Collecting 1 of each kind of gemstone cut is a great place to start your collection. Once you have 1 of each, you can work on buying better and better quality gems to replace the various cuts in your collection.

People also collect all the cuts, except they will only collect one type of gem, color, and/or from one origin such as Burma or Madagascar Rubies. When it comes to collecting gems the only limitation is your imagination and your personal preference for certain gems.

Clarity Scale

This is the clarity scale used on all of our Gemstone Auctions


IF Clarity – Loupe clean – internally flawless, free of inclusions.

VVS Clarity – Almost loupe clean – very, very slight inclusions; inclusions are barely seen under 10x magnification.

VS Clarity – Usually Eye clean – very slight inclusions; slight inclusions will be visible by the trained eye, or when viewed under 10x magnification.

SI Clarity – Slightly included – Inclusions are noticeable and can be seen with the naked eye.

I1 ClarityIncluded – inclusions are obvious and can be seen with the naked eye.

Transparent – A gemstone having the property of transmitting light without serious diffusion / may have rutile or other inclusions.

Translucent – Allowing light to pass through, but not transparent.

Opaque – Does not allow light to pass through.


Type 2 gemstones include amethyst, ametrine, andalusite, alexandrite, citrine, corundum (all sapphire and ruby), garnet, iolite, peridot, spinel, and others. These stones are usually included, which means that some eye-clean stones can be found, but in lesser amounts than type 1 stones.  Type II gemstones with minor inclusions visible to the unaided eye are very often used for jewelry; these include sapphire and ruby.

Type 3 gemstones include gems such as green emerald, red beryl (bixbite), and varieties of tourmaline. For a type 3 gemstone, an IF clarity rating is incredibly rare, since these stones are almost always included. For type III gemstones, even those with very noticeable inclusions are often used for jewelry, such as the case with emerald and watermelon tourmaline.
