Lime green sea glass is actually quite rare, and is usually only found as thin chips with ragged edges. The only source I have found for rounded thick lime green sea glass is the island of Bonaire in the Dutch Caribbean. These unique pieces are called “Authentic Bonaire Limes.” (and for good reason) Their brightness is spectacular. You may think you have a piece of lime-green sea glass, until you put it next to a Bonaire Lime, then you’ll truly see the difference.
