I think this bracelet should be a real aquamarine bracelet. Aquamarine is a beryl in mineralogy. It is mostly produced in pegmatite, and its output is not low. Of course, there are very few that can reach the gem level. Your bracelet has the typical glass luster of aquamarine (glass luster, not glass, glass luster is one of various gem luster, others have diamond luster, sub-diamond luster, grease luster and so on. ), and the stripes on the bracelet also conform to the common cylindrical longitudinal characteristics of aquamarine, so it should be an aquamarine bracelet, and there is no mistake. But there are many optimization treatments for aquamarine in the market, such as heat treatment. If you are very concerned about whether it is a pure natural unoptimized aquamarine bracelet, you can send it to a jewelry appraisal agency to help you get an appraisal certificate. In addition, now you can ask the seller to issue an identification certificate for the goods when buying jewelry in formal channels. It is best not to buy gemstone products without certificates, which is prone to problems. Of course, the certificate may be forged, but the problem of not having a certificate is even bigger. Authoritative gem appraisal institutions include: NGTC National Jewelry Quality Supervision and Inspection Center, China Geo University Inspection Center, etc. The formal gem and jade appraisal certificate should be stamped with steel seal and have CMA, CNAS, CAL and other recognition marks.

In addition, from my personal point of view, if your bracelet is not optimized, then the color is still quite good. The sky is blue, the blue degree is not bad, the transparency is not bad, and there is a little more cotton, but the price is quite acceptable and worth sending for identification.
