Although the hardness of rubies is relatively high, they are brittle. Large-carat rubies are not common, and eight to nine percent of rubies are burned internationally, това е, very good color and clarity are obtained by physical heating. Although such a gemstone has not changed its natural characteristics, it is not purely natural after all. As a result, the price per carat of gems of the same grade without burning is nearly doubled. Следователно, rubies should be stored as far as possible without burning, the weight is best to be greater than 2 Карати, the brighter the color, толкова по -добре, the clearer the better, the cut should pay attention to proportion.
ruby value
The general industry believes that rubies must be at least 3 carats or more to have a certain investment value. In addition to color and weight, the origin is also very important to the price of rubies. The highest price on the market is Burmese rubies.
The scarcity of ore resources is the main reason for the increase in ruby prices. With the flood of liquidity causing global inflation, some buyers buy rubies in large quantities to achieve the purpose of asset preservation and appreciation. Various factors continue to push up ruby prices. , The financial attributes of rubies now exceed the collection attributes.
В днешно време, only natural rubies have investment value and cannot be processed manually, and the rubies invested should have the certificate of an international authoritative appraisal agency. When some businesses heat rubies to a certain temperature, they can improve the color and transparency of rubies, so pay attention to them when storing them.
