As to limiting the never ending flood of ' I bought this off ebay for $1 and I think they are natural pearls' and 'I inherited these from...' Perhaps limit the starting of a new thread to someone with ten posts under their belt or somesuch - like posting photos is limited? Or we just agree to...

A few years ago I asked a top genetics biologist why shells and therefore pearls had colour in their nacre in some species, given that there was no male/female sex attraction thing going on; that it is mostly dark at the depths at which shells live: and no eyes to see the colours. But there they...

$180 would be a good price for dyed freshwaters imitating gold south sea. There are thousands of dyed freshwater strands on offer to the trade but most have a brown cast which is very noticeable when you see a tray of them.

For $300 you should be able to get a much nicer strand, even with today's silly Tahitian prices. (and, as you seem to be implying that that is a generic photo and therefore presumably the pick of the lot, what would your $300 deliver?)

Why go with what everyone else is doing? Come up with some innovative and more modern designs? Of all of those I prefer the clean lines of the ones towards the lower middle.

They're quite low quality, not much luster, or special colour, different shapes, lots of flaws.

Tahitians are the opposite of inexpensive at this moment.

They look like dyed freshwaters to me, though the photo is bad. At least ask for an in focus photo on a plain white background before you buy. What does the price tell you?

What is the research project and under what academic umbrella? Is it images you want or actual pearls. It is fairly easy to obtain natural pearls from any of the websites which sell them.

They are stick pearls. They have a strip nucleus. Biwa pearls (pearls from the Japanese lake Biwa) used to be similar in shape but have largely disappeared due to pollution. But the name stuck and got applied to stick pearls from anywhere

Try super glue dissolver. Just splodge onto the glued bit and seal into a ziplock - leave for as long as it takes for the dissolver to work - can be a week. Ziplock needs to be as small as possible and squash out the air.

Works in Google. Don't see them so much these days.

Try it (pond slime)

Sunlight is not white or neutral light. It can be blue, green (rainy overcast) yellow. Sunlight or any natural light photos are unreliable as to colour of pearl.

Faceting and inlaying are neat ways to boost the value of pearls with flaws

Glue does not fill gaps and should not be expected to. All glue work by creating a vacuum which holds the two surfaces together (think of two glasses stuck together) GS hypo is designed to stay slightly flexible I use and recommend a good brand of gel superglue (and get the dissolver at the...

Yes really. Doodling around facebook I found this video.. https://www.facebook.com/reel/745983807485236

You could go so far as to have two rings which fit together so for all day every day you wear the tough stones one then when you want to, you add in the pearl ring. Along the lines of those engagement and wedding rings which fit together.

When those pearls were new to the market they were one value. Now growing techniques have moved on apace and quality is much higher. I can see from one of your close up photos that the pearls are not super-well matched (two pairs on a card). The market has evolved. Those pearls are mostly left...
