Colored gemstones are not just accessories for women's looks and temperament. Men can also enjoy the gem collection and gem investment, and taste the colored elves that collect the essence of the world.
How to buy colored stones? A few days ago, Tang Huimin, a gemologist from Taiwan, shared his gemstone shopping skills with Jiujiu Street in Dazhao Square, Hohhot City. According to Tang Huimin, there are many kinds of colored gemstones, including rubies (pictured), sapphires, emeralds, tourmalines, saffron, grapevines, etc. The price of colored gemstones depends on its color, flare, inclusions and impurity cracks, transparency, cut, polishing, rarity of mineral resources, political factors of origin, artificial speculation and other factors. However, there are five general rules for purchasing colored stones for reference.
Look at color
The darker the color, the more saturated, the more uniform, the brighter the better. Within the same family, it is usually cheaper to use black and white transparent treasures.
Look at the cut
The stronger the fire, the better. A fascinating gem must be the most appropriate cut to shine.
Look at inclusions and cracks
The cleaner the more expensive. However, it should be noted that the completely transparent flawless gemstone (ruby, emerald), the more suspected the synthesis.
Look at the weight
The bigger the more rare. In the case of rubies, it is better to buy a 5-carat ruby ​​and not to buy five 1-carat rubies. Because the bigger the gems, the more rare they are, the more expensive they are.
Look at the place of origin
Some gemstones are produced by the store, and sometimes the gem wholesaler may be wrong. The retailer is also wrong. See more, ask more, compare more, to see the clues. Tang Huimin specially reminded that if you purchase precious stones, you need to provide international certificates, such as GRS, GIA, or national inspection and quality inspection certificates.
