Pure Pink Topaz is a natural topaz, mined in Brazil, and it has been Titanium treated in much the same manner (and by the same people) as the Mystic Fire Topaz I've sold online for 6-7 years now.  This is a very stable process, and you don't ever have to worry about the color fading.

This well built ring holds a very pretty stone.  It weighs about 1.5 carats, and measures 8x6 mm.   A good, solid, everyday ring -- and would look just as nice out on the town!
