OK I am not sure on this but i'll take a shot. You are correct sugar crystals are clear. However their surface is imperfect and does diffuse some light. Rock candy having only a single surface only diffuses a portion of light and the rest continues through. Sugar having thousands of tiny surfaces diffuses nearly all the light. An easy way to test this would be to take a clear rock candy and crush it up. If you can see through the powder then i am wrong. I think you'll find though that the crushed rock candy is just as white as sugar

This is because some light is reflected whenever light moves from a sugar granule to air or vice versa. The randomly oriented granules reflect light in all directions.
