Just on the off chance that anyone happens to have a pair of well cut, 5.5mm(ish) pink gemstones lying around (preferable hot or medium pink, not pale or brownish/purplish).
Cheers!
I have a pair of pink spinels for sale on LoupeTroop and DiamondBistro that would probably fit the bill in terms of color, but unfortunately they are only 4.7mm
