This listing has a lovely pair of sapphire earrings! The sapphires are set in a flower shape – 5 sapphires with a center sapphire – and measure ¼” diameter. I could not see any markings on the earrings but I believe they are silver. They have nice long posts (3/8”) with indents on end to hold/help secure the butterfly backs. Very nice (and they coordinate beautifully with the sapphire necklace we just listed as #J624)!
