<p>Because the stones in the inside of the hoop are set concave and the setting in the front are convex, the its necessary for the spacing in the inside to be greater in order to accommodate the same size of diamond.</p>

<p>&nbsp;</p>

<p>We have looked at actual castings.&nbsp; For instance</p>

<p>&nbsp;</p>

<p>Your E43754-6, Our H031701</p>

<p>Fron takes 2.8mm, no problem.</p>

<p>However, the inside takes 2.5mm</p>

<p>I wonder if we can solve this increasing the spacing upward toward the end of the hoop?&nbsp;</p>

<p>The same should be the case in the other one Your E48377-3, Our H031703.</p>
