nnguye20, if these spots are made of carving dust, they must be easy to remove with water. If you can't, maybe that's a mix of dust and other thing, a glue for exemple, then, try to rub spots with acetone, and more softly with alcohol (alcohol would remove an acrylic painting). Sometimes...

Thank you, GemGeek. Is there conchyoline, as concrete of aragonite crystals?

Georgeous picks, GemGeek! A question : how this pearl's material is called, if not nacre? I believe to know it has the sames components, but aragonite crystals are organised like a radial structure, in reverse of concentric aragonite layers of standart nacre, is it right?

Good eye, Lady_Disdain! as a man, I might add that a little filling with a thin nail file would make tips of hooks smoother, because so rough they are now, I beg they can injure your ears. About colour, I had read in a thread, I don't remember where, that many pale gold pearls entered in Japan...

In french version, Wikipedia signals some of the effects you notice, but in experimentation at high levels of exposure with animals, and says that it doesn't know if that can be observed on humans. Wikipedia don't speak of death. Of course, acetone is not good to make a jacuzzi, but I repeat...

I don't agree, pearlescence : acetone can irritate eyes, sure, and make troubles of consciousness only at very very high levels of exposure, but its hazardous level of general exposure is 2400mg/m3 of air, comparatively, dangerous level of ethanol is 1900 mg/m3, so, usual alcohol is more...

I agree. Acetone can attack only dying, but never nacre, with a little remark : this solvent remove also water, a well known effect on nails when we use it to remove nail enamel, and conchyoline don't like to be dried, like nails ( that's nearly the same organic component). So, it is prudent to...

I have looked at Kongs : he has no loose pearls with such a particular colour. Only one is enough pale, but more pink. That's also difficult to judge Kong's picks, often too much saturated. Lady_Disdain, what is the size of pearl you need?

Yes, pearlescence, but I wonder how dying has gone so deeply. Nacre cut don't show different coloured layers, or nacre nucleus would be dyed, too, in case of dying after cut.

nnguye20, what a space pearl's opera! Imperial topaz (I think), looks nice with your pearl. Sure, it's not easy to drill such hard stones. The machine to make that is very special, expensive, working with ultrasounds and diamond tips. I have several coloured stones myself, several pounds...

So strange to see pale bead in the middle of the cut. If pearls have been dyed before cut, (thick) nacre under surface would have to be also pale colour, and even if they have been dyed after, why these so much different colours?

Katbran, if you have removed good epoxy by this way, you are luky! I'll try that. Now, strangely, acetone is one of the less hazardous solvents for health.

nnguye20, finally, I have found one of pieces of stone I have talked to you (I had given it as a gift for my wife, but I didn't remember that:rolleyes:). Unfortunatly, not the amethyst one, but citrine. These crystals are obtained breaking geodes by a special impact ( with wood or bone tool), to...

I wish that, Pearl Dreams. In Europe, experiment has shown it's very difficult to manage this kind of hazardous substances, mostly to trust people and industries to make it well. The result has been to forbidden their use to private customers, and to make truly hard rules and controls of use by...

Good, lilliefuzzysocks, but problem is to junk the liquid (which is very dangerous for environment, specially water life) after use. Even vapors are dangerous for anybody and any animal's lifes around.

Thank you for sharing, lilliefuzzysocks. I have found chemical composition of this product: diméthylformamide, graded as dangerous for foetus in Europe, and dichloromethane, graded as carcinogenic in Europe, too. These substances are not authorized for sale to private customers, here, even very...

Mmmh, Katbran, looking at the setting of the pendant, if pearl is sticked with epoxy (I beg it's not set on a pin, too much difficult to make by such wrong foundry process), that means metal would be heated up than 230°F, not a good treatment for the pearl. Without to talk of removing glue on...

lilliefuzzysocks, I agree you, so weird to see these pearls on such bad settings! An auction to sell only these pearls could be understood, but an auction to try to value a desaster, that's new! If pearls are well sticked, it will be difficult to make something else without to damage them.

Strange pendant, lilliefuzzysocks, if its pearl is dyed, that's truly a good fake of tahitian. And yet, setting is a rough foundry work and bail thin like a cigarette's paper. Cheap or not cheap? More, in addition with earrings? If these pearls are tahitian's, that's less expensive than usual...

nnguye20, sure GSSP looks good with SoC : the complementary colour of gold is exactly this SoC colour! I have not yet found a piece of amethyst I have and which I would want to show you. It's this kind of crystal keeping a long root behind the tip of crystal, like a tooth, when separated from...
