The principle of selecting crystal products in Crystal Amusement Park is not to be dyed or burnt twice. If there is a need to use non-natural or artificially dyed materials, we will clearly mark them in the product description. 2. We have adjusted the color of the picture to the color that looks closest to the actual product on our screen, but the color development of each computer screen will still differ slightly. The actual product and the picture may be slightly different, please accept. Subscript again. 【About the designer】 I am Xiaolang, settled south of the border, I have loved gems since I was a child, and I have been exploring colored gems for nearly 20 years. Obtained Class B license for gold and silver jewelry processing in 2010, In 2013, it passed the qualification of GEM-A FGA color gemologist of British Gemological Institute. I prefer a variety of colored gemstones, jadeite, and classic-style jewelry. The criteria for choosing gemstones is not only the color, but also the experience I have accumulated in the market for a long time to observe / judge the authenticity of gemstones. We don’t sell dyes and optimized gems that are not recognized in the market, In fact, no matter what kind of gems, there are very high-end and very low-quality products. Each level has its corresponding market block. It is impossible to take all the money with one amount. Through this reason, we have saved part of the management expenses and lowered the selling price, but It is not that the quality of the gems is not good enough, so some products in the store will be marked with the reference price of the physical channel for your reference.
