At Pressley Collection we use not only the best and brightest diamonds, but we price them lower than available anywhere else.  After each diamond has been independently tested for light brilliance, the top  5-10% in the world earn our Regality title. If you find ANY other light performance rated diamond of equal characteristics at a better price than ours, call us and we will beat it.  After all we carry " The world's brightest diamonds at the world's best price."
