finding two 10's to match may be difficult. plus, to be honest i think i like the idea of a 20 hammered gold motif (undecided on YG or SO WG) and a 10 motif stone added to the mix for an interesting pop. i feel like for me, it makes the. most sense. so id like to re-add the carnelian 10 to my collection at some point and a malachite 10 and get a 20 motif in a foundational color- meaning full on metal, no stone (unless it's diamond!!) but now that WG guilloche is on the table, i am in trouble because i have a 15 YG guillcohe (10 motif and 5 motif) and wonder if a 10 motif WG guilloche might not be stunning on its own or mixed with the YG i have.
