Product｜Colorful Blue Two-color Sapphire Quality｜<<Traditional Heating>> Two-color sapphire, a specialty of Australia. Although all sapphires have a certain degree of two-color, the two-color of Australia is the most obvious in comparison. Traditionally, sapphires are used for engagement, symbolizing the loyalty of marriage and love. If the wife is unfaithful to love, the deep blue color of the sapphire will gradually fade. Of course, first of all, sapphires are very expensive now, and not everyone can afford it. Secondly, in recent years, there has been a trend of using "two-color sapphires" to replace traditional sapphires for engagement. In addition to the more acceptable price, the two-color represents the combination of two different personalities (colors) or even different races. The meaning is clear, and the color is much more lively than traditional sapphires. Designers can be less old-fashioned in production, and it is widely accepted by young people. Although the price is usually about half cheaper than that of blue sapphires, compared with other types of gems, such as tourmaline, aquamarine, etc., the price of sapphires is still far higher than other gems regardless of color. Sapphire is still one of the best value-preserving items, unaffected by inflation, war, stock market crashes, etc. Sapphire is a crystal of aluminum oxide of the corundum type. It is extremely hard, with a Mohs hardness of 9, and only diamonds in nature are higher than it.
