Rauten Rose is a
trade term for a flatback stone with a diamond pattern on top. In glass
it may be fire polished or machine out. As these are acrylic, it is
molded. These are put together doublet-style which accounts for their
depth and iridescence. They are truly gorgeous, look like glass when
set. And you just can't beat this price. 18 x 13mm. Opal Lilac. Sold
by the piece.
