Luma features hand-blown glossy Opal glass with a stunning ``halo`` clear-edge effect. Besa’s easy-to-use bayonet mount secures the glass diffuser to the aluminum fitter with a ``twist & lock`` action. Our Opal Glossy glass is a opal cased glass with a contemporary polished finish and opal inner layer. The tranquil glow has a low key harmonious display that exudes a warm mood. When lit the glass is vitalizing as well as stylish. The Clear edge accent shimmers and sparkles from the light source. This blown glass is handcrafted by a skilled artisan, utilizing century-old techniques passed down from generation to generation.
