Please comment before purchasing due to the popularity of this item. This is a natural aquamarine necklace. Stone size: Approximately 21x16x12mm Weight: 15.5g Aquamarine, as its name suggests, is a gemstone the color of the sea. It is said that if you throw it into the sea, it will instantly dissolve, and because of this, old European sailors cherished this stone as a talisman imbued with the power of the sea. The deep marine blue stones mined from the Santa Maria mine in Brazil are considered to be of the highest quality, but this mine is now depleted. However, recently, stones of similar quality have been mined in other mines, and these deep marine blue stones are now generally called "Santa Maria" or "Santa Maria Africana." Other known origins include Sri Lanka, Madagascar, Russia, Pakistan, Afghanistan, and India. A famous special effect is aquamarine cat's eye, which exhibits chatoyancy, but gem-quality examples are rare and not often seen in the market. Therefore, they are almost collector's items. #NaturalStone #PowerStone #Necklace #Ring #Earrings #Pendant #Bracelet #Aquamarine #SantaMaria #Love
