Tourmaline vs sapphire
Same color family, different stones. Here's how to choose.
Tourmaline
Tourmaline and sapphire are entirely different mineral families. Sapphire is a variety of corundum and rates 9 on the Mohs hardness scale; tourmaline is a borosilicate group and rates 7 to 7.5. Sapphire comes in many colors but each is a single saturation; tourmaline ranges across nearly every color of the spectrum, including bicolor and watermelon varieties unique to the species.
Sapphire
Sapphire is harder, more traditional, and carries significantly higher price points. Tourmaline offers a much wider color palette, including hues sapphire does not produce, at far more accessible pricing. If you are deciding between the two for a colored gemstone, sapphire is the heirloom investment; tourmaline gives you more creative range.
