December – Tanzanite / Zircon / Turquoise/ Blue Topaz

Seeing shades of blue for Decemeber! 

Tanzanite – Named after its geographic origin in Tanzania, tanzanite has quickly risen in popularity since its recent discovery. Tanzanite comes in shades of blue ranging from pale to an intense deep blue with violet undertones. The majority of tanzanite on the market today is heat treated to minimize the brown colors found naturally in the stone, and to enhance the blue shades. The stone measures 6.5-7 on the Mohs scale of hardness. Given its vulnerability to scratch during daily wear, tanzanite is better suited for earrings and pendants than rings.

Zircon- Zircon comes in a wide range of colors spanning from red, orange, yellow, green blue and brown. However, most stones are heat treated until colorless, gold or blue, which are the most popular.  Zircon is the oldest mineral on earth! Since the Middle Ages, people have believed that zircon can induce sleep, ward off evil and promote prosperity. The mining of Zircon dates back 4.4 billion years in Australia, which is, where it is readily found today. It can be found in Thailand, Sri Lanka, Tanzania, Cambodia, Canada and the United States. Though it measures 7.5 of the Mohs scale of hardness, the faceted edges can chip. 

Turquoise - Turquoise is known for its distinct color, which ranges from powdery blue to greenish robin’s egg blue.  The United States is now the world’s largest turquoise supplier. The stone’s popularity here makes it a staple in Native American jewelry. The stone is sensitive to direct sunlight and solvents like makeup, perfume and natural oil.  The hardness only measures 6 on the Mohs scale. 

Blue Topaz – Pure topaz is completely colorless, but it can become tinted by impurities to take on any color of the rainbow! Because of the variety in color, it can often be mistaken for other stones. The most popular color is the vibrant orange, but blue topaz has been increasing over the last several years in popularity. Topaz is a soothing stone that has been said to calm tempers, cure madness and eliminate nightmares. Mostly produced in Brazil, it can also be found in Pakistan, India, Sri Lanka, Russia, Australia, Nigeria, Germany, Mexico and the United States. Measuring 8 on the Mohs scale, it is a rather hard and durable gem, but can be prone to chipping or cracking if not correctly cut
