To obtain a lot of elements defined in a template all at once, you can collect them like this:
<!-- cut:chest -->
<div>
<!-- cut:diamond -->
<img src="diamond.gif" />
<!-- /cut:diamond -->
</div>
<!-- /cut:chest -->
<div id="box">
<!-- paste:jewellery -->
</div>
list($diamond,$chest) = $se->collect('chest.diamond|chest');
