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.
2.  Consider only certified diamonds by independent labs like GIA.
3.  Stick to the Pricelist.
4.  Fluorescence -- what is good and what is bad.
5.  Be aware of treated diamonds -- clarity or color enhancement.
6.  Only buy loose diamonds. None of the 4 C's can be determined in a setting.
7.  Deal only with established reputable companies with available showrooms where you can view and study diamonds.
8.  Avoid "sales" and other gimmicks.
9.  Know the return policy.
10.  Know the upgrade policy.

Stick to the Facts.
