Antique 5 Stone Sapphire Diamond Ring

This circa 1900 ring was hand crafted of 18 karat yellow gold and features a row of five Blue Sapphires prong set in the East/West orientation and accented by Eight tiny Rose Cut Diamonds set at the top and bottom between each Sapphire. The low profile ring has a narrow tapered band, increasing toward the long gallery which has a scroll design side gallery. The under gallery is open behind each stone for ease in cleaning.
