<p>Hi Julia,&nbsp;</p>

<p>The customer comments are as follows;</p>

<p>Each stone size should have a different size prong, for the smaller ones its not as important, but when it gets to large stones you can not use the same prongs. They need to be bigger in diameter, I am measuring the prongs and they are almost the same.&nbsp;</p>

<p>Also, each time you make a new file for a different size stones, the prongs should be built from scratch and should be proportional to the stone.</p>

<p>Thanks</p>
