I will be in Melbourne for only 2 days and would love to pick up some unmounted opals for earrings, rings and pendants for my two daughters and myself. I like crystal, black and boulder varieties. I am looking for wholesale or near wholesale prices (I am not in the industry) and not too expensive. I have a very limited time as I will be with my family and they hate to shop. I searched the internet and did not come up with any prospects. Any recs would be most appreciated, thank you.
