Brilliant! What would you appraise it at? Just a rough estimate if you could
That is impossible to do with out knowing several things. I need to know the alloy used ie. gold. silver, etc. Need to know diamond carat weight and minimum grade.
If it is sterling with low quality diamonds, I would not pay more than $100-150 for it new. Even if diamonds were middle of the road, same.
If 10K gold with decent diamonds maybe $300-350 just because of gold prices.
Remember rings that have their diamonds set pave & channel are usually lesser grade diamonds because they use quantity to make it "sparkle". It is a way for jewelers to get rid of their lesser value smaller diamonds easily. Not a bad thing, just a better way to present them.
Most diamonds these days are not the quality of old diamonds. When I want a good diamond, I usually buy an old diamond of VVS or better quality and F or better in color, then get it re-cut or reset. But that can be very expensive.
Some of the better diamonds today are coming from Northern Canada. A personal friend of mine in Edmonton is the supplier for these diamonds almost exclusively. Polar Ice Diamonds. I have been to his personal office an seen thousands upon thousands of carats of these diamonds being graded.
I am very fortunate having this gentleman as a friend. We met because we have a mutual interest in Japanese & Chinese antiques. And he has been a mentor to me for many years in both diamonds and antiques.
I have studied and collected antique jewelry for close to 30 years now. It is probably my number one hobby. And I make a little cash from it as well. So now you know how I learned about gems and jewelry.
One more thing to add about the ring. This style of ring is not a good investment. It will never gain in value. It would be much better to get a nice solitaire diamond of decent quality than a bunch of cheaper pave set diamonds.
Hope this informs you a bit and good luck with whatever your intentions are.
