I recieved pearl earrings for christmas from my grandma and just out of curiosity I was wondering how much they were worth

I’m breaking into the bridal market with my line of genuine pearl jewelry (see www.sunandmoonpearls.com). The problem seems to be that fake pearls dominate at retail outlets that I’m trying to sell wholesale to and brides either don’t know the difference or don’t care. The irony is that fake jewelry still costs an arm and a leg (as much or more than my genuine jewelry line) So… Part 2: How do I raise awareness without launching some huge expensive ad campaign? (which would increase my overhead). Any ideas would be appreciated!

This company(http://www.hotpenpromotion.com) has so many pearl necklaces jewelry,who knows is this a freshwater pearl or immitation ones?
There is a answer on the website to explain how to distinguish the fake pearl necklaces http://www.hotpenpromotion.com/profile.html

I have a pair of real pearl earrings, the backs are 14kt gold. I also have a real pearl necklace with probably about 36-40 pearls on the strand, and a 14kt gold clasp. I am trying to sell them for as much as possible. What is a reasonable asking price for this beautiful *AUTHENTIC* jewelry? I have never worn them so they are in perfect condition.
