Ruby has a mining history of thousands of years and is beautiful. It is one of the most popular jewelry investment collections, and the quality is the key to determine the value of ruby investment collection. The quality of ruby is mainly judged by color, clarity, cutting, weight and so on. The color is preferably pigeon blood red, pure and rich; Ruby is born with many cracks and inclusions, and the particles are fine, so the purity does not affect the beauty and durability of ruby. The larger the carat number, the harder it is. In terms of cutting, it is influenced by the size ratio of the original stone, the uniformity of color, the distribution of internal inclusions and other factors, as long as it can best express the color and fire color of ruby.
In addition to quality, origin and optimization treatment will also greatly affect the price of rubies, especially high-quality rubies. Many countries in the world produce rubies, the most famous of which is Myanmar, which has two ruby producing areas, Gumu and Su Meng. Mozambique is the most important source of ruby supply in the market at this stage, with excellent quality. In addition, rubies are also produced in Thailand, Viet Nam, Kenya and other places, and rubies are also produced in Yunnan, China.
Natural rubies with good quality can be said to be very rare and difficult to meet the needs of consumers, so optimization treatment has appeared. The most common optimization method of ruby is "firing". Ruby that only undergoes simple physical heating has been optimized, which has been recognized by the industry and consumers, and can be purchased as daily wear with high cost performance. If other substances are added in the heating process and remain after heating, it is treatment. This kind of ruby is not recommended to buy. The investment collection of rubies pays great attention to the rarity of rubies, and it is best to choose natural high-quality rubies with high rarity for investment collection.
