This is a set of a Brazilian beryllonite loose gemstone and an S925 (Sterling Silver 925) setting with a bail. According to Robert Simmons, the creator of Azeztulite, beryllonite has a higher vibration than phenacite and possesses a higher wave frequency. This beryllonite has high transparency, is clear and beautiful, and I believe it is a rare loose gemstone. A Japanese-German Gemological Laboratory sorting report for the loose gemstone is included. Please check the size in the images. Both the setting and the loose gemstone are new. Hallmark present (see image). Necklace chain is not included. There may be fine scratches unique to natural stones and fine scratches from the manufacturing process, so please refrain from purchasing if you are looking for the high quality of fine jewelry. Due to the extremely rare nature of this stone, returns are not accepted to prevent substitution. #NaturalStone #Rare #RareStone #HighVibration #PowerStone #Beryllonite
