I visited the shop in my recent visit to Sydney. I went to a few opal shops in the downtown areas. Didn’t find what I was looking for. Then I stepped into Rockhounds, they have much more variety of opal Jewelries. Paul is the most knowledgeable opal expert I talked during my shopping rounds. I left the shop with the black opal earrings I had longed for many years! Highly recommend the shop!
