Years ago I used to see a lot of Judith Ripka fine jewelry in department stores like Bloomies, but I found the prices to be rather high and she often used man-made stones.
Her silver jewelry always did the best on QVC, and she was able to offer pieces that were similar to her couture line, but at a much lower price.
Personally I never purchased any of her line UNTIL she began to carry gold here on the Q. There were some fair prices during sale times, and all of her gold jewelry featured genuine stones, including pretty decent diamonds. I think her heavier-weight and more expensive pieces were the best--exquisite design with a lot of intricate detail, strong construction, good gold weight, attractive stones, and very unique settings and closures.
She really did love to come on the Q and explain her design process. (She was known as the Queen of Hearts for all her heart diamond details, which then morphed into "cherries.")
About the same time, Judith started a more budget-friendly line of gold jewelry at the department store Lord & Taylor. However, her pieces did not sell well, and sadly, the department store permanently closed.
To me, some of the newer pieces that are being marketed on the Judith Ripka website resemble more the simpler Ripka line than her previous QVC creations.
My favorites will always be the more traditional and fanciful gold elaborate designs, but they can be more costly, and I do not think there was a big market for them, especially among younger generation shoppers.
Some people sell out but still keep a toe in the water, like Isaac. I know she had a great career, and now she is probably enjoying her retirement with her many millions.
Because Xcel owns the intellectual property rights to these vendors, they can basically design what they want, but there is a definite difference when the founding creative artist exits the scene.
