Cultured Opals

The Japanese have discovered a way to 'culture' the most beautiful fiery, blue Opals. The opal silica structure has almost the same physical and chemical composition as natural Opal but without the water content meaning that it is harder wearing and not so prone to breaking. Cultured opals display fiery blue colours with flashes of green or turquoise which are truly breathtaking!
