So i give you two stones. Can you tell me which one is synthetic? It's a marketing term only. We don't call the gold used in the ring as man-made, but it is certainly blended by man with other elements.
No, but what does that matter? It mainly comes down to cost. If you give me 2 diamonds that are absolutely equivalent in terms of size, clarity, etc. and tell me that one costs $6000 and the other $600 then I can tell you which one is natural and which one is synthetic. I want the $600 synthetic one.
