I think they are two different looks, and it's what you're after.does anyone have mod shots of their pave vintage alhambra pendant in rg or wg? which metal do you think suits the piece more?
To me, any white metal (white gold or platinum), makes the piece a "diamond piece". That's why white metal/platinum is often the choice in high jewelery diamond pieces. The focus is solely on the diamonds.
When you use RG with diamonds, the piece becomes a blend of metal and diamonds, a jewelry piece. Your eye now has two colors to process, the RG around the diamonds and the diamonds itself. You will definitely see the RG if that is what you want. It's very pretty as well, but you definitely see metal. It's your preference.
Often times these days with pure diamond pieces, people don't want to see metal and only highlight the diamond.
Most people like to match their metal when wearing jewelry and that's what drives the choice. However, if you are open to any choice of metal and do not care about matching, hands down... I think WG with diamond pave is stunning. Super sparkly as the eye focuses solely on the diamonds.
