Nice quality chain, really dainty but sturdy. Rolo chains are a strong link plus rose gold filled use more copper than regular gold filled and that makes the chains even stronger! 

This chain is 1.4mm and comes with a 5mm spring ring clasp. I also have these in 14, 15, 16, 17, 18, 20, 22, 24, 27, 30, 32 and 36 inches
