Glittering Sterling Opal Gemstone Jewellery by Rananjay Exports

Sterling opals are predominantly green. They show unique patterns in the form of snakeskin or honeycombs, with black potch lines. The hardness of Sterling Opal jewelry  is similar to that of naturally occurring opal. One must note that there is a huge difference between synthetic opals and imitation opals. Synthetic opals are replicas, having the same chemical composition, amorphous structure, and gemological properties as natural opals. Imitation opals, on the other hand, mimic the look of an opal. An example of imitation opal is Slocum stone which is glass made of tiny filaments inside.
