As described by Tiffany & Co.: "Tiffany proudly named this diamond cut Lucida ®, the brightest star in a constellation. Tiffany’s Lucida ® diamond ring took decades to develop and caused a sensation when it was introduced to the world in 1999. With proud, wide corners, the mixed-cut stone makes a stunning presentation. It commands the eye. Lucida ® is a shining example of perfect proportions."

This Lucida® diamond ring features a smooth platinum mounting, suspending the diamond in a simple 4-prong setting. The diamond weighs 0.80ct and has E color and IF clarity.
