Photo Props and Noticeable Flaws

When I was at the grocery store, I found a little watermelon and thought: I need to reshoot my watermelon tourmaline necklace with a prop.  Much better!  BUT in the sunlight I noticed a crack/chip/flaw in the stone that I hadn't noticed before.  Argh.  So I discounted the necklace by twenty-percent.  Bummer!
