No, black hills gold jewelry is not worth as much as 14K gold jewelry. The cost of 14K gold jewelry will range from $50 to $945 while that of black hills gold jewelry prices range from $70 to $300. The value of jewelry is usually determined by the weight and the number of karats.
Whell, i am not sure but I would think that Black hills gold can also be 10k or 14k so in that regard it would be the same. Black hills gold rings are beautiful and unique and made in one area of the US. In that regard it may even be worth more. JMO
