This crystal weighed 3.22 g (16.10 ct) and had a prismatic hexagonal crystal shape. Standard gemological examination confirmed the gemstone to be emerald, and ultraviolet/visible/near-infrared (UV-Vis-NIR) spectroscopy showed a classic Colombian emerald absorp- tion spectrum. -

The value of industrial garnet is unchanged in value from 55,200 t valued at $12.7 million in 2015. influenced by the size and grade of reserves, the type and quality U.S. production of refined garnet in 2016 was estimated to be of garnet mined, the proximity of deposits to infrastructure and 49,400 t valued at $24.4 million, a slight increase in tonnage and consumers, and the milling costs.

Shapiro Feb. 7, 2018 4:12 p.m. ET The fancy color diamond market is on the upswing, according to a report, with blue diamonds seeing the largest gains. Blue diamonds saw a 5.9% increase in value in the fourth quarter of 2017 in a year-over-year comparison, according to data published on Feb. 1 by the Fancy Color Research Foundation (FCRF). Pink and yellow diamond prices decreased slightly in the same period, at 0.8% and 1.8%, respectively. The market overall was up 0.1%. A fancy vivid blue diamond ring (est. $14-18 million) goes on view at Sotheby's on Oct. 13, 2017 in London. ILLUSTRATION: GETTY IMAGES FOR SOTHEBY'S In November 2017, Christie’s sold a 8.67-carat fancy intense blue diamond ring in Geneva, Switzerland for $13.2 million. The reason for this disparity has less to do with demand, than it does with the rarity of the stone, says FCRF Chairman Eden Rachminov. Demand for yellow and pink diamonds is actually higher, but the amount of blue diamonds being mined is decreasing. “Almost nothing is coming out of the ground,” he says. Pink diamonds have seen the highest gains in the last 13 years with an overall appreciation of 361.9%, according to FCRF’s index, which is compiled through survey data provided by manufacturers and brokers. -

Diamonds & Emeralds & Rubies, Oh My: Gem Lore in Baum's Wonderful
Diamonds and Emeralds and Rubies, Oh My: Gem Lore in Baum's The Wonderful World of Oz From the ruby-studded land of the Quadlings to ubiquitous references to glittering emeralds and diamonds, gemstones play a crucial role in Baum’s iconic Wonderful World of Oz. For over a century, critics have focused primarily on biographical and allegorical explanations for the choices of specific gems and metals without thoroughly exploring other possibilities. Instead, a bimetallic discourse on gold and silver introduced in the 1960s has been accepted as fact by academics and readers alike, as have gem choices linked to everything from Baum’s birthstone and Irish roots to Chicago’s Crystal Palace. I propose to take a new, archetypal approach, arguing, by contrast, that the selection of emerald (rather than, for example, topaz) as the featured gemstone links Oz to centuries of mythology. An examination of alchemy and its cultural influences, as well as Baum’s undisputed belief in Theosophy, furnish additional connections. Thus in nearly all ancient and sacred thought, esoteric gem lore has traditionally played integral roles in life and religious beliefs. A connection between emeralds and vision, for example, is associated with the Emperor Nero, Apostle John, Pliny the Elder, and even Napoleon. Moreover, this connection between the emerald and the human eye, which plays such a prominent role as the Emerald City where everyone must wear locked-on green goggles, has its roots in the Hindu Vedas, Sanskrit mantras, the Koran, and Judeo-Christian beliefs. This substantial precedent is echoed in the history of ruby lore and the connection of the red stone to female rulers who possess ruby thrones and a ruby-encircled cap (Glinda) to a ruby palace (Gaylette). -
