Testing Hardness of a Mineral Testing Hardness of a Mineral The hardenss of a mineral is one of the most diagnostic and easy tests to perform in the attempt to indentify an unknown mineral. Hardenss is a measure of a mineral's resistance to abrasion and reflects the atomic structure of a mineral. Mohs Hardness Scale Hardness is measured on the Mohs Scale , identified numerically hardness of by standard minerals, from 1 (softest) to 10 (hardest): Talc Gypsum Clacite Fluorite Apatite Orthoclase Quartz Topaz Corundum Diamond A mineral of a given hardenss will scratch a mineral of a lower number. With a systematic approach, you can use minerals of known hardness to determine the relative hardness of any other mineral. Click here to continue Read More Go to Site

Votes:0 THE MINERAL DIAMOND Chemistry: C, Elemental Carbon Class: Native Elements Subclass: Non-metallics Group: Carbon Uses: usually as a gemstone and abrasive, also scientific uses. For natural diamond mineral specimens, see our diamond specimens page. For Diamond Jewelry, see Diamond is the ultimate gemstone, having few weaknesses and many strengths. It is well known that Diamond is the hardest substance found in nature, but few people realize that Diamond is four times harder than the next hardest natural mineral, corundum (sapphire and ruby). But even as hard as it is, it is not impervious. Diamond has four directions of cleavage, meaning that if it receives a sharp blow in one of these directions it will cleave, or split. A skilled diamond setter and/or jeweler will prevent any of these dire Read More Go to Site
Votes:0 About Smithsonian | Websites A-Z Home › Encyclopedia Smithsonian › Science and Technology Hope Diamond The history of the stone which was eventually named the Hope diamond began when the French merchant traveller, Jean Baptiste Tavernier, purchased a 112 3/16-carat diamond. This diamond, which was most likely from the Kollur mine in Golconda, India, was somewhat triangular in shape and crudely cut. Its color was described by Tavernier as a "beautiful violet." Tavernier sold the diamond to King Louis XIV of France in 1668 with 14 other large diamonds and several smaller ones. In 1673 the stone was recut by Sieur Pitau, the court jeweler, resulting in a 67 1/8-carat stone. In the royal inventories, its color was described as an intense steely-blue and the stone became k Read More Go to Site

Votes:0 IRON-NICKEL Chemistry: Fe-Ni, Elemental Iron-nickel Class: Elements Group: Iron Uses: as a mineral specimen and scientific studies. Specimens Native Iron is quite often a misnomer as natural iron is not necessarily "native" to Earth since it rarely occurs on the Earth's surface by terrestrial processes. It is mostly found in the form of meteorites that have impacted the Earth's surface. A few rare terrestrial gabbros and sulfide deposits do contain elemental iron-nickel deposits, these are the only truly native iron-nickel. All natural iron, whether it is native or meteoritic, is actually an alloy of iron and nickel. The two elements are combined in varying percentages from less than 6% nickel to as much as 75% nickel, although iron is by far more common than nickel. The meteorites that co Read More Go to Site

Votes:0 Resources ORGANIZING A MINERAL COLLECTION Advertise on this page This page mentions mineral collecting, mineral storage, labeling, and proper care for minerals. Collection Methods Many collectors save any mineral type they find. They try to have as many minerals in their collection as they can. Since there are over 3,000 minerals, and each one has variances, they will never reach the goal of having every mineral. No collection in the world is close to complete. A collection method known as specialized collecting is used by many collectors throughout the world. Instead of collecting any and every mineral specimen, specialized collectors collect only certain types of minerals, based on several classification "groups". These groups compromise minerals that have some similar characte Read More Go to Site

Votes:0 NATIVE SILVER Chemistry: Ag, Elemental silver Class: Elements Group: Gold Uses: Minor ore of silver for use in jewelry , coins and photographic films and other industrial uses. Specimens Silver has been mined for eons and has always been popular in jewelry and for coinage. Only in the past hundred years however, has the demand for silver been so great. The reason for this demand is the use of silver in the photography industry, which takes advantage of silver's reactivity to light. Native Silver is rare and much silver is produced from silver-bearing minerals such as prousite, pyrargyrite, galena, etc. Specimens of Native Silver usually consist of wires that are curved and intertwined together, making an inspiring mineralogical curiosity.
