They are not listed on our web site, but we (the Scottish Tartans Museum gift shop) typically have a selection of heather gem jewelry in stock. A mix of sterling silver and pewter, celtic cross pendants, celtic knot brooches, thistle brooches, that sort of thing. Your wife is correct, very nice stuff and not that expensive at all.

For the gents we even have some heather gem kilt pins and heather gem capped sgians dubh!

Aye,
Matt
