Attribution: The Journal of Gemmology / 2010 / Vol. 32 Researcher, author and photographer: Thomas Hainschwang, Director, GemLab(Liechtenstein). This is not a shell, and it is not a fossil. It is, however, an 84.77-carat natural porcelaneous saltwater object composed of aragonite. This object...

The forum has been strangely silent regarding Tucson/AGTA this year, notwithstanding the terrible tragedy there last week. Who's going? Any Pearl-Guide activities to be planned? Anyone going and not signed up for the AGA Conference should consider registering in order to attend the...

?an apparently time-honored but currently-ignored idea with rare appeal to men. In a recent thread I introduced the writings of Louis Kornitzer to Pearl-Guide. After reading The Pearl Trader I acquired copies of his subsequent works, Gem Trader and The Jeweled Trail, both highly entertaining...

Pearl-Guide is without prior reference to this great book written in 1937 by the world?s preeminent natural pearl personality and trader of a bygone era. I post this in Natural Pearls because of its specific appeal as well as Kornitzer?s relevance to a resurging interest in naturals as evidenced...

In a couple of currently-active threads Tridacna pearls have surfaced. Also, a thread with Tridacna in its title was recently begun by a seller and as quickly aborted. The Indonesian name for Tridacnidae (giant clam genus, Bivalve) is Kima. Indonesia is Tridacnidae's most varied and...

Just to share a little beauty this evening. Delving ever further into the marine treasures of Indonesia I have received this among a small lot of Cassis Cornuta pearls today.

In a recent discussion with Douglas of Cortez Pearls mineral oil came up as a great means of cleaning and refreshing the luster of pearls. In his case, removing the extrapallial haze of newly-harvested pearls, as well as keeping and restoring older pearls to their highest luster. Seems to me...

A circular received today from the Swiss Gemmological Institute that appears to be quite a bit more than routine. This follows an interesting lead-in article on Micro X-Ray tomography (CT Scanning) in SSEF's January Facette. LINK to SSEF Newsletter updated May 12 (click 'Trade Alert' at bottom...

It's been a Pearl Summer… The Saturday night reception at Pearl Paradise during ICPGC (International, Consequential Pearl-Guide Conference) last month offered pearl-viewing opportunities galore, as expected. Unexpected was the attendance of Jeremy Norris, natural pearl hunter extraordinaire...

This thread requires some review, and I propose to start with this post in the Pinctada Maculata thread concerning our necklace 'Poe Io Mata Nui' by Ben Bergman in Rarotonga. Trepidation abounds in starting this thread (when has that stopped me before?), as it portends a culmination of sorts. I...

While I have grudgingly accepted the fact that conch pearls are the exclusive playthings of the filthy rich with their unmentionable offshore accounts in the Caribbean, occasionally the beauty is so astounding that almost any price seems worth paying. The attached pearl, currently the object...

This thread continues a personal voyage, trusting that others are traveling similar roads and will also share their experiences. In Natural Combinations my interests in poe pipi from the Cook Islands and paua pearls from New Zealand were bridged, resulting in the natural pearl pin that serves...

Today very good friends came to spend a sunny Sunday with us in the mountains, and she wore the choker below, one of her less formal pieces (pearls in the 6mm range). It was purchased by her husband on a working trip to Tokyo in the 1970s. He had gone to Victor's Pearls, having been forewarned...

A recurring lament among forum members is having spent a bit more on our pearl addiction than intended. Nonetheless, we’ve no doubt all regretted not having pulled the trigger on occasion. On a slow pearl day I was reviewing past communications and came up with my own example, below. Any others...

An appointment reminder received today from the same dentist who said: Anyway, here is a thread for dumping anything else of dubious value otherwise tastefully hidden.

This is posted under 'Pearl History' and not 'Pearl Fashion' for apparent reasons. On another thread I mentioned that we had been in Miami last week, attending a major wine and food event featuring Spain that scored the major coup of an official visit from King Juan Carlos and Queen Sofia. We...

This thread follows travel (ostentatiously for business) referenced in the Pinctada Maculata thread. Following our meetings in Wellington we drove five hours up the wild west coast of New Zealand’s North Island to the surfside village of Oakura in the shadow of Mount Taranaki (Mt. Egmont), New...

Just back from a wonderful week on New Zealand's North Island, driving from Wellington to Auckland with business in both cities and plenty of fabulous places to see in between. Saw some strands in passing that I thought well worth noting: Photo on left: Window display on Lambton Quay in...
