It seems like a few members here own the Tiffany DBY solitaire necklace, and would like to know, how small are the diamonds??? I'm looking into the .5 carat. I have yet to see these in person which is why I'm asking. I really want a solitaire diamond necklace but I don't know if it's worth it to buy it from Tiffany. I know Cartier has a similar style as well. Should I get this jewelry staple from Tiffany? Cartier? Or should I get it custom made by a reputable jeweler?
