A review: The History of Pearls in the Gulf of California, Mexico - PART 1

A review: The History of Pearls in the Gulf of California, Mexico
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 oyster (Pinctada mazatlanica) and the Rainbow Lip oyster (Pteria sterna). On the Gulf of Mexico and Caribbean Sea we can find the smaller Mother-of-pearl oyster (Pinctada imbricata) and Atlantic Winged oyster (Pteria colymbus). There are many other pearls occurring in Mexico, such as conch pearls (Lobatus=Strombus gigas), pen shell pearls (several species of the Pinna and Atrina genus), scallops (genus Nodipecten and Spondylus) and Abalone (several species of Haliotis), as well as from many more species of clams and gastropods, but pearl oysters of the Pteriidae family will be the sole focus of this document.

Pre-Columbian Period
In Mexico, the native pearl fisheries can be dated as far back as 500 to 1400 C.E. Fishing was practiced by many native tribes of the States that surround the Gulf of California and Mexico’s Pacific coast such as the Seri (or Kuum Kaak), Yoheme (Yaqui and Mayo) and Pericú Indian Nations. These ancient pearl fisheries were undertaken out of hunger, fortunate byproducts being the recovery of shells and pearls.

Excavations completed inside Tenochtitlan’s (today, Mexico City) Main Temple (Templo Mayor) of the Mexica or Aztec empire revealed the high appreciation that this culture had for the mother of pearl shells from the Pacific Ocean. These shells were used either as a whole or as pectorals, or in carved zoomorphic figurines that the Aztecs used in their religious rituals.

The Maya from the Yucatán Peninsula also employed pearls and nacreous shells for the same purposes, one of the most distinguished items that we can find from their culture is the funeral mask of King Pakal the Great (603 –683 C.E.), an elaborate mask made from 340 pieces of jade, with the eyes made from mother-of-pearl and obsidian discs, the earlobes adorned with two massive baroque pearls.

Over 3 thousand pearls were found at this site, some quite large and all from the Panamic Black Lip oyster (Pinctada mazatlanica). Photo taken at the Museo de las Culturas de Oaxaca Santo Domingo in Oaxaca City.
