We see quite a few beautiful gem bead jewelry pieces, created by many jewellery designers - well-known to hobbyist. Most of these people are very creative artists in their design, but several of them know little, or nothing, concerning the materials they are working with, and this might lead to disasters. This series will try to help you know concerning the stones and materials you are using and their idiosyncrasies. Let's begin with the basics.
What is a "PRECIOUS" and a "SEMI-PRECIOUS" GEM? They are minerals and rocks that that people consider distinctive, stunning and of value. Actually, there's no specific description, however , a definition must incorporate: the unique ness and beauty of the stone. This includes the colours, shine, optical effects, shapes, physical effects, hardness, and rarity of the stone. In the past, "Precious Gem" referred only to: Diamonds, Rubies, Sapphires, and Emeralds (plus, Alexandrites and Pearls), but now the term includes most gems. In this "PC" world, "Semi-Precious Gem" has fallen out of use for the reason that it's demeaning, plus with the introduction of quite a few unknown (i. e. Tanzanite) and previously unused gems (i. e. the Colours of Sapphire) the separation no longer applies
What is a "MINERAL"? It's a naturally occurring inorganic solid constitute of the earth's crust. Most minerals have their own chemical formula, molecule, and crystal forms. Examples are: Diamond, Sapphires, Peridot, Quartz (includes; Agate, Chalcedony, Jasper, and Opal), Garnet, Tourmaline, etc.
What is a "ROCK"? A rock is a natural aggregate of different or identical minerals. When you gaze at a rock, you will often see some of the different aspects of it is make up. Examples: Unakite, Ruby in Zoisite, Lapiz Lazuli, Marble, Tiger Iron, Granite, Gneiss, etc.
What is an "IMITATION"? Anything made to resemble a natural or synthetic gem. They imitate the look, color, and effect of the original, but they do not have the same chemical of physical characteristics. Examples incorporate: Glass, Austrian Crystal (leaded glass), CZ, Enamel, Plastics, Dyed Howlite and Marble, "Paste", Chinese Glass gems (Strawberry Quartz, Pineapple Quartz, etc.) etc.
What is a "SYNTHETIC"? They are crystallized man made stuff whose chemical and physical properties are, for the most part, similar to their natural counterparts. Examples are: Synthetic Rubies, Sapphires, Alexandrites, CZ, Chatam Emeralds, Hematine, Quartz, etc.
What is a "MAN MADE" gem? These are stones that do not happen in nature. Examples: Gold stone (glass & copper). Or they are "Block materials", which are reconstituted, crushed natural materials that are mixed having a resin and formed into blocks for cutting. Examples integrate: Block Azurite/Malachite, Block Coral, Block Black Onyx, Block Turquoise, etc.
