These are a great entry point, to start a collection of genuine Australian Opal. They are fun stones, with good potential, to add value over time. They present a great opportunity to see and feel what these are like, in the hand. They still are suitable for jewellery for the hobbyists, or to just enjoy on a sunny day, when you are showing friends and family members. They carry good colour and may not be perfect, but beautiful in their own right. They are a great entry point, into the world of gem opals.
