Many celebs believe in the healing, protective properties of crystals.
Including Robin Thicke, who allegedly dropped $20,000 on a two-foot high Amethyst stone at Crystalarium in West Hollywood
The Amethyst stone is regarded as the stone of 'faithful love' and carries 'the energy of fire and passion.'
Thicke has made no secret of his mission to win over his former high-school sweetheart, so we can only assume this is why he bought this stone!
