The undisputed ruler in the fascinating world of gemstones. One of the most charming, fascinating and remarkable creations of nature. At StarRuby.in, learn everything about this splendid gemstone... Star Rubies are beautiful gemstones that display a six-ray star that seems to glide magically across the surface of the gem when the latter is moved. This six-ray star is caused due to an optical phenomena known as "Asterism". The term "Asterism" is derived from the Greek word "aster", which means star, so asterism is commonly referred to as "star" or "star-effect". In simple words, asterism is a star-shaped light effect across the surface of gems. Other popular gemstones that display asterism are Star Sapphire, Star Rose Quartz, Star Garnet, Star Diopside, Star Moonstone, Star Spinel and Star Opal. More about Star Rubies on the Star Ruby Info page. Check out famous star rubies... the Delong Star Ruby, the Rosser Reeves Ruby, the Midnight Star Ruby and the Star Bharany Ruby. Visit The Star Ruby Shop, to purchase loose star rubies, ruby cabochons, faceted rubies, star sapphires, and more. All Guaranteed Natural and Untreated. Star Rubies are a rare variety of the gemstone Ruby. These magnificent gems display a sharp six- rayed star which seems to glide magically across the surface of the gem when the latter is moved. This is caused due to an optical phenomenon known as "Asterism". The star is best visible when the star ruby is seen in a single light...

  • Phenomenal Gemstones Possess Striking Optical Effects, Making Them Truly a Sight for Sore Eyes
    THE PHENOMENAL PROPERTIES OF GEMS Phenomenal gemstones possess striking optical effects, making them truly a sight for sore eyes. Here is GIA’s guide to understanding what makes each phenomenon so uniquely brilliant. ASTERISM CROSSING BANDS OF REFLECTED LIGHT CREATE A SIX-RAYED STAR-LIKE APPEARANCE. ASTERISM OCCURS IN THE DOME OF A CABOCHON, AND CAN BE SEEN IN GEMS LIKE RUBIES AND SAPPHIRES. ADULARESCENCE THE SAME SCATTERING OF LIGHT THAT MAKES THE SKY BLUE CREATES A MILKY, BLUISH-WHITE GLOW, LIKE MOONLIGHT SHINING THROUGH A VEIL OF CLOUDS. MOONSTONE IS THE ONLY GEM THAT DISPLAYS IT. AVENTURESCENCE FOUND IN NATURAL GEMS LIKE SUNSTONE FELDSPAR AND AVENTURINE QUARTZ, IT DISPLAYS A GLITTERY EFFECT CAUSED BY LIGHT REFLECTING FROM SMALL, FLAT INCLUSIONS. CHATOYANCY OTHERWISE KNOWN AS THE “CAT’S EYE” EFFECT, BANDS OF LIGHT ARE CAUSED BY THE REFLECTION OF LIGHT FROM MANY PARALLEL, NEEDLE-LIKE INCLUSIONS INSIDE A CABOCHON. NOTABLE GEMS THAT DISPLAY CHATOYANCY INCLUDE CAT’S EYE TOURMALINE AND CAT’S EYE CHRYSOBERYL. IRIDESCENCE ALSO SEEN IN SOAP BUBBLES AND OIL SLICKS, IT’S A RAINBOW EFFECT THAT IS CREATED WHEN LIGHT IS BROKEN UP INTO DIFFERENT COLORS. LOOK FOR IT IN FIRE AGATE AND OPAL AMMONITE (KNOWN BY THE TRADE AS AMMOLITE). LABR ADORESCENCE A BROAD FLASH OF COLOR THAT APPEARS IN LABRADORITE FELDSPAR, IT’S CAUSED BY LIGHT INTERACTING WITH THIN LAYERS IN THE STONE, AND DISAPPEARS WHEN THE GEM IS MOVED. INSIDER’S TIP: THE MOST COMMON PHENOMENAL COLOR IN LABRADORITE IS BLUE. PLAY OF COLOR THE FLASHING RAINBOW-LIKE COLORS IN OPAL THAT FLASH AT YOU AS YOU TURN THE STONE OR MOVE AROUND IT.

  • Star Stones (Asterism)
    Learning Series: Basic Rockhound Knowledge Star Stones (Asterism) When parallel, needle-like inclusions, or tube-like channels, are oriented along two or more of the crystal faces of a mineral, and when that stone is cut as a domed cabochon, a four- to six-rayed figure is displayed on the dome. This phenomenon of reflected light is called "asterism" and the gems are called star stones. The most commonly seen examples are star corundums; where there are inclusions of titanium oxide (rutile or "silk") parallel to three crystal faces giving a six-rayed star. In rare cases, a twinned crystal slightly offset with its own set of rutile needles can lead to the formation of a twelve-rayed star. Although rutile is an extremely common inclusion in sapphire, few good, natural, star sapphires are found. One of the major reasons is that the heating, which is almost universally done to sapphire rough, dissolves rutile needles; clarifying and sometimes color enhancing the stone, yes, but eliminating potential stars! [Rutile needles (silk) aligned in three directions in unheated corundum] [Star ruby, white star sapphire ring, rare bi-colored star sapphire] The only other gem which commonly forms stars is quartz, where the phenomenon tends to be more visible in transmitted than in reflected light. In this species, rose quartz is the most frequently asterated variety. Most citrine in commerce has been heated, which tends to dissolve the fine rutile inclusions necessary for star formation, so it is rather rare. In fine, near-transparent quartzes which have been cut to a spherical shape, multiple stars can form an intersecting pattern over the surface.

  • Mining, Geology, and Geological History of Garnet at the Barton Garnet Mine, Gore Mountain, New York William Kelly
    6: RARE EARTH ELEMENT AND YTTRIUM MINERAL OCCURENCES IN THE ADIRONDACK MOUNTAINS 7 MINING, GEOLOGY, AND GEOLOGICAL HISTORY OF GARNET AT THE BARTON GARNET MINE, GORE MOUNTAIN, NEW YORK WILLIAM KELLY New York State Geologist, Emeritus, Division of Research and Collections, New York State Museum, Albany, NY 12230, [email protected] KEYWORDS: Garnet, Mining, Gore Mountain, Metamorphism, Lyon Mountain Granite ABSTRACT Garnet megacrysts commonly 30 centimters (cm) ranging up to 1 meter (m) in diameter occur at the summit of Gore Mountain, Adirondacks, NY and were mined there for abrasives for more than a century. The mine, owned by Barton Mines Co., LLC, is roughly 2 km x 150 m and is located in a hornblende-rich garnet amphibolite at the southern boundary of a metamorphosed olivine gabbro body that is in fault contact with charnockite. Barton supplies garnet, a chemically homogeneous pyrope-almandine, to the waterjet cutting, lapping, and abrasive coatings industries. The garnet megacrysts are reliably dated at 1049 ± 5 Ma. The growth of the garnet megacrysts was facilitated by an influx of hydrothermal fluid emanating from the ore body’s southern boundary fault. The fluids were most probably associated with the intrusion of the Lyon Mountain Granite (1049.9 ± 10 Ma) and/or associated pegmatitic rocks late in the tectonic history of the Adirondacks. INTRODUCTION The Adirondack Mountains in upstate New York are a small outlier of a larger body of rocks of similar age and geologic history that is located to the north in Canada. The Adirondack region can be loosely divided into amphibolite metamorphic facies Lowlands, in the northwest, and the granulite facies Central Highlands, which are 86 THE ADIRONDACK JOURNAL OF ENVIRONMENTAL STUDIES VOLUME 21 87 7: MINING, GEOLOGY, AND GEOLOGICAL HISTORY OF GARNET AT THE BARTON GARNET MINE, GORE MOUNTAIN, NEW YORK separated by a very large, northwest-dipping fault zone.

Second edition Physical Properties of Minerals • Physical properties of minerals are controlled by chemical composition and structure • So, samples of same minerals exhibit the same properties • Thus physical properties can be used to identify minerals • Physical properties can be grouped into four categories Introduction to Mineralogy, William D. Nesse Copyright © 2012, by Oxford University Press, Inc. Second edition Properties based on 1.Mass (density and specific gravity) 2.Mechanical cohesion (hardness, tenacity, cleavage, fracture and parting) 3.Interaction with light (luster, color, streak, lumnescence) 4.Other Properties (magnetism, electrical etc) Introduction to Mineralogy, William D. Nesse Copyright © 2012, by Oxford University Press, Inc. Second edition Density • Density() : mass (m) per unit volume (v) = m/v (g/cm3) • Specific Gravity (G) = density of a material divided by the density of water at 4C G = /H2O is unit less because G is the ratio of two densities. – Since the density of water is 1 g/cm3, the numerical value of density and specific gravity are same in metric system Introduction to Mineralogy, William D. Nesse Copyright © 2012, by Oxford University Press, Inc. Second edition Specific Gravity • Specific Gravity depends on the chemical composition and how tightly the atoms are packed • Packing Index how tightly the ions are packed in a mineral: PI = (VI/Vc ) * 100 Where Vc is the unit cell volume and VI is the actual volume of the ions based on their ionic radii • Maximum packing index for a close packed structure of uniform spheres is 74% -- most minerals have values between 35 and 74 • Minerals formed at high pressure has higher PI : – Kyanite PI = 60.1 and G = 3.6 Andalusite PI= 52.3 and G = 3.1 • G depends on the composition also.

Nesseu, Bell TelephoneLaboratories, Inc. Murray HilI, Neu Jersey. INtnooucuoN It has beengenerally accepted that asterismin corundum (star rubies and sapphires)is causedby needlesor rutile (TiOz) aligned along crystal- lographic planes of the corundum (e.g. Webster, 1962). The evidence given ty Tait (1955) was: (1) the presenceof titanium, (2) the needle- like habit, and (3) the squarecross-section of the needles.Based on the analogy with rutilated quartz, and by eliminating octahedrite and brook- ite by the morphology, rutile was accordingly identified. This type of evidence,however, is explained equally well by either TiOr or the com- pound aluminum titanate Al2TiO6. ConuNrulr Gnowrn CousrrBnetroNs The technique for the laboratory growth of star rubies and sapphire has beenrevealed in patents by the Linde Division of the Union Carbide Corp. (Burdick et aI., 1949, 1954). Corundum is grown by the Verneuil technique with the addition of, preferably, 0.1 to 0.3 percent titanium oxide in the feed powder.

  • Ruby – the July Birthstone
    Learning Series: Birthstones – July Ruby – The July Birthstone Background The story of the July birthstone traces to the ancient Silk Road of China. Notes about the transport of rubies can be found all the way back to 200 BC, as Asian traders imported rubies into to their native cultures where they were held in very high regard for their gem quality and red color; a good luck color in many Asian cultures. Rubies were used not just for jewelry, but to ornament armor, scabbards and harnesses for wealthy noblemen. Some wealthy people even laid rubies into the foundations of their homes as a good luck charm. The word “ruby” comes from the Latin "ruber," meaning red. It is a variety of the mineral Corundum and for a ruby to be born in the natural environment, a perfect combination of aluminum oxide, correct temperature, correct pressure in the earth’s crust and very low silicon content is a requisite. This makes rubies very rare and large rubies (over 2 carats) even rarer. Host rocks of rubies often include metamorphic dolomite marbles, gneiss, and amphibolite. However, rubies are not normally extracted from the primary deposits due to the high cost of mining. They are retrieved from the secondary deposits which are usually alluvial. Mining of rubies is still fairly primitive and takes many man-hours of labor to find the stones. Once the gem bearing alluvial material is identified, then the gravel is sifted through wire screens and picked out by hand. Rubies were once known in eastern legends as “blood drops from the heart of the Mother Earth”.
