The price of the ruby will start from Rs. 1000 per carat ($14) and can go up to Rs. 250000 per carat ($3568) and above depending upon all the factors. The price of the ruby (Manik) many depend upon 6 factors CUT, COLOUR, CLARITY, CARAT WEIGHT, ORIGIN & TREATMENT.
Cut- The cutting of the stone/gemstone not only enhances the beauty of the gemstone but also conceal the inclusions. A better faceted Ruby or Manik is priced more over a normal or odd shape ruby.
Color- The color of the ruby is caused by the traces of chromium. Color is the most significant factor affecting a ruby's value. Rubies are available in rich red to dark red and orangey red to purplish red. The most sought-after color by collectors worldwide is a deep red sometimes with a hint of purple, called pigeon's blood in the trade. Price of the ruby largely depends upon the color of the ruby.
Clarity- Inclusion free ruby is substantially hypothetical so the price varies with how visible the inclusions are. Inclusions can also impact a ruby's durability, especially is there is a surface - reaching fracture. Rutile needles, or silk, can sometimes add to a gem's look. The clearer the ruby or Manik, the higher the price.
Carat Weight- Original ruby above few carats is rare to find. The better the size of ruby higher the price. Price of ruby per carat will increase with size.
Origin/Source- The most popular ruby mines are in Myanmar (Burma) however rubies can also be found in Vietnam, Africa, Mozambique, Madagascar, Tajikistan & Afghanistan. Ruby from Bangkok or Thailand is considered economic as they are generally treated, not useful for astrological values.
Treatments- Heat treatment is often used to improve the color or clarity of a Ruby. Heat can also cause some fractures to "heal" in certain conditions. A cheaper quality material may have surface-reaching fractures filled with glass to reduce their clarity and make the gem more natural. These treated Rubies will never give astrological benefits to the wearer.
