Semi-Precious Gems

I've put off doing this for years, after this post in 2010 and this post in 2011.  Here is a list of semi-precious gemstones, based more or less on the original DM's Guide with regards to value.  There are no tables for actual gem values (purposefully, as the jewellery and lapidary industry does not want you knowing how valuable or invaluable these are).
