Enhancement: Seafoam® Tourmaline is the exact color of the rough uncovered in the earth. It is not enhanced in any way.
Lore & History: 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.
Toughness & Hardness: Tourmaline has a Mohs hardness of 7 to 7.5 and is durable and suitable for everyday wear.
Care & Cleaning: Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
Price Range: $150 to $800 per carat. Exceptionally fine gems can command even higher per carat prices..
Special Characteristics: 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.
