Peridot belongs to the forsterite-fayalite mineral series which is part of the olivine group. It is one of the "idiochromatic" gems, meaning its color comes from the basic chemical composition of the mineral itself, not from minor impurities, and therefore will only be found in shades of green. In fact peridot is one of the few gemstones found in only one color. Historically important sources in Egypt have been superseded by today's main sources in Arizona and Pakistan. The Pakistani peridot in particular is very fine, and a new find in Pakistan in the mid-1990's has made peridot available to a wider market. The supply of peridot from China is also increasing and we have recently sourced top quality peridot from Vietnam.
They say buy by size and give you measurements we don't use in the US. They say sizes comparable to American coins but don't say which coins equal what size they are giving............. You just have to go by size of instrument ...
