Cubic Zirconias, also known as CZs, are manufactured gemstones that look similar to diamonds. Cubic zirconia is classified as a diamond simulant - a stone that looks similar to natural diamonds, but is made of different material.

Like diamond, cubic zirconia is naturally colorless. In fact, most natural diamonds have a faint yellow or brown tint. Cubic zirconia is completely clear, comparable to a D color rating.

Diamonds are well-known for their hardness, which ranks at 10 on Mohs hardness scale. For reference, cubic zirconia is an 8.5 on the hardness scale.

At market value, a cut and polished one carat cubic zirconia stone will cost roughly £18 and a similar two carat stone will cost about £26. This is far cheaper than diamonds, which start at £1600 for one carat and increase considerably as size goes up.

Unlike Diamonds, CZ Stones generally only last a couple of years before needing to be replaced. Our stones are all the very highest quality and if taken care of correctly, should last for years before needing to be replaced.
