The Fabulous Jewelry Fashions of Fall/Winter 2007
The Fabulous Jewelry Fashions of Fall/Winter 2007 Natural Stones When you want to keep it soft, go with the buff and polish of genuine mother-of-pearl, aventurine, wood, jasper and freshwater pearls. Geometrics Edgy circles, squares and triangles take gold and silver metals from playful to sophisticated. They should figure prominently in your accessory wardrobe from work to weekend. Hammered Texture You can’t beat it. From beads to bracelets it’s hot, hot, hot -- especially in matte gold. Texture of all kinds is in the forefront right now. Green Even jewelry is showing its “organic” side this fall. Cultivate the green trend in leafy tones that go it alone or mix with the sparkle and brightness of multi-colored crystals and beads. Two-Tones Your best bet for career and travel. The marriage of gold and silver offers the ultimate in ver - satility. This season look for more matte finished combos and even matte and polished finish - es hanging out together. Jewel Tones All those neutral fashions are begging for a power surge of color -- in accessories that take mix and mingle to the extreme. Cut crystals and CZ’s lead the parade. IMPORTANT THINGS TO KNOW ABOUT OUR COLLECTION: *All of our pierced earrings have stainless steel posts (surgical steel) and stainless steel butterfly clutches. The posts are notched, so that the clutch - es stay on tight. *All of our silver jewelry has a Rhodium finish unless otherwise specified. Rhodium will not tarnish or discolor. Your customers will find the finish will stay as nice as the day they bought it. -

Supporting Contemporary Makers
Supporting contemporary makers Acquisitions for the Goldsmiths’ Company Collection 2019–2020 Dr Dora Thornton Supporting contemporary makers: acquisitions for the Goldsmiths’ Company Collection 2019–20 The Goldsmiths’ Company has supported excellence, craftsmanship and skills in the goldsmiths’ community ever since the Company received its first Royal charter in 1327. The Company now has one of the finest collections of British silver, including contemporary and historic plate, modern jewellery and art medals. Much of the Collection is still used for its original purpose. Jewellery is worn at occasions in the Hall. Pieces are also displayed in exhibitions and lent elsewhere, as well as being used for teaching the next generations of makers, our apprentices at the Goldsmiths’ Centre, and promoting wider knowledge and patronage of the craft. Our ambitious plans to digitise our collections will eventually make much of our material—objects and archives—freely available online through our website to show who we are and what we do. This booklet describes the Company’s acquisitions, which are overseen by the Contemporary Craft Committee, over one year, from April 2019 to April 2020. Many of the purchases—and one commission—are the work of makers who are new to the Collection. Commissions completed this year include a superb brooch; two very different portrait medals of Prime Wardens of the Company; and three Court Cups, designed to be used by individual members of the Court of Assistants in the Hall. The cups are paid for by the Company and since 2018 have formed part of the Collection; they advertise the work of particular makers and excellence in the trade while also recording much about their individual patrons. -

Fluid and Solid Inclusions in Host Minerals of Permian Pegmatites from Koralpe (Austria): Deciphering the Permian Fluid Evolution During Pegmatite Formation

Although pegmatites suffered intense Eoalpine high-pressure metamorphic overprint during the Cretaceous period, the studied samples originate from rock sections with well-preserved Permian magmatic textures. Magmatic low-saline aqueous FIs in garnet domains entrapped as part of an unmixed fluid together with primary N2-bearing FIs that originate from a host rock-derived CO2-N2 dominated high-grade metamorphic fluid. This CO2-N2 fluid is entrapped as primary FIs in garnet, tourmaline, and quartz. During host mineral crystallization, fluid mixing between the magmatic and the metamorphic fluid at the solvus formed CO2-N2-H2O–rich FIs of various compositional degrees Citation: Krenn, K.; Husar, M.; that are preserved as pseudo-secondary inclusions in tourmaline, quartz, and as primary inclusions Mikulics, A.
