Organic honey is produced from the pollen of organically grown plants, and without chemical miticides to treat the bees. Buying organic honey ensures that you avoid contact with pesticides that may be sprayed on or near the plants visited by honeybees.

Crystallization of honey - is a natural process of 100% pure honey. Honey is a supersaturated solution made up of two natural sugars: glucose and fructose. The proportions of these two sugars are characteristic of the plants the bees fed on to make their honey. It's the glucose that crystallizes, so some types of honeys are more resistant to crystallization because they have low glucose https://www.wired.com/2014/03/crystalized-honey/ The truth is crystallization of honey is a natural and uncontrolled process.

During crystallization, glucose sugar which is naturally pure white, separates from water and becomes crystals, while fructose remains as a liquid.It's the over processed, commercial blended honeys that do NOT crystallize. Crystallised honey has been tampered with (by adding sugar or jaggery) Honey crystallises in cold weather due to its glucose content. Simply placing the jar in warm water brings it back to its liquid state. In fact, in certain parts of the world, crystallised honey is used like a jam.Please check the internet as well for research and discussions on the same http://www.benefits-of-honey.com/crystallization-of-honey.html , http://scienceline.org/2007/04/ask-westly-crystallizedhoney/

The residue formation on top of the honey is nothing but pollen, naturally found in the honey. When honey is left untouched for a long period of time, the pollen forms a thin film on top. Simply stirring the honey will make the pollen dissolve. In fact, more and more people today consider bee pollen to be a superfood. In many countries, bee pollen is consumed as a distinct item.

This question is better addressed by a doctor. While honey is better than sugar, we are not medical practitioners and therefore cannot advise it as suitable for diabetics. Please consult your doctor for the above.
