Amazing Natural Sphalerite(.46ct,SI,Spain) hand set and accented with Natural White Zircon(.20ctw,VVS, Cambodia) in 925 sterling silver. Sphalerite is a beautiful gemstone with an unsexy name. Sphalerite has more fire 🔥 than Diamonds, and is actually rare. One of the most relevant optical properties of sphalerite is its high dispersion of light, almost four time higher to the diamond's one (0.156 against 0.044). The pictures don't do this gemstone justice. It's next to impossible to photograph Sphalerite's dispersion. Size 7 can be resized up or down 1 size.
