If you or a loved one has a December birthday, consider a gift of tanzanite or turquoise for the holidays or their birthday, two of December’s striking blue-toned birthstones.

Here are some rare and interesting facts about these festive gemstones.


  • Tanzanite is named after the East African state of Tanzania, the only place in the world where it can be found.
  • The blue variety of tanzanite is called zoisite.
  • Tanzanite comes in a rich blue tinged with purple hues.
  • Tanzanite ranks 6 or 7 on the Mohs scale, meaning it has fair to poor toughness. It should not be set in a ring that will be worn during strenuous activity.
  • Never clean tanzanite in an ultrasonic cleaner.
  • Tanzanite was found in 1967 and is a relatively recent discovery. The gemstone was offered to Tiffany & Co.
  • Originally known as blue zoisite, the mineral’s name was changed to tanzanite—the place where it was found—by Henry Platt, Vice President of Tiffany & Co., because he felt zoisite sounded too much like suicide.
  • In October 2002, the American Gem Trade Association officially named tanzanite as the third December birthstone (the other two are turquoise and zircon).
  • In the 1997 movie, Titanic, the beautiful heart-shaped blue pendant necklace that Kate Winslet wore called the “Heart of the Ocean” was in fact a tanzanite stone surrounded by diamonds.


  • Turquoise is a blue-green mineral, with the chemical name of hydrated copper aluminum phosphate.
  • The gemstone’s blue color can be attributed to the presence of copper while the presence of aluminum adds a greenish hue to the gem.
  • With a rating between 5 and 6, turquoise should be handled carefully and stored separately from other harder gemstones.
  • The word turquoise is derived from the Old French word meaning Turkish stone.
  • The ancient Egyptians used turquoise in jewelry, art, ornaments, and statues because they believed it had magical powers.
  • Some of the finest turquoise is known to come from Iran, but high-grade turquoise is also mined in Arizona and New Mexico.
  • Turquoise is sacred to many Native Americans. In the past, Native Americans would use it as a shaman’s stone, which were stones believed to have strong metaphysical properties for spiritual growth.
  • It takes millions of years and the right conditions for turquoise to be formed when water enters an iron-rich limonite or sandstone that contains copper, aluminum, and other minerals.
  • Turquoise may contain narrow vein-like markings of its host rock. These markings are known as the matrix. Limonite creates a dark brown marking while sandstone creates tan markings. The presence of a matrix can lower the value of a turquoise.
