6.73ct Tanzanite and Chalcedony Brooch

PRICE ON REQUEST

This is a bold and beautiful brooch, designed to create drama whenever it is worn.

The architecture of this stunning chalcedony carving by Steve Walters is an incredible place to begin this exceptional brooch. A single exquisite diamond accents the carving perfectly. The dangling (and removable) 6.73ct tanzanite is a richly saturated blend of purple and deep blue which exhibits rich flashes of red; this is exceptional material, rarely available today. The tanzanite is set with another triangle shaped 0.20ct diamond, in 18kt and platinum.

The hand-fabricated 18kt mounting is masterfully executed, and compliments the sculpture perfectly. If so desired, hardware to make this wearable on a necklace could easily be added.

  • Black Chalcedony (natural, carved by Steve Walters)
  • 6.73ct Tanzanite
  • 0.40ct of Diamonds
  • 18kt Gold and Platinum
  • approximately 70mm x 37mm (2.76" x 1.46")
  • wearable as a brooch
  • made in the USA by Dalan Hargrave for ART Guyon    

ABOUT THE GEMSTONES    

Chalcedony is an amazingly rich and diverse family of gemstones. Naturally colored black chalcedony is quite rare, and difficult to source today. For more information, CLICK HERE

Tanzanite is among the most fascinating of the modern gemstone discoveries. Tanzanite was discovered in the Merelani Hills (at the base of Mt. Kilimanjaro in northern Tanzania) in 1967, and this remains the only place in the world this unique gemstone is found. Tanzanite is a variety of the mineral zoisite, and there is lively debate in the gemstone community whether the word tanzanite should be used to describe all gem quality zoisite from Tanzania, or exclusively in reference to the blue-violet class of material. 

Tanzanite crystals exhibit strong pleochroism, which means that distinctly different colors are shown as you turn the stone to different angles. The finished color of the gemstone depends on how a cutter orients the original material. At Cynthia Scott Jewelry, I am strongly drawn to cut tanzanites which clearly exhibit pleochroism as the stone faces up. I eagerly seek out stones which will show blue and violet with flashes of red; in my personal opinion, these stones most clearly showcase one of the properties which makes tanzanite special. 

Tanzanite crystals are initially sorted based on the intensity of color saturation; this is a gem in which the deepest saturations of color are the most highly prized. Interestingly, tanzanite is one of a handful of gems which requires larger body size in order to achieve the lush and velvety saturated tones for which it is famous.
