This is one of the most common questions we hear, and a very important one at that! All Landstroms Original Black Hills Gold Creations bear the following manufacturer’s marking:
![Landstrom Logo Landstrom Logo](https://blackhillsgoldblog.com/wp-content/uploads/2010/03/Landstrom_L.png)
And all Landstroms vermeil jewelry is stamped with the following:
STER+12K
Other registered trademarks from component companies in the Landstrom’s family include:
BH GOLD JCO
BLACK HILLS GOLD JCO
and the original F.L. Thorpe brand jewelry is marked with:

These trademarks go back to before Ivan Landstrom consolidated the various Black Hills Gold companies which are now Landstroms. Some resellers claim to include a “Landstroms Certificate Of Authenticity” with each piece. Be wary of companies making such claims because the only things that Landstroms includes with your original Landstroms Black Hills Gold jewelry is the distinctive, white Landstroms box and the following informative fold-out:
