Celtic Design Pewter Brooch Aqua & Blue Stones

Beautiful and classic, this brooch features a celtic style design and aquamarine coloured and dark blue stones. It is a medium size brooch abut 3-4 fingers wide - see measurements below. Has a long pin and clasp at the back. Has one flaw - a small crack that you don't notice unless it is pointed out as it blends with the striations design around the sides of the pin and a dent- see photos. There are some variations in the metal around the sides that are part of the celtic design, but one of them is a dent. Measures 5.5 cm across. Composition - I do not know what the stones are. I assume they are glass. This was a gift and I recall the box stating it was pewter and purchased from a store in the Maritimes.
