While in a similar color family, Pink Tourmaline and Pink Sapphire are slightly different. To see the difference in color, take a look at HAVERHILL’s Bayberry Grand & Petite 11 Pink Sapphire Necklace. Pink Sapphires are a 9 on the Mohs scale and so are more durable than Pink Tourmaline, which is rated 7.5. We offer Pink Sapphire in the Grand 6 mm stone size and Pink Tourmaline in the Petite 4 mm stone size.
