A 9x7mm rectangular octagonal blue lapis lazuli 18K yellow gold over sterling silver tennis bracelet measuring approximately 0.38 inches wide with box clasp - the lapis lazuli tennis bracelet in warm gold where the deep ultramarine blue stones create a continuous rich navy presence at the wrist. Lapis lazuli's deep blue with characteristic gold pyrite inclusions has been prized since antiquity. In the tennis format in warm gold, each rectangular octagonal stone creates a geometric blue link in the continuous line.
