Why is There a Great Variation In Ruby Prices?

There is a great variation in ruby prices that are very different depending on various factors like color, clarity, cut, carat weight, origin, and treatments that have been done to the stone. The priciest rubies possess the bright, pure red color, referred to as pigeon blood, are very clear, and are found in reputable sources of such gems as Myanmar. Price differentials between similar-looking rubies are further increased by market demand, scarcity of large or untreated stones, and changes in supply.
