It depends on the sound of the target.. but if you do not dig it all you are going to lose out on a potential great target..
Persistence will pay off.. In the past I would pass on digging up certain targets but now I dig it all.... and did it pay to grid the the area!
Thanks for the comments and looking.. GL everyone..
I did not test the ring, but considering the size,and weight (3.5grams), I am pretty confident its the real deal. Plus all the hallmarks, ie.. copyright (c), Cartier, the size, Au750 and SN.... Does anyone recommend a gold testing kit? or for that matter a diamond tester? Thank you in advance..
