The use of beads and gemstones in jewelry dates all the way back to ancient times. The precious beads were made from shells, seeds, animal bones, ivory and other natural materials. In fact the word 'bead' itself comes from a middle English word meaning "berry." Early cultures used them as tokens to trade for goods and services therefore they have always held value.
Quality gemstone beads are hard to come by these days. In fact, most jewelry stores just carry inferior quality imitations that will fade quickly and look beat up after a few wearings. It is very difficult for those who have been shopping at department stores or discount jewelry chains to find high-quality gemstones and beads on their own. These companies only want to sell you the cheapest stuff they can get away with so they can make a bigger profit.
What are Metaphysical Properties?
Metaphysical properties can be used to describe the positive traits of a brand and how it relates to its audience. Metaphysical properties are meant to add on to the meaning behind a brand or product, and can be used in order to connect with your target audience more effectively.
Metaphysical properties are the spiritual or symbolic meaning behind each stone. These properties are determined by various beliefs, cultures, and religions around the world. While not all of these meanings are used in astrology today, many still hold significance to those that do practice this ancient art.
What Are Physical & Chemical Properties Of Gemstones?
The properties of gemstone beads are classified under two categories: physical and optical. Physical properties are concerned with what a bead is made of and how it is made, whereas the optical classification deals with how a gem interacts with light.
The physical properties of a gemstone do not react to light falling on it. In fact, each property of a gemstone, optical or otherwise, depends on the material it is made of and the arrangement of atoms in its structure. That is why amber beads look very different from shiny obsidian pendants, although they are both gemstones.
Chemical compositions and three dimensional structures distinguish one gemstone from another. Crystalline gems have a regular, repeating structure of atoms, while amorphous gems contain irregular patterns. On a structure basis, gemstone beads can be divided into two groups – crystalline and amorphous.
Physical and Chemical Properties of Various Gemstone Beads
Agate: Agate is a type of chalcedony that forms in concentric layers. These layers are usually bands of microscopic quartz crystals. Some agate also contains cryptocrystalline quartz, or minute crystals that are only visible under high magnification. Although agate is commonly found in shades of brown and red, the color comes from impurities such as iron and manganese rather than from organic sources.
The most valued agates are both colorful and translucent. This makes them popular for use in jewelry, specifically necklaces and bracelets. The chemical formula of agate is SiO2, its specific gravity is 2.61, and its refractive index is 1.53 - 1.54.
Amethyst: Amethyst gemstones are one of the most popular and well known gemstones. Amethyst is a variety of quartz and is colored by natural irradiation, which causes the purple color in these stones. This article will explore the physical and chemical properties of amethyst gemstones to better understand how they were formed and why they look like they do.
The hardness level of an amethyst stone ranges between 7.0-7.5 on the MOHS scale, making it fairly durable compared to other types of gems such as diamonds (10 on MOHS). Its chemical formula is SiO2 and refractive index is 1.54 - 1.55.
Hematite: Hematite, also known as bloodstone, is an iron ore mineral with a chemical composition of Fe2O3. It has properties similar to magnetite and is magnetic. The name hematite comes from the Greek word for blood because of the red color of some forms of hematite. Hematite is one of several iron oxides that are collectively referred to as "iron ores".
The chemical formula of hematite is Fe2O3, the hardness of this gemstone is 6.50 on MOHS scale, its specific gravity is 5.20, and the refractive index is 2.94 - 3.22.
Citrine: The citrine gemstone is one of the most popular yellow gems. This semi-precious stone has a beautiful golden color that can be used to create stunning pieces of jewelry. Citrine is commonly mistaken for the amethyst gemstone. It was named after the French word “citron”, which means lemon or lime in English. The name was given due to the resemblance of this semi-precious stone with these fruits.
The hardness of citrine gemstones is SiO2, specific gravity is 2.6 - 2.7, hardness is 7 on MOHS scale, and refractive index is 1.57 - 1.58.
Jade: Jade is an ornamental stone that has been appreciated for thousands of years. Although it is hard, its toughness makes it resistant to breakage. Here are some physical and chemical properties of Jade gemstones which you may be interested in:
Physical Properties: Hardness (Mohs): 6; Density (g/cm3): 3.5; Specific gravity: 2.61; Melting point (°C): 1750; Boiling point (°C): N/A; Refractive index: 1.66 - 1.68.
Moonstone: The moonstone is a variety of feldspar which exhibits a pearly luster or sheen. It is translucent and varies in color from pale yellow to gray, brownish-yellow, greenish-gray, reddish brown and rarely almost colorless. The name derives from the fact that its light appears as a reflection of the moon. Moonstone gemstones are found worldwide but most often in India where they were first discovered and mined by Hindu traders more than 2,000 years ago.
The chemical formula of moonstone is KAlSi3O8, the hardness is 6 on MOHS scale, specific gravity is 2.57, and its refractive index is 1.52 - 1.53.
