Introduction

What is an Emerald?

Emerald is a variety of the mineral beryl. It comes in a range of colors, but green is the most popular. The color of an emerald is caused by trace amounts of chromium and vanadium in its crystal structure. Emeralds are hard enough to be used as gemstones, but they aren’t as hard as diamonds or sapphires. Because emeralds contain small amounts of iron oxide, they tend to be more transparent than other green gems such as aquamarine or peridot; however their transparency can vary depending on how deep they are mined from the earth’s crust–the deeper they’re buried under layers upon layers of rock material like shale or sandstone (which contain less iron), the clearer your stone will look when cut into facets for faceting purposes. Emerald is a variety of the mineral beryl (Be3Al2Si6O18), colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the MOHS scale and a density of 2.71–2.77 g/cm3. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor (HS).  

Emerald is a precious gemstone. It has a rich history and is known for its healing powers. Emerald gemstones can be used to make accessories, rings and pendants. They have many benefits and have been used mostly as jewelry pieces by people throughout history

How to Test an Emerald?

You can test an emerald by using a loupe. Look at the color, transparency and clarity of the stone. You want to see a bright green color with no brown or gray inclusions. Next look at how well cut it is; make sure there are no chips or cracks on its surface. If your emerald has been polished properly, you should be able to see some light reflect off of its surface when you hold it up against light coming from behind you (this is called “luster”).

What is the Luster of Natural Emeralds?

Emerald is a transparent gemstone, and it’s considered to be one of the most beautiful stones in the world. The color of an emerald can range from light to dark green, with shades that vary from yellowish to bluish-green. Emeralds are usually cut en cabochon (with flat backs), but they can also be faceted or polished on all sides. Emerald is actually beryl–a mineral made up of aluminum silicate–but its natural green color makes it distinct from its other varieties in this family: aquamarine (blue), heliodor (yellowish-green), morganite (pink) and red beryl (red). The luster of natural emeralds depends on their transparency and color; some have oily reflections while others have glassy ones; some appear greasy while others look earthy or dull when viewed at certain angles under direct light source

How Do I Clean My Natural Emeralds?

Emeralds are one of the most beautiful gemstones on Earth, but they can also be difficult to clean. The best way to clean your natural emeralds is with tumbled stones, a soft brush and warm water. Do not use a strong solvent or chemical cleaner on your emeralds as it could damage them!

The best way to clean your precious gems is to use tumbled stones.

The best way to clean your precious gems is to use tumbled stones. Tumbled stones are made from natural materials like rock salt and silica, which are safe for most gemstones.

They’re inexpensive, easy to use and can be purchased at many jewelry stores or online retailers.

To clean your gemstone using a tumbled stone:

• Place the gem in an open tray with enough room for it not to roll around on its own (you don’t want it getting lost in the bottom of your drawer!)
• Pour some water into another dish nearby–not directly on top of your gemstone–and dip one end of each tumbled stone into this wetting solution before rubbing them gently across each side of your diamond or other precious stone until they’re shiny again!

Is There Any Difference in the Quality of an Emerald?

Emeralds differ in quality based on the color, clarity, and cut. The best quality emeralds have a uniform color and no inclusions. These stones are also cut to maximize their brilliance.
