Comment: Our first and only pair of star sapphire. It was impossible to get both stars on photo. The detail image shows the better one of the two in close up. The second star unfortunately blurs too much on image so we skipped trying to catch it. Pair and not-round star in combination are the perfect storm for a gem photographer, it seems. At any rate this is a rare chance to make a pair of earrings from natural star sapphires.
