Deluxe KIOKORI lighted presentation gift box included Moissanite is rarer than diamonds but now grown in the lab to give you a clarity, color, look, and fire that is hard to find in real diamonds but at a substantial savings. Moissanite will pass as a diamond on a standard tester pen electronic device. Diamond has extremely high heat conductivity which means heat passes through the stone quickly. Moissanite has virtually the same heat conductivity that's why it will show up as diamond on a pen tester. Moissanite will never become cloudy, discolor or change its appearance. Moissanite will maintain its brilliance, color and clarity for a lifetime and beyond.
