Large Polished Labradorite Freeform
Located in Wormelow, Herefordshire
A spectacular large polished labradorite freeform sourced from Madagascar. Characterised by its iridescent colours, principally blue, this huge high grade labradorite is a stunning specimen, the lustrous colours fluctuating as it is observed from different angles. It is freestanding, making a striking sculptural piece for an interior, with a polished face to one side and a naturalistic reverse.
Labradorite is named after the region of its discovery at Paul Island in the Canadian province of Labrador, first discovered here in 1770. Madagascar is currently the main source of labradorite. To expose its stunning colours, the stone is highly polished, revealing its natural beauty. This in itself is a talented skill, with only a small percentage of labradorites yielding positive results, making this specimen a rare discovery.
We also have two other large labradorite...
