KathyK:

Interesting.  My main question about this would be, why would 
Dumbledore need to hold onto the ring?  Why not just toss it through 
and be done with it?  What advantage was there to holding onto it 
and losing the use of his hand versus just losing the ring 
altogether?  If putting the ring through the veil destroyed the 
horcrux, there doesn't seem to me any real need to hold onto it.  He 
doesn't exactly need the ring to show Harry as proof that horcruxes 
exist or that LV is using special keepsakes to store parts of his 
soul.  Harry's seen the memories, the diary, and trusts Dumbledore.

Unless Dumbledore was unsure the veil would do the trick, and 
examining the ring after it crossed the veil was the only way to be 
certain Voldemort's soul was no longer there.

KathyK, begging forgiveness if she's missed something right out of 
canon as she's yet to read HBP for a second time.  For shame. ;-)
