Simulated

First, simulated stones are those materials which look like a real gem but are not made of the same elements and materials. Thousands of years ago Egyptians were able to produce a blue opaque glass similar in color to turquoise.

Just like "Water" is also known as H20, "Oxygen" is also known as O2, and "Hydrochloric Acid" is also known as HCl, "Simulated Diamonds" (or at least by far the most popular form of them) is known as Cubic Zirconia, or CZ.
