I have been sea glass collecting for as long as I can remember and it is my professional opinion that the northern Atlantic typically doesn’t produce much cobalt beach combed sea glass in this condition. I have personally found many sea glass shards of this color on the east coast USA, however most often the surface is very pitted, sand is embedded and they are an irregular in shape. Authentic cobalt sea glass is always in demand. It appears to be a favorite amongst sea glass lovers. This piece is amazing!
