Opal is the birthstone for October. I love Opals, but of course nice Opals. Not all Opals are nice. Some have no play of color and appear milky white. I do not care for these opals. I own one very nice Opal but it is a triplet, which really is just a slice of really fine quality opal cemented to usually Spinel or Quartz. Australia and Ethiopia are the two places in the world that offer the finest quality Opals. Watch the videos below to see what I mean. I have never seen a faceted Opal as fine as the faceted Ethiopian Opal shown in the video. My oh my it is stunning!
