Instead of cutting diamonds (which are usually out of stock and inflated in market), buy a needle and put your cash stack in your inventory. Buy as many tanned red d'hide you can and make d'hide chaps. Making this give close to cutting diamond xp and you actually make a profit of a little over 7000gp per chaps so save them! Keep making and banking. Once at 99 note your chaps and sell them to general store for profit!
