The origin of a color gemstone will play the least role in price. However in some cases it will make it more valuable such as a Sapphire from Kashmir, as it is rare and has exceptional color. Tanzanite are found in one location making them high priced as well. Ruby and Emerald may also be considered more valuable depending their origin. In most cases origin will not matter.
Other color stone factors that affect price:
• Carat weight
• Treatment (is it treated or untreated)
