r/pearls

we found a lot of my grandmother‘s pearls when cleaning out her house. They are all authentic and none are costume jewelry. Are these worth anything?

Hello everyone! My mother gave me this pearl necklace a few years ago, and I just rediscovered it while clearing out some things. She can't remember if these are freshwater or saltwater pearls. Is there a pearl expert here who could help me identify them?
The clasp is stamped "375 JKa", which I believe indicates 9k gold . The necklace is 37 cm long. I am also looking for advice on how to properly clean and care for them. While I know I can search Google, I would love to get practical advice from fellow pearl owners who know exactly how to look after them.

Thanks in advance!

found them on an old jewellery box from when I was around seven, I did the teeth thing and they felt like sandpaper and they also feel cool to the touch at first, but they have no knots between them. I don’t plan on selling them but I would like a new bracelet (sorry for the morbidly zoom on my palm)

I have 2 roughly identical strands, both branded K. Otsuki & Co. I think they date from the mid 60s to early 70s when my grandfather would have been stationed in Japan. Rather than a clasp, both strands are terminated with red wax seals with JCE stamped on them, I do not know what these initials mean. They are not individually knotted. I assume the unfinished nature means they were probably sold to be restrung by a jeweler.

The largest pearl is ~7mm across and the smallest ones are ~3.3mm. The drilled holes are small and unbeveled, and they do feel rough on the edge of my teeth.

Anything you can tell me would be much appreciated.

For feeling, they dont feel plastic and doesn't sound 'plastic' when they are clumped together.

Hello everyone! I’m planning to buy a pearl necklace for someone, and a friend offered to sell me this one. The problem is, I don’t know much about pearls, so I’d really appreciate any insights or advice you can share about it! It has a total of 52 pearls and is about 18 inches long!

My main question is what type of pearl are these and how much does it cost so I can avoid overpaying !

Inherited these pearls from my great-grandmother. Do these look like cultured pearls or naturals? What would you estimate the price to be? They smell kind of funny (probably because of age). Would that hurt the value?

Sorry for the quality. My phone didn’t want to focus on something so tiny.
But I bit into this today while eating oysters. Pretty scary when I heard the crunch. But nothing seems to have chipped. This little ball is very round. And I think I can see a thin layer of nacre. Or is this just a round shiny little rock I just bit into?

Edit: please feel free to remove if this doesn’t belong here

I picked up this vintage ring and I’m trying to identify the centre pearl (along with the hallmarks).
Inside the band, there is a five-pointed star inside a circle, and right next to it is something that looks like 81/18 stamped inside a hexagon. From my research, this looks like a Spanish silver hallmark system (?). Any insights on whether the pearl is genuine? It shows south sea pearl when I google it.

Mia nonna mi ha dato questa collana ma non capisco se sono perle vere. Sotto i denti mi sembrano un po’ sabbiose e se le sfrego tra loro esce una patina bianca ma non molta. C’è una perla che sembra bucata e l’interno è sporco ma sembra che ci sia un po’ di luminescenza. Forse è sostanza perlifera sporca o forse no. Chiedo aiuto

Tahitian culture Black Pearl necklace, round 10mm-12 mm, 18 in length

I've been shopping for a while and this proce seems considerably lower then what I'm used to seeing for 10-12mm round. Am I missing something here? This seems like a good deal.

Couldn’t add more photos to other thread-so here is new thread. I tried to wipe with soft cloth-got a bit of the dust off, but they still need a good clean.

Title says it all thank you

Hi! This is my mother’s necklace, she passed many years ago. I miss her a lot. I don’t know what kind of pearls they are. The necklace is too short for me. I would like to make it longer so that I can wear them. Any advice in DIY techniques?

My dad found these pearls in an old building he was tearing down for a neighbor. There were actually a few nice pieces in the can this was found in. I know they are in terrible condition. So I need to know how to clean them and if you think they are real? Or know anything about them? Thanks in advance. The clasp seems to be broken but the other piece is actually inside the clasp. The clasp is what makes me think they may be real.

Someone gave me a bag of free beads which included these extremely dyed pearls which I was hoping to bring closer to their natural color. I think these are natural given their amorphous shape and they lack some of the signs of fake pearls like peeling around the holes. I have them soaking in mostly water with some dish soap right now. Methyl acetate worked last time to remove dye from dyed quartz. Don't have that anymore but I do have acetone which should work as an solvent on synthetic dyes. But everything I've read says to avoid most chemicals with pearls since they're delicate. Since they're fancy calcium carbonate anything low pH is out. What would be the best way to remove the dye if possible?

Update: it has been like 4 hours, I think the dish soap is working, the water mix is turning greenish. Instead of getting rid of the dye it just might manage to redye the pink pearls light green.

Update 2: Sunlight and hydrogen peroxide could work or damage them so I went digging. Sunlight dulls iridescence but at least doesn't seem to affect structural integrity and a lot of the most dyed areas are on the back so if the soap fails I might turns them on their backs and stick them in the sun for a day. 12 hours and I changed the soap solution. I don't think the pink has lessened just the green. Some of the pink pearls are now showing brown/orange patches, I don't know if this is what the dye was hiding or they are getting redyed by the orange/brown pearls (3 of these). Did more digging hydrogen peroxide is used for commercial bleaching but without a formula and what are probably proprietary methods I'm not going to try it.

Hour 16: yeah the green pearls are definitely turning a yellow/orange/brown color. My current though is that all the pearls had some brown, that's why the manufacturers dyed them to begin with. Interestingly removing the dye is restoring a lot of blue overtones and iridescence to the pink pearls. The solution is now a cloudy teal I don't know why, a dead fly got in but that shouldn't have affected too much. Anyone know how long pearls can stay in the soap solution?

my grandmum and mum passed these onto me over the last few years and i’d love to wear them either way on my wedding day coming soon! x i was just curious if they’re real or no as im no expert of jewels. thank you!

Would love help identifying these-bracelet and necklace have different clasps and markings. But both were grandmothers.
