TSP, meaning trillion side stones, refers to accent stones cut in a triangular trillion shape. TSP quartz provides extra sparkle bordering a central gem, often rounds or princess squares. Their compact triangular outline contrasts beautifully with the main stone. With 57 precisely calculated facets, TSP synthetics exhibit intense light return. The triangular shape contains the “fire” at the stone's heart, emphasizing scintillation. TSP quartz comes in both transparent and bold hues like champagne or smoky gray. Their high refractive quality disperses spectral colors. Thanks to their flawless clarity, TSP accents don’t detract from the center gem. For added interest and brilliance, designer jewelry often incorporates TSP quartz as side stones.
