This beautiful syenite looks like a black Labradorite and has a grey/black background with a chatoyant grey-blue flash. It contains small crystals of feldspar which give the gorgeous sheen. It tends to be machine-cut and drilled for consistent size and shape and is sometimes stabilized.
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.
