They do come in several colors, and they can be cut into the same geometric shapes as diamonds. They first hit store shelves in the 1970s, providing consumers an affordable option for diamonds. After heating zirconium oxide, crystals form. Manufacturers melt zirconium oxide with stabilizers and heat it to nearly 5,000º F. Instead, manufacturers produce them in labs using zirconium dioxide. As a result, they are more durable and scratch-resistant.Ĭubic zirconia is not a naturally occurring stone. Fortunately, more jewelers are covering cubic zirconias with protective coatings. Cubic zirconia produces more rainbow flashes of light compared to diamonds. They are comparable to diamonds because they are clear stones that reflect light well.

Cubic zirconia will emit a rainbow of light, but not at the extreme that diamonds show light. If you have a diamond, it should sparkle brilliantly.

Designers cut diamonds with facets to reflect the light. Their beauty and versatility are why they adorn engagement rings and serve as the April birthstone. These beautiful gemstones are durable, customizable, and fashionable. ![]() Because diamonds also have a beautiful luster and refraction, they have become iconic gemstones, too. Its structure makes diamond the hardest natural substance on the planet.ĭiamonds are chemical-resistant and have high thermal conductivity, making them popular tools in manufacturing.
