刚sa回我的: We can add a small ring to make your 16–18-inch chain adjustable, although it is an extra cost. I checked in with my service team and it would be $55 for silver chain and $110 for gold chain. I hope this helps! And of course, if you have any other questions feel free to let me know.

真的是太overpriced了,110块在普通珠宝店都可以买一条14k不细的金链子了。一个小环才0.几克啊
刚巧中午吃撑了看到这里突发奇想想算一下一个小环有多重...
18K金密度 16.5 g/cm3 看这个坠子估计用的链子配的小环最大可能是26Ga的,直径0.404mm,r = 0.202mm, 横截面积S = Pi*r^2 = 0.128mm^2 圈的直径姑且按D=3mm算,因为都是估算就无所谓内径外径了哈... 那周长 l = Pi*D = 9.42mm m = ρ*S*l = 16.5/1000 * 0.128 * 9.42 = 0.02g 如果D=3.5mm,m=0.023g 如果D=4mm, m=0.027g,按今天的18k金价算,m*$41.40=$1.1 。。。。。 没算错吧? 然则以上只是理想中的用金价...
然后加圈。先切开一个小环,拿下来,把大圈换上去,然后焊。不知道T家现在是用激光点焊还是手工焊... 激光点焊又快又容易,国内貌似近几年普及蛮快的,不过首饰用激光点焊机很贵,从大几千刀到两三万刀的样子,用那机器肯定也得收点儿费吧... 手工焊比较tricky,收个几十块工费就更合理了...
MM你太可爱了🥰😂
