Following the reference link on the Wikipedia page, I found this:

jade (n.1) Look up jade at Dictionary.com ornamental stone, 1721, earlier iada (1590s), from French le jade, misdivision of earlier l'ejade, from Spanish piedra de (la) ijada or yjada (1560s), "(stone of) colic or pain in the side" (jade was thought to cure this), from Vulgar Latin *iliata, from Latin ileus "severe colic" (see ileus). As an adjective from 1865.

So apparently the ilia in jadeite is because of colic and jade's supposed healing powers, colic being one of the things it healed.
