Blue roses are highly coveted flowers, partly because they are quite rare. Thankfully, you can have these gorgeous blue glass roses at any time of the year. Each piece is made of borosilicate glass, which is molded through traditional hand-blowing methods and simple tools. Opaque green stem and leaves complement the transparent cobalt blue petals. The blossom measures approximately 1 1/2'' in diameter, while the stem measures 6'' in length.
