Count of gem colors (Burning Crusade Classic)
 

I'm trying to revive (or find) an addon that counts the number of each color gem in equipped items.

Documentation on the API for finding gem information is hard to find. Can anyone point me in the right direction?

If you're wanting to count socket colors, this'll require a ton of server requests using socket query calls. Alternatively, if you want the gems themselves, you could parse the gem fields of the ItemLink. Note, the ItemLink format may differ between retail and classic as many fields don't apply to both versions. Keep this in mind when reading API documentation and be sure to double-check with your own testing.
