Red corals are ideally suited to investigate several key questions of Iron Age research, like trade patterns or social and economic structures. While it is fairly easy to distinguish modern C.
  • Pearls and Organic Gemstones

    Pearls and Organic Gemstones

    Pearls and Organic Gemstones INTRODUCTION Pearls were probably the first discovered gems of significance. Because they need no cutting or treatment to enhance their beauty and are rare natural occurrences, they have most likely always been highly esteemed. Organic gemstones are anything created by living processes. We have looked at amber in the past, but bone, teeth (such as ivory), and shells all have some value and are used today as gemstones. Pearls in General A pearl is grown by a mollusk (a bivalve such as a clam, oyster, or mussel or snail [single shell = valve]) in response to an irritant. Bivalves (two shelled mollusks) that secrete pearls live in both fresh‐ and saltwater. The irritant in most cases is a parasite (though it could be a grain of sand or other object). The parasite, a worm or other creature, is walled off by a secretion of calcium carbonate and protein. The calcium carbonate is the same as the inorganic material that makes stalactites in caves, and the protein is called conchiolin. The combination of these two substances (calcium carbonate and protein) makes the pearl's nacre (Nacre is also called mother of pearl). The nacre is a lustrous deposit around the irritant and forms concentric layers (overlapping circles). Many concentric layers of nacre build up over a period of a few years creating a pearl. The internal pattern is much like that seen in a jawbreaker. The layers create a sheen or luster that has iridescence and is described as both pearly luster and if colors of the rainbow are present, the pearl's orient.

    An Effective Tool for Taxonomic Identification of Precious Corals in Jewelry

    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 DNA fingerprinting: an effective tool for taxonomic identification of precious corals in jewelry Lendvay, Bertalan ; Cartier, Laurent E ; Gysi, Mario ; Meyer, Joana Beatrice ; Krzemnicki, Michael S ; Kratzer, Adelgunde ; Morf, Nadja V Abstract: Precious coral species have been used to produce jewelry and ornaments since antiquity. Due to the high value and demand for corals, some coral beds have been heavily fished over past centuries. Fishing and international trade regulations were put in place to regulate fishing practices in recent decades. To this date, the control of precious coral exploitation and enforcement of trade rules have been somewhat impaired by the fact that different species of worked coral samples can be extremely difficult to distinguish, even for trained experts. Here, we developed methods to use DNA recovered from precious coral samples worked for jewelry to identify their species. We evaluated purity and quantity of DNA extracted using five different techniques. Then, a minimally invasive sampling protocol was tested, which allowed genetic analysis without compromising the value of the worked coral objects.The best performing DNA extraction technique applies decalcification of the skeletal material with EDTA in the presence of laurylsarcosyl and proteinase, and purification of the DNA with a commercial silica membrane. This method yielded pure DNA in all cases using 100 mg coral material and in over half of the cases when using “quasi non-destructive” sampling with sampled material amounts as low as 2.3 mg. Sequence data of the recovered DNA gave an indication that the range of precious coral species present in the trade is broader than previously anticipated.

    THE ICA | GEMLAB JOURNAL VOLUME 1 ISSUE 3 THE COVER Cover picture – Carving in Coral depicting John Wayne the American actor famous, amongst other roles, for his wild west movies. On display in the Liverino Coral Museum in Torre del Greco EDITOR’S NOTE Dear reader, welcome to the third edition of GAMMA, the Journal of the ICA | GemLab. GAMMA is now a regular feature of ICA | GemLab’s outreach program and is designed to always provide informative gemmological and industry related content, in a form that is easy and enjoyable to digest. In the words of Richa Goyal Sikri (see Covid Conversations inside) "Considering how the 2020 pandemic has effectively brought the world economy to a standstill", clearly things have changed for us all since our last edition was published, in fact it seems that everything has been turned upside down and is quite unrecognisable from the same time in 2019. Luckily Thailand, thus far, has managed to control the spread of the virus very well through a combination of enforced measures and the natural concerns that the Thai people have for family and community as well as the culture of a wai greeting rather than hugging and/or shaking hands. Because of this ICA | GemLab, with safeguards in place, was able to open up for service on 1st May, after locking down for the month of April, and has remained open since then as gradually the whole of Thailand has come out of lockdown. Thailand is now in a situation of near-normality (minus scheduled international flights). Wherever you are in the world we wish all our readers, their families, friends and their countries a speedy exit from this global disaster and a return to a safe and healthy existence.
