Tanzanite, the December birthstone. The vibrant blue-violet color is a hue that only natural, untreated tanzanite can achieve♡ More rare than diamonds, and with the Merelani mine's depletion, its value continues to increase, without decreasing, making it a gemstone of increasing rarity☺︎ A certificate of authenticity will be included with your purchase♡ (Chinese and English) Items will be carefully packaged and shipped. If you prefer, we can change to Yu-Pack delivery, so please feel free to let us know in the comments. We also offer combined shipping discounts◎ Natural stones are photographed indoors under natural light and fluorescent lights. We do not use image filters or color adjustments because we want to accurately convey the inclusions, cracks, and colors created by nature. The stone sizes are listed as they were at the time of purchase. If you have any questions about a stone, please feel free to ask in the comments♡ ※ Natural stones that are not design bracelets will be in the same condition as when purchased. If you would like to have the inner rubber changed, we can replace it with four layers of domestic Operon rubber for an additional ¥200. In that case, the size can also be made smaller. (The extra stones will of course be included) Please feel free to ask in the comments♡ All stones are carefully selected and sourced from professional natural stone suppliers. We hope these stones find their way to those who need them. #Tanzanite #CertificateOfAuthenticity #NaturalStone #NaturalStoneBracelet #HighQuality #Bracelet #Mysterious #Witch #Crystal #PowerStone
