TSP refers to trillion side stones, describing nanosital gems cut into a triangular shape and set as accents. Their bright, compact outline strongly contrasts solitaire center stones. With 57 meticulously calculated facets, TSP nanosital unleashes remarkable light patterns. The transparent material splits light into spectral colors known as fire. TSP nanosital elegantly frames rounds, cushions, and other cuts. For extra allure, designers often embellish with TSP nanosital.
