Lab-Grown Padparadscha Round Faceted Gemstone

Lab-grown padparadscha is made with corundum and delivers its sought-after pink-orange color at an economical price. These gemstones perform at the bench just as a natural gemstone does but, unlike natural padparadscha, is heat-resistant and can be successfully cast or fired in place. Round-cut gemstones are highly popular and the most commonly available. Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
