<p>If we can make a few adjustments in the mean time on this particular design;</p>

<p>&nbsp;</p>

<p>1. If you can add sprues in the top centre 1.2mm diameter &amp; 5mm long on each part, this will save a lot of time preparing the piece for casting. See attached picture for reference 2. The first link joining the V-piece on each side ; if we can have it taper from 2.8mm to 1.8mm so that the flow looks better on the piece, at the moment it is way thinner than the end width of the V-piece and doesn&#39;t look right.</p>

<p>&nbsp;</p>

<p>I think that will do it, as soon as I worked out bigger dimensions for larger stones I will send it through for you to give different variations on this neckpiece ito thickness and width.</p>
