Victorian Bi-Colour Blue/Yellow Sapphire Signet Ring amber it's a beautifully crafted pieceDATE: Victorian, c. 1890 A remarkable Victorian solitaire signet ring set with an unusual bi colour cushion cut sapphire. The stone is certified natural no heat (3. 26ct), mostly an intense deep blue but with a vivid yellow triangle pointing towards the centre. The dramatic colour zoning is unexpected, and adds great character to the stone; it's mounted in a late Victorian 15 karat gypsy signet ring, made in England circa 1890. STONES 3. 26ct Natural
