Cubic Zirconia (CZ):  Is the Cubic Crystalline form of Zirconium Dioxide (ZrO₂).  This synthesized material is almost as hard as a Real Diamond (Note: Diamonds are the hardest naturally occurring substance found on earth).  A Cubic Zirconia has a rating of approximately 8.5 on Mohs’ Diamond Hardness Scale vs. a rating of 10 for a Real Diamond; a CZ is Optically Colorless & Flawless where a Real Diamond is rarely Colorless or Flawless.  By comparison, a Cubic Zirconia is entirely Colorless: equivalent to a perfect "D" on a Real Diamond Color Grading Scale.  A Cubic Zirconia has NO Interior Inclusions or Surface Inclusions like a Real Diamond might have.  Because of their Low Cost, Durability, & Close Visual Likeness to a Real Diamond, synthetic Cubic Zirconia has remained the most geologically & economically important competitor to Real Diamonds since commercial production began in 1976.  When a Real Diamond & a Cubic Zirconia are shown to a customer side-by-side for the very first time most people picked the Cubic Zirconia thinking it’s the Real Diamond because a Cubic Zirconia has a much Higher Brilliance & Reflective Quality than that of a Real Diamond.  A Diamonds reflectivity is 0.044 while a CZ’s reflectivity is 0.066.  Also, Cubic Zirconia are currently on average 125 to 2,300-Times Cheaper than the cost of a Real Diamond & finally, our Cubic Zirconia are actually mounted in some of the same bands that our Real Diamonds are set in.  A cut and polished round 1.0 Carat cubic zirconia stone will cost about $20.00 & a similar round 2.0 Carat CZ will cost about $30.00.  Where as, a cut & polished 1.0 Carat diamond currently starts at around $2,480.00 to $4,150.00 & a similar 2.0 Carat diamond will start at  $9,630.00 to $69,830.00 depending on its cut & grade & as diamond sizes increase their price gets exponentially more expensive.
