Although none of us will ever see a treasure chest full of emeralds, rubies and sapphires out a pirated movies, which will have most of us, jewelry with precious stones. And 'traditional, but more importantly, are beautiful gems. When worn properly, are a statement about the fashion sense of security and financial institution. Since their value remains relatively stable, gems are a great way to share memories and prosperity of future generations.
There is no scientific definition for the gem and jewelry;These are marketing concepts. Minerals by geological processes occur continuously in the deep Earth formed. If people dig certain minerals and cut some forms, are gems. When placed in a decorative frame for display, were recorded.
While these natural processes to create an amazing variety of beautiful gems, some jewelry grown in their natural state. Jewelers cut and polish stones and make other improvements to theirAnd the resolution or stabilization of their chemical composition, so that more high quality jewelry available to the public. As much as 80 percent of all gems are treated in some way before reaching the retailer.
Gem Quality
Like diamonds, classified and rated by the "Four Cs":
Color:
The most important factor in the evaluation of precious stones, gems, with the most brilliant, bright colors usually command a higher price. Particular gems are only certain colorsenough of their chemistry. However, when assessing the color, the judge carefully call it: a pale green peridot Not only because it is not the same green as an emerald. Sapphires and rubies are the same mineral corundum, rubies are red corundum, all other colors are called sapphires.
Carat:
Heavier stones are rare, more expensive than smaller ones. Rarity of large stones, also depends – the world's largest cut 23ct Ruby is a little higher, while the largest topaz isct nearly 23,000! Carat measures the weight of the stone, but the crystal, affecting the structural and chemical properties of different density, which means two stones of the same size have a different weight may vary slightly. For this reason, colored stones are often listed according to size. (By the way, "ct" measures based on weight, "ct" measure the purity of gold, a "cursor" is a set of characters and a "carrot" is a vegetable.)
Denomination:
Determine the final beauty of the stone through corners and precise collectionProportions. Diamond focuses on maximizing the brilliance (reflected light), while the art of gemstone cutting is to maximize the color. There are many traditional cuts – Cabochon, emerald, heart, marquise, oval, pear, princess, round brilliant, able to cut the space – and a difference in quality between a good stone and a beautiful stone.
Clarity:
Defects (called "inclusions") are present in all natural stone – part of the proof of natural origin. Fewer errors: a precious stone.Inclusions can also help determine if a gem has been treated. As with other factors, is clarity on closely related species – a flawless Emerald would be too expensive, flawless aquamarines are relatively common. "Looks Flawless" is a goldsmith trained not to examine a stone inclusions under 10x magnification.
Hard stones and semi-artificial
Semi-precious
Diamonds, emeralds, rubies and sapphires have always been the most popular gemstones, so some jewelers took another callGemstones "semi-precious stones. It 'was a mistake and is a misleading term, these pieces are not" semi-precious. "Indeed, a prime number, or Amethyst Agate much more expensive than medium-grade rubies, emeralds or sapphires.
Not even "all that glitters is gold," wrote JRR Tolkien, and not everything that shines a gem. Imitations of varying quality and costs are available and consumers should not for what they are not always pay. According to the law can not be sold without these unique identificationthat is not natural. The FTC defines two types of non-natural gemstones:
Lab-created:
"Lab has created … the same chemical, physical and optical properties of natural ruby, emerald and diamond, etc." Minerals have a specific composition that can be reproduced, lab-created gems to be real jewels in every sense.
Slacker:
"Simulation (or imitation) merely resembles the natural stone." Simulants are not the same type of rock, despite their appearance.
ForFor example, a diamond of pure carbon. A lab-created diamond is pure carbon and hard as a diamond, because it is a diamond. A Cubic Zirconia (or CZ) is zirconium oxide. Quality CZs look like diamonds that only an experienced jeweler can tell the difference (in stone, that is, everyone can tell a diamond from a CZ by the price tag). Most natural stones have inclusions, and created in the laboratory and simulant gemstones have few or none. These treasures are more affordable than fakeNatural stones, which look real and are perfectly acceptable to wear any piece of jewelry at any time.
Gemstone Symbolism
old mythologies of a pair of magic gems, take the stones was associated with a birth of a way to ensure happiness and Stones remain popular gifts. Must not be exceeded by the mythologist, it came with an anniversary gemstone gem sellers list. Maybe they thought that they were not apologize enough to buy this gem jewelssomeone special. And while it was probably not think of jewelry, most of the United States have designated gems state language. If your wife was born in Utah, consider a topaz ring for them. If the husband is a native New Yorker, a set of twins grenade house could remember.
Regardless of when and why gemstone jewelry, get what you pay to know what you are looking.
