This has been discussed before...
Quoting Index from the first novel:
Quote:
"Magic isn't something that... espers, 'those with talent', can use... Because 'those without talent' wanted to be able to do the same things as 'those with talent', they gave birth to a ceremony and practice called... magic."
"You don't understand? 'Those with talent' and 'those without talent'... run on different circuits... 'Those with talent' cannot use magic designed for 'those without talent'..."

So Gemstones shouldn't be able to use magic either without going haywire.
