We use only the finest AAA grade Diamondeau? - flawless simulated diamonds to make our fabulous jewlery. These magnificent gemstones are cut and polished in exactly the same way as any mined Diamond. They rate so highly on the Mohs scale of hardness that they can even cut glass like a mined Diamond and to top all that they have even more inner fire or sparkle than mined Diamonds. We have mounted just over 11 carats of round Brilliant and square Princess cut stones into mounts of the finest 925 Sterling Silver. The necklace features a double strand chain and measures 17.5 Inch with a 2 Inch extender. Purchase the set to get the earrings for an extra saving.
