I think it's because gems and crystals take hudreds of years to form, so for a gem to be in labor for a thousand something years, wouldn't exactly be neccessary. So, they give their child their gem. OR Steven was dying and rose decided to give him her magic so he would be able to heal somewhat like a gem would.
