Since I brought the cong with me to Boston, I took a few more photos which may (I hope) shed some additional light on the age of the piece.
Group #1 photos show the inner core of the cong. Taken with flash, note the highly translucent quality of the jade, nice smooth polish, but as you can see there are rings from the cutting instrument. The last photo of the group shows the inner rim/fragment remaining from where the core was broken out. None of the surfaces look recently worked (surfaces appear to have dirt/dust accumulated in some very hard to reach spots).
Group #2 photos show the straight tools marks on outer surfaces of the cong, 2 with flash, and 1 without. These marks are not easily visible to the naked eye and feel perfectly smooth...no roughness. Also, not that the straight lines are cut in different directions in some spots...the maker changed the position of the tool he was using to polish the jade.
Group #3 photos show the inner surface of the 'C' shape carved design. First 2 photos are with flash, and the last photo is without on an area where some dirt/black material has accumulated. The lines are not perfectly straight as to suggest the tool shifted slightly as it was dragged across the surface of the jade. I assume a high speed cutting tool would have left a much more perfect straight cut, but that's only my assumption.
Please comment! Thank you for all the help and advice.
