Top Gem Rainbow Duck Creek Boulder Opal 55.3 ct
This opal was mined in Duck Creek in the 1980’s. Mining efforts there ceased due to being fully mined out until since recently some miners have revisited old mine sites however not much was found. This boulder opal is full faced meaning there is no break in colour with ironstone showing; other Boulder mining regions rival this level of quality boulder. Such a large piece of full faced boulder opal like this is very hard to come across. This is a true collectors opal that is very hard to even find on the market.
