My son and I have each pulled a class ring this year, so far. Mine was the silver valadium... His came out looking gold! We looked and looked for a hallmark, and could only find what looked like GU with a circle around it. Took a few hours of digging to figure out it was GV, not GU.
The first indication it wasn't gold was the VDI. It showed up as a 47. 47 on what was a 17 gram ring. That's odd for gold. Should have been higher.
Second was the fact that the underside of the ring had a slight silver tinge to it. Like it was so highly polished the gold color was hard to see.
The acid test was inconclusive, but it "felt" weird while scratching. That was clue #3.
Internet offered next to nothing for a 2002 ring...
While researching "valadium" I came across a reference to "Golden Valadium" which is a processed stainless steel to give it a golden look. BINGO... GV = Golden Valadium.
What a complete bummer for my kid (who found this particular ring)... even at 10K, 17 grams would have been awesome!
