Gemstone: Green "Opal" is a trade name for a green and brown Chalcedony. This durable stone has rich moss-like tones and unique inclusions, a polished luster and smooth surface
Synthetic: Also known as "Opalite," these man-made glass beads have an amazing opalescence with a slight blue tint and translucent to semi-opaque appearance. Colours may vary.
Our Semi Precious Stones are genuine and natural unless they are stated to be synthetic in the description. However, you will find the vast majority of Semi Precious Stones are treated in some way, as they would not be stable enough for use in jewellery in their original state.
