GIA Collection 33479

Among the collection assembled by Dr Edward Gübelin are a number of uncommon gemstones from many worldwide localities. Documents, like the ones below, present information on gemstones that range from occasional use in jewellery to those that are quite rare and seldom faceted because of the lack of suitable starting material.
