These sapphires are a beautiful gray, gray-ish blue and white color. Colors do vary. In between a few of the stones are two sterling silver “pringles”. Ear wires are also sterling silver. The sapphire is a common gift for a 45th wedding anniversary. This is because, for centuries, sapphires have been known to be a symbol of innocence, longevity and a talisman for good health. The stone represents prosperity, beauty and inner peace.
