Overall Im very happy with my purchase which was the 10k big dogtag, the size is just right and it looks great hanging off my 10k miami cuban link chain. At first I was worried because the dogtag had no gold hallmarks on the piece so I called Frost NYC and asked why, they explained that there were no 10k in stock so they gave me a 14k piece instead (with no hallmark and a bit lighter in weight). They encouraged me to get it tested also so I took it to the Perth Mint and the purity was reading about 58%. So yes I was very happy and relieved to find out that my 10k dogtag with no hallmark is actually 14k. Thank you Frost NYC, Im looking forward to my next purchase from you guys.
