A crystal sun represents the intended idealology of perfection, and it is only seen as brighter because a person is already accustomed to having 'crystal' eyes that are only used to seeing in a certain way. It is a little sad, that the gold sun cannot be appreciated in the same way due to an unwillingness to see it as beautiful. Not to mention, gold is softer warmer and melleable while crystal has sharp edges and hard places, cold like ice.
