Lime green is an uncommon sea glass color and has a vibrant and energizing beauty. Possible sources for this type of sea glass in Puerto Rico are various kinds of old, vintage soda bottles such as Coco Rico soda bottles. Coco Rico has been around since the 1930s and is a coconut soda from Puerto Rico. It has a long tradition of having been bottled in green bottles which celebrate the color of green coconuts.
Much of the lime green sea glass found on the beaches of Puerto Rico is thin to very thin. This could be because the glass items it comes from where made of a lightweight glass or because the glass itself was not a hard glass due to the pigments used for colorants or for other reasons related to the formula that was used to make the glass. Softer glass will wear down faster than harder glass in the sea. Lime green sea glass from California tends to be much thicker and more than likely comes from old vintage soda bottles.
