Talk:Pearl

message: Would it be a good idea to have a separate article on calcareous concretions? Not only does the pearl article have an entire paragraph devoted to the largest "pearl" ever found even though it isn't really a pearl at all, but there is also an entire paragraph on conch pearls which are also calcareous concretions and not true pearls. Besides, there are other types of calcareous concretions or non-nacreous "pearls" such as melo melo pearls and scallop pearls, so there might be sufficient content to justify its own page.
And if the consensus is that calcareous concretions deserve their own page, what should it be called?  In my opinion, "calcareous concretions" is too technical and intimidating, but "non-nacreous 'pearls'" might be misleading. Thoughts?

message: Pearls can be manufactured by hand.  In Manacor, Mallora (Spain) there are pearl factories that makes 'Majorcan pearls'.  These are made with a glass centre, onto which the layers are added one by one.  The pearls are polished extensively between layers to remove any imperfections.  As far as I remember, the material for the layers consists of such things as fish scales... — Preceding unsigned comment added by 80.242.32.51 (talk) 12:50, 5 September 2003 (UTC)

Anyone know what this is supposed to mean? Also, why are Tahitian pearls known as Titian pearls? There's no explanation anywhere, and that makes it seem to me that the link to Titian is wrong. FireWorks 19:11, 29 December 2005 (UTC)
replies: text: Layers of nacre. They are deposited on the shell bead. One layer is a few micron thick. The thinner the layers, the higher the luster. The thicker the nacre (total of nacre layers), the higher the luster. In cold water, the layers deposited by the 'oysters' are thinner, hence the higher luster on akoya pearls (compared to south-sea pearls luster for example). Effisk 21:31, 2 December 2006 (UTC)
replies: text: okay I must admit my comparison between south sea pearls and akoya pearls wasn't appropriate. The concept that the colder the water - the higher the luster is still valid for a given oyster species though. Effisk (talk) 11:58, 12 December 2007 (UTC)

message: I think we need a short explaination of what causes different color pearls to be produced. Kerowyn  Leave a note  08:57, 22 October 2006 (UTC)
replies: text: Color of pearls primarily depend on the 'oyster' or mussel species. Pinctada margaritifera will produce darker pearls (Tahitian pearls), Pinctada maxima will produce white or golden pearls (south-sea pearls, depending on the subspecies, 'white-lipped' or 'silver-lipped'), etc. Another factor is the nacre color of the donor mollusc (mollusc whose mantle tissue is implanted (grafted) along with the bead. That is for natural colors. Effisk 21:31, 2 December 2006 (UTC)
thread_title: Color

message: this page does not have stuff about how pearls are retrived!
Needs to be added!
:Depends. If the 'oyster' is not be reimplanted with another bead, then the oyster is simply open and the pearl retrieved by hand. The mollusc obviously dies. If the 'oyster' is reimplanted, which can happen up to 3 or 4 times depending on the species, then the process is quite similar to the implanting (grafting): the oyster is held slightly open, a nucleator (the guy who implants the bead nucleus) cuts open the pearl sac using a sharp blade, removes the pearl, then implants a new bead (usually of the same size as the retrieved pearl) in the pearl sac. Please don't hesitate to add this to the page. My English is not so good... Effisk 21:31, 2 December 2006 (UTC)

replies: text: It isn't a "pearl" in the technical sense because edible oysters don't produce nacre (it is then called a "calcareous concretion"). It does not have the luster, orient, etc. that real pearls display and which make them valuable. So yes, its only value is as a novelty, and its uniqueness to your eyes.

What I WOULD suggest however is to create some info pages (in due time) dealing with individual pearls such as Keshi, Melo, Tahitian etc etc. Colors are not really a way to structure pearls (one can think of natural/cultured, saltwater/sweetwater etc).

message: I read in the pearl hunting section that some Spanish conquistadors came across a "bed of pearls". I haven't found an explanation of what a "bed of pearls" exactly is, but the first image in my mind is that the pearls where just lying there in the seabottom, outside any mollusks. Since i can't find a reason in the article why the pearl would be 'released' from the oyster, I assume I am wrong... But still, i'd be grateful for some clarification... Thanks! El edgar (talk) 10:53, 10 May 2008 (UTC)
replies: text: I think it would better be described as a "pearl bed", not bed of pearls. In the days of the pearl divers, pearl beds were where natural pearls were collected. These were areas with high concentrations of pearl-bearing mollusks and (unbeknownst to the divers) a relatively high parasitic content in the water - parasites being the catalyst of natural pearl production.JPShepherd (talk) 22:36, 24 June 2008 (UTC)

message: While it is true that commercial pearls are produced primarily by bivalves, not gastropods, at present there is neither a WikiProject Bivalves nor WikiProject Molluscs who could perhaps keep an eye on the quality of the biology (rather than gemology) information here. Therefore I am rating the article "high importance" in the gastropod project because the article is so frequently consulted (2000 people a day look at it currently). I hope this will inspire members of our project to check and improve the biology side of the article as best as they can over time. Thanks, Invertzoo (talk) 14:30, 6 February 2010 (UTC)

message: The present text on cultured pearls seems inconsistent on how they are formed.  It begins by saying they are initiated by a tissue graft, but it goes on to say they are formed around a bead.  In fact, I understand that both methods are used, but the article should be clearer about this.  The pearls resulting from the two methods may also be different, as the 'tissue implant' method is likely to require a thicker growth of nacre before the pearl is 'harvested'.109.158.46.214 (talk) 14:33, 12 April 2013 (UTC)

message: The last para of the lede doesn't make sense; I suspect that a sensible sentence may have been added to it, without paying due respect to the surrounding prose, thus confounding innocent visitors. As a consequence, I can't tell what kind of object is considered to "have no value except as curiosities". Is it funny-shaped pearls? Pearls from mussel shells? Pearls that lack lustre? (I think lustre is probably the thing at issue, but this para doesn't mention it - the word "shine" is used, but I think in this context that's not really enough). We are discussing here objects that are generally considered valuable, so we should be clear about this matter.
I suppose this paragraph is a palimpsest (like most of Wikipedia). I haven't tried to use tools to figure out who made what changes; I don't think anyone is at fault. The only citation is to FTC rules. Can it be deleted? Should I just delete the para, and wait for someone to complain?
