At the top of the henshin rod, there is a closed frosted white crystal rose;
when it is open, the royal purple symbol of Saturn is projected above it. 
Its base is a purple-tinged white Star of David on gold, and inside it is the
purple sign of Saturn.  The length of the stick is violet, and there is a
golden string coiling down it.  The base of the stick itself is a couple of
flattened circles, the top one gold, the bottom one pink.  That is Hotaru's
Saturn Eternal power rod.
