This is a recently new find of opalised fluorite, which I like to call ZigZag tiffany fluorite. It is not the same as Tiffany Stone which is unique to one source in USA. This fluorite has also been called by others; purple jasper or sagenetic fluorite. 
These have a variety of patterns ranging from wispy to zigzags, there is also lots of variety in terms of colour from mostly purple to mostly white, with some including green and black patches. Please decsribe how you would like your point in the customisation box and I will try my bst to find the perfect one for you according to what is available. Please note the points curently available in the 8-9cm size are quite white with swirly patterns. In the other sizes a variety of patterns are available.
