Lllanite is a stone comprised of multiple minerals. It is primarily a Rhyolite with spots of pink Feldspar and blue quartz. Although it is formally known as Llanite, it is also sold under the trade names of Que Sera stone and Vulcanite. It is a scarce stone, and it is difficult to find online, so if you find some while you are rock shopping – consider buying some to add to your collection. Brand New from my boutique, Studio Rox. Non-smoking, no cat home. We do have Great Danes, but we don't allow them to play with crystals. Shop with confidence - I am a multiple year Posh Ambassador II with an average same day ship time & 5 star rating!
