Beautiful vintage Panetta ring with a large rare genuine tested purple sapphire center gemstone and 20 white quartz gemstones surrounding it. All stones tested as genuine gemstones set in gold plated sterling silver. Purple fancy sapphire are quite extraordinary and far rarer than the more traditional blue sapphire. Unlike most blue and pink sapphires, which need to be heat treated in order to obtain their best color display, natural purple sapphires very rarely require any heat treatment. Furthermore this purple gem tends to change color in different lighting! Brand Marks - Panetta / Sterling Size - 6 Condition - Excellent vintage condition Smoke / Pet Free Home
