I was looking at a three stone oval & RB ring. The oval was the center stone, with a GIA report H, VS1.. good table, depth, ratio, 2.24 carets.. but... it had a yellow tint. When viewed from the side, the diamond was white. The jeweler and diamond cutter were stunned. They placed a loose oval and round diamond on my hand both having the same color,clarity, similiar stats, etc.. and the oval picked up a yellow tint from my hand.. Is this true with ovals ?? It was a very interesting afternoon.
