28mm Sun or approximately 1-1/8 inches across with a clear center and facets spanning out from the clear center. Faceted both front and back with a slight rounding. This sun prism has the most facets of any I have seen coming from the center. This unique cut is produced by an Austrian maker other than the famous maker. The more facets the more rainbows a prism produces and this one creates loads of rainbows. Perfect size for a pendant. There is a hole at the top to hang it by. Your prism will come gift boxed with a bow as pictured.
