Nature Emerald VS Lab Emerald:
emerald enaggement rings have defects and cracks, which are similar to rubies. Their defects are mostly in the shape of “cotton wool”, and sometimes some black mineral inclusions and other impurities can be seen; Lab created emeralds are mostly clean or have a few bubbles.Lab-made emeralds typically cost less than natural emeralds of similar color, but the difference in price is matched by the difference in appearance.
There are emerald stimulants or imitations that you will find in the marketplace, which include cubic zirconia, yttrium aluminum garnet, synthetic spinel, and assembled beryl triplets. While these pieces have a similar appearance to emeralds, they are different from the popular green gem in their optical and physical properties.
Many naturally occurring green gemstones may look like emeralds and are easily misidentified as emeralds accidentally or deliberately. As one of the world’s popular gemstones, some unscrupulous vendors are quick to associate the emerald name to other less popular gems just to drive consumer interest, like calling chrome sphene “Mexican emerald” or green fluorite “African emerald.”However, gemologists are experienced in catching these and can distinguish emeralds from other gemstones.
Lab created emeralds or lab grown emeralds differ in color and contain no inclusions. Some view this as preferable, as inclusions can be seen as flaws. Synthetic emeralds are identical to natural ones in chemical composition and similar in appearance, although color and saturation variations may be detected by the eye alone. Man-made emeralds lack the rarity and detail of natural emeralds, as well as, in many cases, the expected color and saturation. It is important to note the difference between terms: while lab created emeralds
are real emeralds, they are not considered to be authentic emeralds, as they are fabricated in a lab and did not occur in nature.
Some of the most valuable emeralds are Colombian emeralds and, more recently, Ethiopian emeralds. The most value hinges on color, with prices affected by nuances of saturation and hue. The most sought-after color is slightly bluish-green in a medium-dark tone with vivid saturation.
Clarity is important as well, and compared to any other gem, inclusions in emeralds are much more tolerated. Top-quality stones that haven’t been enhanced can bring up to 50% more in price compared to treated stones of the same color, size, and clarity. Common treatments greatly influence the price of emeralds. Most emeralds have been treated for clarity enhancement through the use of oil or resin fillers. The reason for this is because they are a Type III gemstones, which means they almost always come with heavy inclusions. Untreated emeralds are rare to find, more so big ones that are over a few carats.
Most of the emeralds, even those in auction houses are treated. The Rockefeller Emerald, with an almost perfectly transparent and no enhancements, is a famous exception. This exceptional 18 carat stone sold for about $5.5 million USD
Even for unpopular untreated emeralds that have no inclusions, they still command the top price. Eye-clean Emeralds are oftennot sporting the most vivid greens either, but there are a lot of exceptions.
And lastly, like many stones, the size greatly impacts the per-carat price of fine quality emerald. For example, a high-quality 3-carat Colombian emerald stone is up to six times more valuable than three 1-carat emerald stones of the same quality.
If you ever get caught in a jewelry conundrum, then remember these simple guidelines: For evening and special occasion, use your emerald and other colored stone jewelry, for casual wear and formal attire at the workplace, slip on some diamonds. Also, remember to keep your jewelry to its context. And, finally, if you are ever in doubt, diamond is a versatile option that would be a great last resort

The more the iron atoms, the bluish the tones.
