even loose ruby stone! You would not want to give a ruby
engagement ring to your beloved and later discover that the price you paid was for a fake! Gemstone
therapy works only with Natural, Unheated beautiful Rubies that excel on the 4C's of cut, color, clarity and
carat weight.
