First of all fire, the sparkly: Signity Star's have more fire than diamonds at .065 dispersion compared to diamonds .044. They are the most brilliant CZ on the market, second to none. They are amazingly white, bright and sparkly.
Why? How is this possible?
Cut: Signity Star's excellent cut is equal to ideal cut diamonds, the best cut for reflection. Their cut is so accurate a star is visible through the top of the crown with a diamond scope. Color: Signity Star is equal to "D" Color of diamonds, the whitest diamond grade. Clarity: Signity Star's clarity is equal to internally flawless, extremely rare diamonds.
