Amber sea glass can come in various shades and even though the colour is still used in the production of modern beer bottles the majority of amber seaglass found will be at least decades old, some pieces could be over 100 years old. The shades can range from a light golden amber to an almost orange amber. Early poison bottles were made with amber glass and were ribbed to alert you to its dangerous contents. The pieces are naturally tumbled by the sea, we do not tumble or reshape the glass. This is why seaglass tends to have imperfections or 'C' marks which occurs from being dashed against the shore. The holes were bored using specialist equipment. The earwires, findings and jump rings used are all solid 925 sterling silver.
