== Example ==
 local itemLink = "|cff0070dd|Hitem:27773:3010:2729:2729:2739:0:0:0|h[Barbaric Legstraps]|h|r"
 local gem1name, gem1Link = GetItemGem(itemLink, 1)
 local gem2name, gem2Link = GetItemGem(itemLink, 2)
 local gem3name, gem3Link = GetItemGem(itemLink, 3)
 if gem1name then
   DEFAULT_CHAT_FRAME:AddMessage("Gem 1: "..gem1name..", Link: "..gem1Link)
 end

 end
 if gem3name then
   DEFAULT_CHAT_FRAME:AddMessage("Gem 3: "..gem3name..", Link: "..gem3Link)
 end

====Result====
: As long as {{loot|rare|Barbaric Legstraps}}, {{loot|rare|Bright Living Ruby}}, and {{loot|rare|Shifting Nightseye}} all exist in your local cache, you will see the following lines in your chat frame:
: Gem 1: Bright Living Ruby, Link: {{loot|rare|Bright Living Ruby}}
: Gem 2: Bright Living Ruby, Link: {{loot|rare|Bright Living Ruby}}
: Gem 3: Shifting Nightseye, Link: {{loot|rare|Shifting Nightseye}}

==Details==
: This function will '''ONLY''' retrieve data that is in your local cache.
: If you have never seen the item that belongs to the Item ID or Item Link it will return ''nil''.
: Using the name may be ambiguous if you have more than one of the named item.

== Common usage ==

local gemName, gemLink = GetItemGem(itemLink, index)
