  • Preliminary Investigation of Purple Garnet from a New Deposit in Mozambique
    GIT GEMSTONE UPDATE Preliminary Investigation of Purple Garnet from a New Deposit in Mozambique By GIT-Gem testing laboratory 11 May 2016 Introduction In March 2016, a group of Thai gem dealer led by Mr. Pichit Nilprapaporn paid a visit to the GIT and informed us about a new garnet deposit in Mozambique, that was discovered near the western border with Zimbabwe. They also displayed a large parcel of rough and a few cut stones claimed to be the material found in this new deposit (Figure 1). According to the stone’s owner, these garnet specimens were unearthed from an unconsolidated sediment layer, just a few meters below ground surface. This brief report is our preliminary investigation on the interesting vivid purple garnet from the new deposit in Mozambique.

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.

  • Gemstones in Metal Clay
    Gemstones in Metal Clay Many natural gemstones can be set into metal clay and fired in place. Other gemstones will not survive the heat of a kiln and should be set after firing. These charts show the results of kiln and torch tests that have been performed on both natural and synthetic gemstones, adapted with permission from the original testing by Kevin Whitmore of Rio Grande. This information is for reference and should be used as a guide. There is always some risk of losing a natural gemstone even if others of it’s kind have survived in the past. Gemstones may have internal flaws that can be liquid or gaseous filled, or contain crystals of other materials that can cause the gemstone to fail where it usually does not. This guide aims to help metal clay artists sort out gemstones that are known to survive under fire from those that are not. Gemstones are minerals that are classified into groups based upon the constancy of their major properties. Each mineral family has one or more varieties contained within the group. When we sort the tested gemstones according to their mineral group, it becomes clear that an easy way to gauge the survivability of a gemstone is to look at the results of other varieties within that same group. Aquamarine and emerald, for example, are both varieties of the beryl group of minerals. The result of tests done on aquamarine and emerald indicate that minerals in the beryl group will not survive kiln heating. There are exceptions, as there always are in the natural world, but in general this method can be reliable for many varieties.

  • Gem-Quality Chrysoprase from Haneti-Itiso Area, Central Tanzania
    GEM-QUALITY CHRYSOPRASE FROM HANETI-ITISO AREA, CENTRAL TANZANIA KARI A. KINNUNEN and ELIAS J. MALISA KINNUNEN, KARI A. and MALISA ELIAS J., 1990: Gem-quality Chrysoprase from Haneti-Itiso area, Central Tanzania. Bull. Geol. Soc. Finland 62, Part 2, 157—166. Gem-quality, apple-green, Ni-bearing chalcedonic quartz occurs as near-surface veins in silicified serpentinite in the Haneti-Itiso area, Central Tanzania. AAS de- terminations revealed a high Ni content, 0.55 wt.%, and low Co and Cr contents of 120 and 1 ppm respectively. NAA determination revealed near chondritic REE contents. X-ray diffraction determinations showed that the Chrysoprase consists main- ly of alpha quartz with some opal-CT. The gemmological properties are: refractive indices from 1.548 to 1.553 (±0.002), mean specific gravity 2.56, hardness about 7 on Moh's scale, inert to ultraviolet radiation, green through Chelsea filter, and absorption in the deep red and violet part of the optical absorption spectrum. The results confirm the identity of the material as Chrysoprase. Microscopically the Tanzanian Chrysoprase consists of spherules which are high- ly disordered, concentric, and composed of bipyramidal quartz, chalcedony, quart- zine, and opal-A. They were classified into four main types according to the shell arrangement. The diameter of the spherules ranged from 40 um to 77 um. Fluid inclusion types in the bipyramidal quartz were monophasic, low-temperature type. The spherules, silica types and REE contents suggest that this Chrysoprase was deposited by evaporation of surface waters connected with the silicification of the serpentinites. Genetically analogous formations, common in Africa, include M-fabric type, weathering profile silcretes.
