It's really hard to judge pearls that are photographed against a dark background; the luster and surface just don't show up well. Can you re-photograph them against a white background, like a paper towel? Include close ups of any flaws or loss of pearly coating. Please photograph the orangey looking pearls I see in the first photo-- what is going on there?
Do the clasps have any metal mark on them? 925, 14K etc?
Where did the pearls come from-- is there any history you can provide?
Also see what I posted in another recent thread about some tests you can do for yourself:
1. Holding 2 of the pearls, rub one gently against the other. Genuine nacre offers a little bit of resistance, which some people call grittiness, while imitation pearls glide easily on each other.
2. If you have a loupe (10x magnifier), look at the surface. Genuine nacre is very smooth while imitation pearl coating is coarser, a little like orange peel. If not sure, compare what you see with a known-genuine pearl or a known-imitation pearl.
3. Look at the drill holes.
• With imitation pearls you may see swirls of excess coating near some drill holes. (Not necessarily true of the best imitations.)
• The pearl may be beveled toward the drill hole. I think this may be the case with your pearls, judging from the shapes-- they look a little flattened near the holes. (Also not true of the best imitations.)
• Sometimes the coating is peeling near the holes (or elsewhere) if the pearls have been worn a lot. Imitation pearl coating is flaky and thin. You may be able to see the glass bead underneath.
