Cubic Zirconia vs. Diamond Engagement Rings

The saying "diamonds are a girl's best friend" usually rings true when buying engagement rings and anniversary gifts. Diamonds will always be a classic choice for engagement rings, but couples are starting to weigh cubic zirconia (CZ) against them. For some, CZ stones perfectly combine an ideal price point with visual similarity to the diamond. The difference between the two stones starts with the structure and formation. Learn the difference between cubic zirconia and diamond engagement rings  before getting down on one knee.

Cubic Zirconia

Advantages of Cubic Zirconia

  • Available as purely colorless - Since cubic zirconia is a man-made substance, laboratories can create completely colorless stones.
  • Affordable option - A cubic zirconia stone is less expensive than a diamond.
  • Conflict-free - Purchasing a CZ stone from a laboratory lets you avoid any chance of purchasing a conflict diamond.
Limitations of Cubic Zirconia
 
  • Can be damaged - Cubic zirconia isn't as hard as a diamond. CZ stones are not chip-, crack- and scratch-resistant, and can easily break if you drop your jewelry.
  • Not traditional - If you're giving it as a gift to a loved one, you lose the diamond's symbolism of eternal love. Some find it important to stick with the classic diamond for that reason.
  • Doesn't shine as brightly - CZ doesn't sparkle like a diamond does; the CZ stone is more radiant that creates an artificial look compared to the diamond.

Diamonds

Advantages of Diamonds

  • Scratch-resistant - Diamonds are the hardest natural substance on the Earth. Diamonds can be broken by chisels, hammers and drills, but the only everyday item that can break or scratch a diamond is another diamond.
  • Symbol of eternity - Giving diamond jewelry to someone shows the recipient your deep and eternal feelings for them.
  • Magnificent shimmer and shine - Diamonds offer unrivaled shine and fire. This naturally eye-catching stone catches the light like no other gemstone.
Limitations of Diamonds
 
  • Natural imperfections - It's very rare to find a diamond that has no inclusions, or imperfections.
  • Costly option - Diamonds are very expensive. Losing the stone could mean losing a significant amount of money.
  • Potentially not conflict-free - Make sure to ask questions about where the diamond was mined and the I.D. number. The more you know, the better decision you'll be able to make.
