Olivine has also been called "peridot" which ranges in color from a yellowish green to pure green to a nearly olive green color.
The finest peridot, the Egyptian material, has a minimum of yellow in it and is a bright clear green. Unfortunately the Egyptian material is no longer mined and not readily available on the market.
You can find fine Burmese peridot, which is fairly rare, in sizes over ten carats, with a fairly dark clear green color with only a hint of yellow.
Norwegian peridot is yellowish green but it is much softer in color than the other sources.
Arizona material is readily available in sizes under five carats and is characteristically a bright yellowish green. It is mined on a Reservation by the San Carlos Indians.
Peridot is a fragile stone; it is brittle and will abrade easily around facet junctions. It should be set into protective mounting. Never put peridot in an ultrasonic cleaner: it may not break but the internal fracture may be massive.
Peridot over ten carats with a bright medium green color with a minimum of yellow and good transparency with no sleepiness or visible inclusions will command the highest price per carat. Fine stones will fall into a moderate price per carat category. Large peridot even of lesser quality will usually be in the lower end of the moderate per carat price range due to its rarity. Peridot under two carats will usually fall into the low price per carat category even for fine qualities. Fine quality stones in two to five carat sizes may be in the moderate price range but olive colored material or heavily included stones will fall into the low price per carat group.
