While Tanzanite (Blue Zoisite) and White Topaz may have some inclusions like air bubbles, which are a natural characteristic, the stones used are highly transparent. The blue-violet Tanzanite and White Topaz sparkle. It's a mysterious stone that can appear blue or purple depending on the angle and light. This was custom-made through a semi-order at a jewelry store where you can choose the metal type, and it's carefully crafted. The color appears strongly blue in the photos, but it's actually a lavender color, a pale shade for Tanzanite. Images 15, 17, and 19 are the closest to the actual color. It's in beautiful condition, having been used only once or twice, but it's quite flashy for everyday wear, and I don't have many opportunities to use it, so I'd like to pass it on to someone who will.
