Tanzanite is relatively rare and costly, occurring in only one place in the world, the Merelani Hills in Tanzania, East Africa. It was discovered in 1967 and is named for its country of origin. Tanzanite belongs to the Zoisite family, and its official name is ‘Blue Zoisite’, but the jewelry store Tiffany and Co. unofficially renamed it ‘Tanzanite’ a short time after its discovery to improve its marketability. Tanzanite is now the common name used commercially around the world.
Tanzanite is a blue stone which ranges from transparent to slightly opaque, and ranges in color from deep ultramarine blue to light violet-blue. The most coveted crystals are blue with a hint of purple around it. In raw form Tanzanite occurs as blue, purple, brown and yellow. Nearly all Tanzanite is heat-treated to produce the striking violet-blue color and to remove the brownish yellow areas. Tanzanite is not especially durable and should be worn with care.
Tanzanite is said to be of benefit to workaholics, and to those who are overworked, as it is thought to calm an overactive mind, to relax you and to slow you down and encourages clear communication. Tanzanite is believed to facilitate a higher consciousness and stimulate intution and perception, as well as helping to be more self aware. It is also said to enhance psychic abilities and to open the heart, elevating the mood and bringing feelings of peace.
We have all heard of the 4 Cs of diamonds, but what about the 5th and most important C? (Cost)
Every diamond is a miracle of time and place and chance. Like snowflakes, no two are exactly alike.
Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.
The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase. Now, with the addition of the 5th C, cost, people will have a greater understanding of value when it comes to loose diamonds.
These custom pendants were made for a customer who is a part of the United States Border Patrol Tactical Unit or BORTAC. He wanted them made for his wife and mother to let them know that he will always be with them. BORTAC is the tactical/special response arm of the United States Border Patrol. The mission of BORTAC is “to respond to terrorist threats of all types anywhere in the world in order to protect our nation’s homeland.” Since its inception BORTAC has steadily expanded its scope and mission capabilities, and is now a rapid response unit capable of executing both foreign and national level domestic operations. Their missions have included international training/advisory functions, counter terrorism operations, counter narcotics operations, high-risk warrant service, dignitary protection, interdiction & patrol operations, and tactical training to other U.S. agencies and military units.
This custom orange diamond ring was inspired by the red fox. It was a request of a husband whose wife absolutely loves foxes. To incorporate the red fox’s color, we chose a natural fancy vivid yellowish orange diamond for the center stone. We brought out more of the fox with it’s paw prints down the sides, along with 12 white diamonds, all crafted in 14k white gold. Both husband and wife were thrilled with the outcome of this unique custom piece.
The red fox is the largest of the true foxes and is well-known for its large bushy tail, which is often tipped with white. The red fox’s tail, which is known as a brush, can be used as a warm cover in cold weather. With 28 different vocalizations, red foxes have a wide vocal range that spans 5 octaves. Even though they have so many sounds, how is it that we still don’t know what the fox says?
“The Pink Star,” a 59.60-carat colored diamond. The oval-cut stone, the largest internally flawless fancy vivid pink diamond ever graded by Gemological Institute of America (GIA), sold for $83 million — a record for any gemstone at auction — when was auctioned by Sotheby’s in Geneva on Nov. 13. It was estimated to raise more than $60 million.
Isaac Wolf, a New York-based diamond cutter, was the buyer of ultra rare pink diamond last night. Wolf renamed the oval-cut stone the “Pink Dream,” New York-based Sotheby’s said. He competed against three others for the gem in bidding that lasted about five minutes before the strike of the gavel, followed by cheers and applause.
Until the 1980s, Champagne color diamonds were virtually unheard of, but thanks to Rio Tinto, they’ve bubbled up to become the gem world’s shining stars.
Although brown diamonds were among the earliest gems used for handmade jewelry—found in Roman rings dating back to between the first and third centuries—in modern times, they’ve suffered from a serious image problem. Long scorned as low-grade and undesirable, they were primarily relegated for use in industrial purposes rather than in jewelry. And this would undoubtedly still be the case were it not for the efforts of Rio Tinto, owner of Australia’s famed Argyle Diamond Mine.
Reinventing the Brown Diamond
With its yield of 35 million carats of diamonds per year, Argyle accounts for about one-third of global production of natural diamonds; however, about 80 percent of Argyle diamonds are brown. After making this discovery in the mid-1980s, rather than write off all those stones as subpar, Rio Tinto decided to rehabilitate the color diamond’s image.
The first and most important step was to shuck the traditional, drab “brown” label and trade it in for something with pizazz: “Champagne” for lighter colored stones, “cognac” for darker, richer tones.
Next, the company inaugurated its World Jewelry Design Competitions. Over the years, Rio Tinto’s global design contests have increasingly become more prestigious and high profile—its most recent one attracted entrants from the U.S., Canada, Australia, India, China and Hong Kong, and its top designs were showcased in a suite at the 2012 Academy Awards.
A Measure of Color
Another significant strategy in Rio Tinto’s effort to elevate the status and profile of natural color diamonds was the development and introduction of a new, internationally accepted grading system, as these natural color diamonds are excluded from the traditional GIA scale. The Argyle scale rates Champagne diamonds on a scale of C1 (representing the lightest Champagne color) to C7 (representing the darkest, most intense hue—fancy cognac).
The company also launched an extensive trade campaign, providing sales training and promotional materials to retailers, and created the website champagnediamondcenter.com, to help spread the word.
These efforts have paid off handsomely, with more manufacturers and retailers using Champagne diamonds as part of their standard offerings. Once considered humble, Champagne diamonds are now associated with status, good taste, romance, and the finer things in life.
