These are the little baby champagne studs I purchased from kleinkath. (Thanks KK!!) They're in yellow gold and we are guessing they are 0.25 ctw. I will probably have them reset into different mountings, but they are very sweet and sparklie diamonds!!! I would guess them to be about a C3 champagne color.
For some reason in the ear shots they look very light - almost faint yellow color - but the other pictures show thier true color better.
Also pictured with my 0.44 ctw G / SI princess studs for comparison.
