Fire opal looks like the flame when they under lamp light, so we called them “”fire””. These opals are laboratory created,they are not fragile as Natural opal,they barely have quality difficulties.
Metal material is constructed from real 925 Sterling Silver,you won’t have allergic Response to it,it never drop color,this keep it will last for a long time. These are so beautiful. The stone and cut are just remarkable. Would also make a terrific gift.
