Journalists have known for decades what anyone who tries to do so finds out pretty quickly: it’s hard to sell a diamond for anywhere close to what you paid for it. But if you need cash and fast...what’s to do? Enter CubicZirconia.com's "Diamond Downgrade" program, which allows you to keep your jewelry, just sell the diamond for fast cash at a fair price, have it replaced with our 5A/AAAAA cubic zirconia...and be assured that no one will ever know the difference.

Sterling silver will tarnish more/more often over time than 10 karat gold, which is more susceptible to tarnishing than 14 karat gold. 14 karat gold is itself more likely to become tarnished than 18 karat gold. Here's why...and what it means to you as a jewelry buyer.

Diamonds are universally measured against the “4C’s standard”: Cut, Color, Clarity and Carat Weight. All these characteristics can also be found in top-quality cubic zirconia stones, such as those manufactured for use in our CubicZirconia.com finished jewelry and sold through our website. In this blog post, let’s discuss how these two stones compare. The more perfect the diamond, the harder a jeweler has to work to determine if it's really a diamond...or one of our cubic zirconia stones!

In addition to being the most popular clear natural diamond substitute in the world over the last few decades, cubic zirconia is also an extremely viable colored gemstone and birthstone simulant.
