My great grandmother's OMC (1.44ct, I-J, SI2) solitaire arrived! it is off being reset now. Here it is on my hand and with the heart cut diamond that will go in my gf's e-ring. We are doing matching settings with different cuts of diamond.
Here is mine, it was sold to me as an old mine but the GIA report says cushion brilliant. I was told it came from a ring from around 1910. It is a 1.57 J SI1 with VSBF.
4.00 J VS2 (EGL) -- appraised as GIA L (but shows up very white!) 10.00 X 10.01 currently being set (setting slated to be finished towards the end of December).
