Bring on the bling! A step-by-step guide to achieving expert color-work with fabrics to create dynamic, glittering gemstone-themed quilts Quilting expert Andrea Tsang Jackson guides readers through transforming the beauty, allure, and power of natural stones into glittering complex patchwork quilts. She provides a master plan for the color work required to achieve effective transparency and light with fabric selection. Readers will be able to paper piece their way to a jewelry box of blocks. Beginning with nine traditional gemstone shapes, such as teardrop, marquis, and emerald cuts, each block progresses in complexity so quilters can hone their skills as they work their way through the book. Then, quilters will be inspired to use their blocks in a series of projects, both large and small. Created with intermediate quilters in mind, the book includes: Jackson's speedy chain-piecing technique for paper piecing; graded patterns to create the perfect finished block size; traditional and modern settings; watercolor illustrations of gemstones.
A concise, systematic, yet comprehensive ``textbook'' treatment of the science.

Highlights recent advances and important contributions; explores new methods of study and determination, crystal structures, causes of color, new gem minerals, new methods of gem synthesis, manufactured gems, chemical compounds used as substitutes, and imitations and simulations. Includes 12 full color plates, 350 halftones and line drawings, and a Gem Index that lists commonly sought characteristics along with page number references.
Samar Najm Abul Huda's translation of Ahmad ibn Yusuf al Tifaschi's study of gems. Born in 1184, Al Tifaschi first learned about gems from his father, and augmented his knowledge through readings of Aristotle, Theophrastus, and Pliny, as well as through extensive travels to mines and trading centers. In 1253, he wrote what later became known as the most 'methodical and complete' work on precious stones. Gemologists of today are still astounded by the advanced observations that Al Tifaschi made in this work.

The rapid growth of gemological sciences and mineralogy demands a dictionary such as this for gemologists, mineralogists, geologists, jewel dealers, industry and hobbyists. With some 16,000 comprehensive definitions, supplemented by more than 250 diagrams and figures, this is a one-stop reference to any matter dealing with gems and gemology.
From the dawn of time, ruby and sapphire have both attracted and fascinated humans in ways that few other items could.While objects of desire are found throughout the natural world, physical beauty is too often ephemeral. From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants. The exception is precious stones. Not only are they the most durable creations of mother nature, but their visual splendor is truly eternal.In this companion to his 2013 book, Ruby & Sapphire--A Collector's Guide, Richard Hughes examines these gems from the gemological standpoint, delving into these gems not just from the aesthetic, but also from the scientific point of view.The product of nearly 40 years of firsthand experience, it covers every aspect of the subject from A-Z. History, sources, prices, quality analysis, synthetics and treatments, everything is here. Ruby & Sapphire--A Gemologist's Guide represents the most comprehensive book ever written on a single precious stone. With over 1000 photos, maps and illustrations and 3500 references, it is nothing less than a tour-de-force of gemological scholarship.
Sinkankas is the prime authority on gemology (author of Gem Cutting, Gemstones of North America, Beryl, Emerald...) and an expert gem cutter. He is eminently competent to present the critical remarks upon the 7,458 books here given meticulous description, synopsis, and criticism. Sinkankas owned most of these titles (his library was sold to the Gemological Institute of America) and has continued to handle other copies in his bookselling capacity. A noble work that will stand unchallenged for decades. Running headings are absent. Annotation copyright by Book News, Inc., Portland, OR
