London Blue topaz occupies the deepest, most sophisticated position in the topaz color family - darker and more complex than sky blue, richer than Swiss blue, it reads as a genuinely serious gemstone choice rather than a pale simulant of sapphire. In a 10x8mm emerald cut, that color depth is displayed at its most impressive: the step facets create long, clean light returns through the deep blue stone, showing its transparency and saturation simultaneously. This solitaire ring in rhodium over sterling silver sets the London Blue topaz cleanly, the cool white metal complementing rather than competing with the cool blue stone. Nearly half an inch across, the stone makes a statement that smaller topaz cannot. The rectangular step cut gives the ring its architectural quality - designed rather than decorative. Available in sizes 5-10; not sizeable. For the woman who wants blue gemstone quality at a price that reflects the material's honest value.
