Are these dyed freshwater?

I recently received a full vintage jewelry cabinet from an aunt who thought I could potentially make a few dollars to help during with the holidays by selling it and its contents on Marketplace. I don't really wear jewelry myself aside from my wedding ring so I've had to research nearly everything just to be able to accurately describe, post, and price any of it. The largest portion of jewelry is mid-quality costume jewelry. I imagine she saved the higher-quality expensive pieces for herself or to pass to her own kids, but I was able to sell a bunch of gold pieces for a decent amount to a local jewelers. There are a few pearls pieces that I'm still struggling to identify however.

There's a Michael Kors necklace (not shown) that I'm almost certain are not real pearls and these others are much different in nearly every way. I'm not even certain this bracelet has real pearls at all either, but I thought since I'm asking about the other sets then I could at least include it. The necklace pearls are heavier, have varying colors, and feel/sound natural. None of them have pearls that are uniform in shape. I think all are freshwater, which I think means the black ones would have to be dyed if that's the case. My husband thinks they aren't dyed (based on his vast knowledge of watching a guy on YT lol). Pearls on both the black and pink necklaces and stud earrings feel/look similar to each other, which is another reason I think they probably are all dyed freshwater. Unfortunately, I don't have any measurements of the pearls themselves or the necklace lengths other than the coin comparison photos, but the black strand is exactly 2x the length of the pink strand. There's no packaging, papers, clasps, or stamps/markings included on or with either set. The delicate bracelet has a clasps but it doesn't have any markings at all. I can't tell what the other beads on it are made from, but none of the materials seem very high quality. My aunt doesn't remember anything about the bracelet's origins. And with the sets, she only remembers that she bought them in-person somewhere years ago (not online or from any second-hand source) and that she "thinks it was in Hawaii. Or maybe Mexico?"

Set #1 - Black pearls; 1 single-strand necklace (2 different photos of the same strand) and 2 pair of earrings



Set #2 - Pink pearls; 1 single-strand necklace and 1 pair of earrings (different photos of the same necklace/earrings)



Item #3: White pearl? bracelet



It's really important to me to not misrepresent them or request a price that's much higher/lower than their actual value. So if anyone can help me identify what type of pearls they are and if possible, a reasonable price range for each individual set and the bracelet (if that's allowed), then I'd be super appreciative. A huge THANK YOU to anyone still reading my extremely long-winded post or taking the time to help educate/inform me!

This is easy.
All of them are cultured (not natural) Chinese freshwater pearls with no bead nucleus. The first 2 sets were cultured in Hyriopsis cumingii, the Trianglesail mussel shell. They were commonly sold in the '90s and first decade of 2000s. After that the Chinese began producing rounder pearls.
Set 1 dyed
Set 2 natural color

The bracelet is "Rice Krispie" pearls, older than the other 2 sets. These were sold during the 1970s, '80s and early '90s. They were cultured in Cristaria plicata, the Cockscomb mussel shell. I think the clasp and beads are likely gold-- I have a bracelet like this, minus the black beads (which may be onyx). I received it as a gift in the early 1980s.

Value for resale is not going to be high. All of these are very common. Your best way to determine how to price them is to check eBay for SOLD similar items -- that will tell you what people seem to be willing to pay these days for such items. If the bracelet clasp and beads are indeed gold, the current high value of gold may give you a better price than otherwise. Measure the bracelet accurately-- mine is rather small.

I agree 100%

I actually saw a necklace very much like #2 yesterday, on the neck of the checkout clerk at BJ's. The necklace had belonged to her late aunt so it was very sentimental. For once there were few customers, so we had time for a nice chat about pearls, Pearl Guide and the Pearls As One course. I hope she drops in to check out PG and maybe post photos of her necklace.

Thank you ~ This helps me a ton!

It makes a lot of sense when they were common too, since as I'm going through the rest today, much of the costume jewelry seems to be from like '80s - '90s as well.

Even if they aren't valuable for resale, they sure have been fun to research. I truly had next to zero understanding about pearls aside from very basic knowledge about how they're formed - seeded or naturally occurring. So all of this has been such a treat to dig into a topic I wouldn't otherwise have had an organic interest in. You've all been invaluable to that so THANK YOU AGAIN!
