A note, Landstroms factory outlet store at 620 st. Joseph st. in Rapid City SD is the place to start to understand its pricing, and the place to go to have worn jewelry restored.
Look for the L 10k hallmark.
I have not seen or know of any fakes of BH tri color gold, all are genuine 10k gold. The difference is in the polish and design. Others than Landstroms just look cheap and overpolished to us.
The suggestion to visit the Homestake Mine/ Sanford underground physics laboratory visitor center in Lead ( pronounced Leed after a vein of ore) is a good one, it is the worldwide premier place in the search for sub atomic and dark matter particles as well as the the largest, oldest mine in the western hemisphere.
