  • Provoked Baroques

    Provoked Baroques

    Provoked Baroque, a term coined by Doug Fiske, aptly describes the newest type of Tahitian pearls. It is now possible to skip the long wait for large pearls that grow in later grafts, while keeping the color and luster that typify earlier, smaller pearls.


    Many of these pearls exhibit folds that make one think of the chocolate candies "Raisinettes", but these treats have baroque shell nuclei inside.

    The technique was published in "The Australian Gemmologist...

    Welcome To Pearl Guide News!

    Welcome! Pearls have long been a subject of fascination ? beautiful gems produced by living organisms, with or without the help of human intervention. In the early 20th century, cultivation of pearls brought regal beauty to the masses. More recently, improvements in techniques, advances in cross-breeding, and fervent experimentation have redefined our expectations of what a pearl should look like, and even be. The Pearl-Guide.com forum has been the home of lively discussion on every con...

  • The State of Today's Cultured Pearls

    The State of Today's Cultured Pearls

    All perfectly spherical. All luminous. All highly lustrous.

    Two are Hanadama-grade akoya cultured pearl strands, and one is a solid-nacre freshwater cultured pearl strand. Surprised? The time has come for the best of freshwater cultured pearls to be recognized as reaching the same level as saltwater cultured pearls. Prices are rising in response to the vast improvement in freshwater quality, and freshwater pearls have something that saltwater pearls don?t ? endless variety. ...

  • Burmese Triple Threat

    Burmese Triple Threat

    The AGTA Tucson show is filled with fabulous gems that compete for attention, but this necklace stopped everyone in their tracks.

    Painstakingly collected for twelve years, starting in the 1960s, this triple strand necklace of natural-color pale pink cultured Burmese pearls is virtually priceless. Fran Mastoloni says ?The pink color was a little more prevalent in the early days of Burma. Lately, however, the colors are more champagne to cream.? ...

  • Pearl Quality

    Measuring Pearl Quality

    Pearl quality and thus, the value of a pearl is measured according to a combination of several varied factors are: the type of pearl, the thickness of its nacre, its luster, the cleanliness and texture of its surface, its shape, its color, and its size. Because the pearl is a naturally occurring organic gemstone, created by living creatures, these factors can and do vary widely. Although all of them affect the ultimate value of a given pearl, some of the facto...

    Pearl Sizes

    Pearl Size Is Measured in Millimeters

    A pearl's size is measured according to its diameter in millimeters. Sizes range from 1 millimeter or less, in the case of very tiny pearls, to as much as 20 millimeters (more than 3/4") for large South Sea pearls.

    The Average Pearl Size Today is 7 Millimeters Most pearls sold today, however, are in the 7.0 to 7.5-millimeter range. Akoya pearls greater than 8 millimeters are considered extremely rare. (The largest pearl an akoya oy...

  • Pearl Shapes

    Pearl Shapes Vary Widely

    Because pearls are natural organic gems created by a myriad of living organisms, they occur in a wide variety of shapes, many of which are quite unique and interesting. Also, cultured pearls tend to be rounder than natural pearls because (saltwater) cultured pearls usually have a bead inside that will help guide the shape.

    Some shapes are distinctively unique to certain species of mollusks, as is the case in Abalones (Haliotis spp) that commonly...

  • Pearl Surface

    Pearl Surface in Pearl Grading

    The surface cleanliness of a cultured or natural pearl has a direct correlation to its value. A pearl can never, according to rules set forth by the FTC, be graded as "flawless", but the degree or percentage of inclusions or surface imperfections can be measured by anyone with experience.

    What to Look for on a Pearl's Surface When grading pearls, the appearance of the surface of a pearl is one of the most important characteristics in determin...

    The arrival of the Iberian Conquerors

    The Native Nations had no real interest in establishing a commercial venture in pearl fishing and we understand little to nothing of the way they fished for pearls, since most of the information was either lost or destroyed during the conquest of Mexico. The rich plunder of the Conquistadores was sent to Spain and later dispersed all over Europe. The most significant information we have on the subject comes from the period of colonization of northwestern...

    by CortezPearls
    Hello dear Pearl-Guide.com Forum Members: With spring comes renewed energies and pulses, the recent system upgrade also allows me to start adding up content that we believe is necessary to keep the forum growing and renewed, making it the #1 Source for Pearl information on the World-Wide-Web for years to come. I had this idea of a column years ago, when I still published "The Sea of Cortez Peal Blog", which went "black" after a massive Russian hacker attack (the importance of updating your system...

  • JIV's April webinar spotlights industry's new movers and shakers
    by CortezPearls


    A new generation of jewellery and gemstone professionals, more diverse geographically and culturally from the generations that preceded it, is poised to transform the trade. This is in no small part because the composition of its members more precisely mirrors the consumers who both buy and aspire to buy fine jewellery products.

    What characterizes many in this peer group is that they are first generation jewellers, who chose to join the industry not through family legacy,...

    By Douglas McLaurin-Moreno


    Since unrecorded time, man has obtained many bounties from the world’s oceans: food, shells, corals, sponges, seaweeds, and the most desirable of all of these were the beautiful mother-pf-pearl shells and their valuable treasure, Pearls.

    Mexico has four species of pearl oysters inhabiting its coasts, two -the larger sized- on the Pacific side: the Panamic Black Lip...
