The best way is to take it to a lapidary or to a certified gemologist.
The quick and dirty way:
1. The stone must be a shade of green; if dark green (supposedly rarer), it means the stone has more iron in it.
2. Upon an inspection with a magnifying glass or something more powerful, you should be able to find inclusions. If it is totally clean (meaning no inclusions), then most likely it is a colored CZ (cubic zircon), aka, lab-made stone.
3. Some experts expect it to show a rainbow of colors when held against a source of light (natural and artificial). Most natural stones are expected to behave this way.

The most expensive form of peridot comes from specific meteorites, or, as they are known to collectors, pallasites. Peridot found in these is usually not in great shape due to impact, but when they are workable for faceting can run thousands of dollars above earthly peridot. A peridot from a pallasite found by Robert Haag is listed at $50,000. Part of that is likely the setting which is 22 karat gold, rimmed with diamond and lesser stones culled from the main peridot. On the same site for Robert Haag there is a 1.5 carat faceted peridot pulled from a pallasite. Price for that is not listed however.
You can try and fake it, but you will be eventually caught since the doctor will scan you for the stones.
Price is determined on the basis of colour, clarity, carat weight and location
They sell jewelry that have created stones and have gold plate. They are required to tell you what is artificial and fine jewelry.
There are many online shopping sites that sell crosses with peridot. Sears, who has an online presence, has a beautiful selection of sterling silver crosses decorated with peridot gem stones. The cross pendants range in price from about $20 to $300.
Peridot is typically found in small to medium sizes, with most gem-quality stones ranging from 1 to 10 carats. Larger sizes can be rare and more valuable. It's important to note that peridot can also be found in smaller sizes for jewelry like earrings and pendants.
Fake stones can be removed from jewelry by carefully inspecting the piece to identify the fake stones, and then using tools like tweezers or a small pick to gently pry them out. Be sure to handle the jewelry with care to avoid damaging any surrounding genuine stones or the setting. If you are unsure about removing the fake stones yourself, it's best to consult a professional jeweler for assistance.
The value of peridot birthstones can vary significantly based on factors such as size, quality, and origin. Generally, peridot is relatively affordable compared to other gemstones, with prices typically ranging from $50 to $400 per carat. Higher-quality stones with exceptional color and clarity can command prices upwards of $1,000 per carat. Ultimately, the worth of a peridot is influenced by its specific characteristics and market demand.
Depends on size, clarity, color. There would be a healthy markup if the origin was proven. Compare "palladot", the gem peridot found in pallasite meteorites; cut stones of this material go for far more than terrestrial peridot.
It's fake!
Fake cyrstals. (I think!)
