Cocktail rings — first popular in the 1940s and 1950s as a way to show off at cocktail parties —are staging a comeback this holiday season. The rings, which sport big colorful gems, can be found everywhere, real and fake, from Tiffany's to Macy's and even at Walmart.com. Ravi Jariwala, a spokesman for Walmart.com, says the site expanded its selection from about 10 last year to more than 30 this year to keep up with the trend. "This season there's a pretty strong customer response," said Jariwala, noting sales have more than doubled from last year.

A top seller is a cushion-cut square ring made with either blue topaz, pink sapphire or amethyst surrounded by "diamond accents," which retails for $79.97. Prices range from $59.88 for a pink sapphire three-stone ring to $1,590 for a fancy-yellow grade and white diamond ring. At Macy's, cocktail rings are offered both in its fashion jewelry and fine jewelry departments. "We have some great styles in fine jewelry featuring rubies and various stones," said Macy's spokeswoman Elena Kazan. "A lot of them are very Deco-inspired." Big sellers are Levian brand rings with sapphire and topaz, Kazan said. Prices range from about $300 to $9,000 dollars
