There is no recipe for learning this yellow gem cut. Jewelcrafters must discover it through  Sun's Radiance or  Secrets of the Stone (no CD). It is possible to learn this cut from any of the other JC daily cool-downs, but only after learning all of that color's cuts and even then the color of cut learned is randomly chosen from all of the other colors/cuts not yet learned. The most dependable of means of quickly learning how to cut Fractured Sun's Radiance is using the Sun's Radiance cool-down.

Mastery has less desirability than some other yellow cuts, but this cut gem should* sell decently on any realm's Auction House. Blood Death Knights in particular prefer stacking Mastery.

*As a general rule. As always, price is determined by number of suppliers and the healthiness of the realm economy.
