Think Blue.  Beautiful Blues.

Tanzanite is the exquisite blue-purple variety of the mineral zoisite that is only found in one part of the world. Named for its limited geographic origin in Tanzania in the foothills of Mount Kilimanjaro, tanzanite has quickly risen to popularity since its relatively recent discovery; it is rarely pure blue, almost always showing its signature overtones of purple.

Zircon is an underrated gemstone that is often confused with synthetic cubic zirconia due to similar names and shared use as diamond simulants. Few people realize that zircon is a spectacular natural gemstone available in a variety of colors.  The most popular colors are vivid blue and bright Caribbean Sea colors.  In the Middle Ages, Zircon was said to aid in resting, bringing prosperity, honor, and wisdom to its owner.  Its beautiful colors, rarity and affordability make it a popular acquisition!

Admired since ancient times, turquoise is known for its distinct color, which ranges from powdery blue to greenish robin’s egg blue. It is one of few minerals to lend its name to anything that resembles its striking color.  The word “turquoise” dates to the 13th century, drawing from the French expression “pierre tourques”, which referenced the “Turkish stone” brought to Europe from Turkey.  Ancient Persia (now Iran) was the traditional source for sky blue turquoise gemstones. This color is often called “Persian blue” today, regardless of its origin. The Sinai Peninsula in Egypt was also an important historical source of turquoise gems. The U.S. is now the world’s largest turquoise supplier. Nevada, New Mexico, California, and Colorado have produced turquoise, but Arizona leads in production by value, as well as quality. The stone’s popularity here makes it a staple in Native American jewelry. Turquoise is found in arid regions where rainwater dissolves copper in the soil, forming colorful nodular deposits when it combines with aluminum and phosphorus. Copper contributes blue hues, while iron and chrome add a hint of green.
