emerald-green and pink YAG, colorless and colored sapphires, citrine
Alexandrites, emeralds, and sapphires cut
from laboratory grown crystals have the same chemical composition, hardness, and other
basic physical properties as the corresponding natural gemstones, but are cleaner, more
perfect stones. Cubic Zirconia (CZ) does not have a corresponding gemstone that
occurs in nature. CZ is usually sold as a diamond look-alike, but can be made in a
variety of colors such as the ones we offer here. YAG also does not have a counterpart in
nature, however its crystal structure is similar to that of natural garnets (hence the
name yttrium aluminum garnet).
