How to choose a good quality ruby at affordable prices? Cost depends on a combination of all factors considered in the previous parts of this article. The most important factors affected price are the following: color, information about enhancement, weight value. The brighter and more saturated red a corundum is, the higher a price is. Also with weight increase a rarity rises, because small rubies are more common, therefore, the cost also increases. Untreated rubies are much more expensive than treated gemstones, and they usually have a certificate that confirms their natural origin. An unheated sample can cost 2-3 times more than a heated stone with similar characteristics of weight and quality. Gem-quality ruby without a certificate may cost less than with it, but there will be a risk linked with natural origin and fact of enhancement.

In international practice it is accepted that the cost of precious stones is given in US dollars per 1 carat. There are several organizations that produce price guidelines for stones in the form of tables depending on mass and quality. Before to analyze specific market offers, find out the approximate price level of certain positions in such publications. How much a carat of ruby worth you can learn about, for example, from the magazine Gem Guide. According to data from this magazine for May / June 2015, the cost of rubies per carat in US dollars (USD), depending on quality, origin and treatment, on the example of faceted stones 3-4 carats, will be approximately the following (in order: heated without reference to the deposit / unheated, from Mozambique / unheated from Burma /):

  • Low commercial quality - 75-915 / 585-2080 / 2200-3500.
  • Good quality - 1455-4375 / 2730-7800 / 5250-12880.
  • Very good quality - 5625-8750 / 9750-17550 / 16800-37800.
  • Excellent quality - 11250-23125 / 19500-32500 / 40600-70000.
  • With increase of weight, cost of ruby per carat also increases. For example, in this magazine for samples of excellent quality weighing 4-5 carats, the cost is already given in the ranges 15600-20550 / 28600-45500 / 63000-91000.

How much does a precious ruby of certain quality characteristics cost can also be understood based on various market offers. Comparing prices is necessary for very similar rubies of approximately the same weight. Keep in mind that color is often distorted in photos. Therefore, the decision to purchase of an expensive gemstone is better to take, viewing a stone alive, based on the practical recommendations discussed above.
