I love Heidi Klum's engagement ring. I think it's truly unique and different. What I love is the tone on tone aspect. She has a beautiful yellow diamond set in yellow gold with vivid yellow diamonds down the shank.
If you want to get a look like Heidi, you can purchase a yellow diamond ring and have it set in yellow gold or you can opt for another stone like beryl or citrine or something else in the yellow family and have it set in yellow gold with pave diamonds around it. I love that Heidi chose something different and totally set the trends for fancy colors.
