I have a pair of diamond stud earrings that belonged to my grandmother. She received them from my grandfather on her 50th birthday - she will be turning 95 in June! I would like to turn them into a 3-stone anniversary band but am unsure of the design. Each diamond is right around the .50, round cut, and they match beautifully. Should I go with the traditional round center stone? What about an oval cut stone for the center? Will that look too much like another e-ring? I've also been looking at fancy colored diamonds and like the look but don't know if I should go with something classic. I'm in my 40's but have 11-year old identical twin boys so it should be something that can withstand a bit of rough housing on occasion. Or at least not be something that I need to baby. Any input would be appreciated! Oh, and I already own 2ctw diamond studs or else I would be keeping them as is.
