3.61 carats of emerald-cut strontium titanate diamond simulant in a rhodium over sterling silver pendant necklace combines the highest-dispersion white stone available with the architectural step-cut that reveals that dispersion in a different mode from brilliant cuts: the emerald cut's long, linear facets create sweeping reflections that display the strontium titanate's exceptional color-fire in broad, dramatic events rather than the pinpoint sparkle of round brilliants. At 3.61 carats, the stone has the surface area to show both the architectural depth of the emerald cut and the spectacular rainbow-color dispersion that exceeds diamond's. A pendant for the customer who appreciates both gemstone optics and cut sophistication.
