The only Ripka jewelry I ever bought on QVC was solid gold, real gemstones, and mined diamonds. All the pieces were very detailed, quite well made, attractive, and not overpriced.
I perused the Ripka JTV collection recently, and everything was plated silver, fake stones, and "Bella Luce." The quality is much less than what QVC carried, and the prices are not cheap.
JR also has her own website--the gold pieces there are outrageously high.
I will be passing.
