Many sailor's Valentines were made as tourist keep sakes created mostly on several islands but this style of shell ornamentation on boxes and objects , started as early as the 17th c , becoming more fashionable in the late 18th c and then reaching a zenith in the Victorian period, especially in the UK.
Later on in jewelry boxes like this became fashionable during the Edwardian through thirties , mostly as tourist items picked up in beach areas of America or the Islands. Today , there are many contemporary shell artists and this has again become a relatively wide spread design theme. Those made by artists that practice the shell craft and those created across the world by shell artists as export items.
