Bigger is better especially in DiamonUltra™ cubic zirconia and platinum over sterling silver. A brilliant 6-carat round is crowned by a double-level halo of smaller brilliant-cut stones that form a radiant square and continue down the shank. The twinkle factor is off the charts due to its elevated design which allows optimum light refraction. 7.28 carats T.W. Platinum over sterling silver. Sizes 6-10. (Carat weights may vary by plus or minus 5% of stated weight.)
