Thirteen oval aquamarine cabochons alternate with twelve round, faceted blue topaz stones in this substantial gemstone necklace. The aquamarines show cloudy blue-gray tones beneath smooth, domed surfaces, with pale blue topaz adding brighter sparkle between them. Each stone sits in a simple silver-tone bezel, creating a curved row across the front. A chain of open round links completes the necklace, secured by a lobster clasp. The repeated oval and circular shapes give the design a composed, elegant character, with enough breadth and color to make a confident statement.
