This is a simple necklace featuring rare, round synthetic water opal beads. It uses very beautiful synthetic water opal. The main colors of the play-of-color are blue and green. It also displays a flash effect similar to natural opals. Synthetic opal is a synthetic stone developed using special techniques. It is made by carefully recrystallizing a substance with the same composition as natural stone over a long period of time, resulting in an artificial gemstone with the same composition as a natural gemstone. Although the production environment is artificial, the production process itself is almost the same as that of natural opal. The opal, which takes 13 months to create, has a beauty indistinguishable from natural opal. We use stones with the same composition and equally beautiful as those mined from nature.
