    Seafoam Tourmaline is a member of the tourmaline family.
       
    This rare bluish green tourmaline is mined high in the peaks of the Himalayas. The uncut crystals are often long and thin: the miners call them pencils.

    0.25 carat to 3 carats. Rare large sizes are occasionally found up to 30 carats.
       
    Ovals, cushions, checkerboards, round brilliants, trillions, princess cuts, barion cuts, emerald cuts, and opposed bars.
       
    Seafoam Tourmaline is the exact color of the rough uncovered in the earth. It is not enhanced in any way.
       
    Tourmaline's name comes from the Sinhalese word turmali, which means "mixed." Tourmaline is the most colorful gem variety. Perhaps this is why ancient mystics believed tourmaline could encourage artistic intuition: it has the palette to express every mood. Seafoam Tourmaline has a chameleon-like ability to complement almost every other color, including sorbet shades, earth tones, and vivid brights.
       
    Tourmaline has a Mohs hardness of 7 to 7.5 and is durable and suitable for everyday wear.
       
    Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
       
    $75 to $400 per carat. Rare large gems can be $1,000 per carat.
       
    Tourmaline has unusual electrical properties: crystals acquire a polarized electrical charge when heated or compressed. This property has also made tourmaline the latest miracle ingredient in cleansing lotions: manufacturers say the gem can increase a product's ability to pull pollutants from the pores.
