Hi there Natasha... Take a look at these and let me know what you think.
I already added Sterling Silver ear hooks to these and complimented the sterling with silver wire intertwined with the gold to balance out the colour variation. So the S.Silver earhooks match the earrings beautifully.  I also added the Pink in,  on two sides for balance and think the combination is fab. ( I used light rose Swarovskis which enhance the gold but does not over power it).
As for the rest of the design.. They measure in length.6.8cm
