Labradorite (unfortunately not named after man’s best friend, but an area in Canada where it was first found) is one of my favourite gems to date.
Part of the Feldspar family, which also consists of the more well known Moonstone, Labradorite has a beautiful charm about it as you turn the gem to reveal its endearing lustrous metallic tints, from its initial deep, dark and speckled appearance. The iridescence is often green and blue in colour, as you can see from my photos below. Each facet shows a unique display – ideal for bead necklaces, brooches, rings and decorative objects such as carvings, small boxes and ornaments – or for simply swivelling around at the end of class and appreciating the lustre in all its glory.

I love how you can see the hint of iridescence begin to peak at the base, even when it is at its darkest.
A slight swivel begins to reveal the beauty that lies beneath the edge of the gem.
The Labradorite in all of its metallic glory.
