diamond and sapphire eternity band?

[lover in athens]

it has been forever since i''ve posted on this part of PS...but i''m looking for some help/advice...i would LOVE to find a beautiful/reasonable diamond and sapphire or perhaps diamond and aquamarine eternity band/RHR (mother''s day gift in honor of my son; hopefully to be joined by a somewhat matching pink sapphire/diamond band in the near future when his sister arrives). i have looked at some of the beverly k rings and i love them. does anyone have any other suggestions on places to look?? i will likely have to go custom unless the ring has a large sizing band (i wear a size 3.75)...

thanks in advance!!
