@gemsofscience: Fresh LuAG facet rough in our most popular shapes and sizes, live now on Etsy! See the link in my profile or go to TurtlesHoard.com LuAG (Lutetium Aluminum Garnet) is a lab created crystal with the same structure as a natural garnet but a crazy composition impossible in nature. With that comes impossibly bright fluorescence along with its snappy yellow-green color, giving it a powerful highlighter-like dayglow effect. We call this type of synthetic gem a 'lumogarnet.' It was created for use in science and medicine, where its incredibly strong fluorescence makes it useful for detecting invisible radiation like gamma and x-rays. It's easy to cut, has hardness 8.5 with no durability issues so it's suitable for rings and has great optical properties. In short it sparkles and glows like nobody's business and makes for stones that reach out and grab people! #luag #gems #garnet #lumogarnet #facetrough #faceting #lapidary #gemstones #green #glow #fluorescent #dayglow #glowing #labcreated #radiology #scintillator #Science #medicine #healthcare #gift
