The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. Because close visual likeness to diamond, cubic zirconia has remained the most important competitor for diamonds since commercial production began in 1976. All our tiaras are "hand set" with genuine CZ stones. We offer the most spectacular and well made CZ tiaras in the world!
