I tested it for some time and this is what I think
the site is quite cool and easy to use and in my opinion it might be useful but ... the results are not 'correct' so people should not use it to define the 'real opal value' especially those without any opal knowledge
I like the system of categories you have to choose but it's missing few things like some : color mix or pattern types
which mean that in some cases I can't choose the 'right' options

other thing are the results >
in case of Australian opals (especially Lightning Ridge dark and black) the results are generally quite good (the value is much closer to marked value)
and I was very surprised that some prices were very close but still not all of the results were OK and some were quite strange

when it comes to Ethiopian Welo opals the results are waaay off the actual market

- I mean I wish they are real but in 99% of cases it's impossible to sell Welo for what 'they' say

but I'm talking about high quality Welo
