Judith Ripka's "Flora" design features a bezel-set doublet in a rope-y mounting with twenty-four cute little CZ ("Diamonique") bubbles bubbling up and onto the stone.   

A doublet is two stones glued together to achieve some sort of effect.  For example, an opal doublet is a thin sliver of opal material glued to a piece of rock (or sometimes hard resin)  that allows you to get the effect of opal without the price.

With these Flora rings, faceted quartz or glass is layered on top of a flat slice of something-or-other to get an ethereal, sparkly and shimmery look.  I don't actually know what the white flat slice is this case, though I suspect it's either mother of pearl, moonstone or man-made.  

The face of the ring is 20mm (just over 3/4") tall and 16mm (5/8") wide.  The shoulders taper from 5.5mm to 3.3mm in the back, where the band is plain, allowing for resizing.  Currently the ring is a size 5.

The inside of the band is stamped "CZ THAILAND" and "JUDITH RIPKA 925."

This ring weighs 12.4 grams.
