   What makes a diamond brilliant?

   The cut determines just how much "fire" a diamond has.  Not all diamonds are cut the same.   We sell only the finest diamonds cut to strict standards. All round Brilliant diamonds are Premium or Ideal Cut.

  
Ten Facts You Need to Know Before Buying a Diamond

1.  Never compromise on the cut. Cut determines the brilliance of a diamond.

3.  Stick to the Pricelist.
