    DIY Project: Make your very own Pearls in Half!

    You have probably seen those photos of beautiful pearls that have been "cut in half" so you can see their inner structure, and you probably wondered how those are worked: are they sawed off? maybe a machete?


    Well, wonder no more! This little video explains in detail how you can make your very own, very nice...pearls in half.

    You will need:
    1. Sandpaper sheets, one of each: 60 (very rough), 80 (medium grit) and 220 (fine grit, also called "water

    Pearls in the Web of Life - Part 2

    In a sense, pearl oysters might be a “small ecosystem” of their own, a self-contained biome where a tug of war ensues and leads to eventual stability. But why does this happen? And does it hurt the mollusk? One of my Marine Biology teachers -Dr Fernando Manrique, a friend of Jacques Cousteau- once told us that the Ocean was teeming with Life, and that the hardest thing for many lifeforms to find was an “available apartment”, a place to settle and that would help them avoid being tossed...

  • Mabe Pearl Grading - 7) Dome Height

    Mabe Pearl Grading - 7) Dome Height

    Part of the beauty of a Mabe pearl comes from its “dome” (height). When a Mabe pearl displays a low dome it most closely resembles a piece of mother-of-pearl shell than an actual pearl. Unfortunately, many Mabe pearls today are grown too flat, due to the intrinsic characteristic of the host shell: Pinctada shells are usually flatter than Pteria shells (the shells being much more concave) which does not allow for the use of tall implants, since these will touch the opposite shell and will cause the...

    Mabe Pearl Grading - 6) Nacre Quality

    The most important factor here is nacre thickness. Many Mabe are cultured for short periods of time (4 months) to obtain the most perfect shape, but at the expense of their nacre thickness and durability. On the other hand, there are producers that grown them for too long (over 12 months) and end up having pearls that have thick nacre, but their shapes are not standardized, and they may display one or more of the surface imperfections we discussed in the previous paragraph. There is usually a middle...

  • Grading Mabe Pearls -5) Surface Quality

    Grading Mabe Pearls -5) Surface Quality

    As with other pearls, surface quality is an important attribute: the cleaner the surface is, the more desirable the Mabe is and more valuable too. The usual surface imperfections found in these are:

    • Missing Nacre: whitish, bite shaped marks.
    • Spots, pinpricks: dark or light-colored pin-prick markings.
    • Rippled surface: these are markings caused by the growth of the abductor muscle on top of the blister pearl. This marking causes the appearance of wavy...

  • Grading Mabe Pearls - 4) Mabe Luster

    Grading Mabe Pearls - 4) Mabe Luster

    Mabe pearls are not very known for their great luster, although many of these pearls may display amazing luster. Mabe usually display a more silky or subdued luster, especially in the Pinctada species and is most shiny in the Pteria species…but luster is usually enhanced by means of a final polishing, done with a high-speed cloth-wheel and a polishing compound, although much care must be taken to avoid excessive polishing that leads to heat and may ultimately damage the pearls by “burning”...

  • Grading Mabe Pearls - 3) Colors

    Grading Mabe Pearls - 3) Colors

    Mabe pearl color is highly dependent on the species of mollusk that is producing the blisters, and even within each species you will be able to find a great variation of all-natural colors, but many Mabe are also dyed to produce an artificial coloration. Although we will not go in great detail on this subject, we will quickly cover some of the ways these pearls are given these artificial colors.

    We have already covered the different natural colorations we can find in the different species...

  • Grading Mabe Pearls - 2) Mabe Shapes

    Grading Mabe Pearls - 2) Mabe Shapes

    Mabe pearls can have any shape desired, as long as you attach it to the mollusk’s shell. Some cultured pearls have done this same thing, especially some freshwater pearls that have used faceted mother-of-pearl beads to produce so called “diamond pearls”, or star- and even shuriken- shaped pearls, but in the case of Mabe pearls it is even much varied and you can find hearts, stars, teardrops, ovals, crosses, and basically, any other possible combination you can think of as long...

  • Grading Mabe Pearls

    Grading Mabe Pearls

    VII. Grading Mabe Pearls

    Mabe pearls can be graded using most of the same grading standards that we have already seen for the traditional cultured pearl:
    1. Size
    2. Shapes
    3. Color
    4. Luster
    5. Surface Quality
    6. Nacre Quality
    But we can add an additional one that is quite important for this variety of pearl:
    7. Dome Height

    Even so, many of these value factors are not as employed as strictly as they are with regular cultured pearls, but may actually be quite lax, and if...

    The Sustainability Corner - Part 3

    Pearls in the Web of Life – Part 1

    Pearls are not only a product of a living being -a mollusk- but their “mother mollusk” is also a host for dozens of other life-forms! When we think about other animals that we use in our lives (as a food source or as a luxury good, such as furs) we can rarely imagine these creatures being a part of something larger or co-existing with other animals from different species. We may picture a henhouse bursting with chickens, or a pen full...
