76Corundum, rubies and sapphires
Want to know about quality, properties and origins of beautiful precious gemstones red colored rubies and blue and yellow sapphires? This article is for you who are interested to have in depth knowledge of these colored gem stones.
Ruby belong to corundum family. Blue sapphire, yellow sapphire, pink sapphire and green sapphires also belong to the same corundum family. Chemically, all these stones are similar.
Properties of corundum: Properties of rubies and sapphires are similar to corundum. Corundum has hardness of nine in Moh's scale and specific gravity around four.These are the hardest gemstones but diamonds and one of the heaviest too. Corundum contains aluminum and oxygen. Natural corundum is opaque but some times it reacts with water in the mines and takes a crystalline form. This crystaline structure converts it into gemstones.
When corundum comes into contact with coloring agents likes of chromium, nickel etc (in a very small quantity) and reacts chemically inside the mines, it converts naturally into Ruby or Pink-blue-yellow or green Sapphires.

I would like to buy a blue sapphire stone flawless but not very expensive preferably of Kashmir can you suggest for a ring
Dear Yashdeep,
Thanks for your comment and query. I am not an astrologer but a gemstone dealer.
To the best of my knowledge ruby is worn in ring finger studded in gold. If one can not afford gold he should wear in copper instead of silver.
Thanks,
Jyoti Kothari

I want to buy a red coral for my wife. what is the price range?
Dear Shoukat,
Price of rubies varied in wide ranges. You can get it for $ 0.25 per carat and you can go up to $ ten thousand per carat for some nice Burmese piece.
It all depends upon color, clarity, carat weight, cut, origin, luster and many other factors.
You need to see the piece yourself and consult an expert and trust worthy Gemstone dealer.
Thanks for your comments.

Quality Origin Properties of Ruby Saphhire
Very creative
I love blue sapphires and like to buy some. Is Kashmir sapphire a best buy? Is it easy to afford?
Ruby is a very hard stone because of its crystaline structure. Normally it is not scratched but still one should be careful when wearing a precious stone.
Why ruby is so hard? Will it get scratch while wearing it?
Ok. I will edit my hub and add this description.
