The gemological name of peridot is olivine. This beautiful stone is always green, but can also contain many gemstones or other minerals. This can be biotite, silicon glass, pyro-garnet, mica, and spinel. It is very green and transparent, so any inclusions are easier to see. 

Peridot jewelry is in great demand because of its green color. It is available in various shades of green, from light green to stunning apple green. The color comes from the iron in the crystal formation, not from impurities, as in many gemstones. You can look for green gemstones at to wear a piece of great artistic jewelry.

Due to the variation in green color, it is confused with other gemstones. These include green apatite, green zircon, green tourmaline, and green sapphire. More intense colors are not as common as lighter stones, so they are the most expensive in the Peridot gemstone range.

Peridot has the same hardness as feldspar or quartz and has a value of 6.5-7 on the Mohs hardness scale. Rarely, peridot can have a cat's or stellar eye effect, but above all, it is a beautiful clean stone. Peridot looks amazing in silver or gold. It's also a great stone to match with other colors. 

Color is personal, but most people like to combine peridot with precious stones like tourmaline, spinel, diamonds, or other precious and semi-precious stones. If a woman has green or brown eyes, a peridot necklace will bring out her eye color with a striking effect.

Sometimes peridot is treated differently. It can be crushed to improve surface appearance or treated with polymer fillers to reduce imperfections. In the world of gemology and jewelry making, it is very common to treat gemstones with heat or radiation, as well as with grease and stuffing.
