Day 3

Demonstrating the method of cultivation

Mid-morning we gathered to walk to the Pearl Farm for our 10am tour. Douglas, one of the owners, gave a fascinating and comprehensive talk on pearl farming in the Sea of Cortez.

They took a scientific approach to find a method of cultivation that has a low mortality rate. The pearl oyster larvae attach themselves to artificial corals for protection.

After a few months the juveniles are collected by hand and transferred to “oyster condominiums” where they feed and mature.

When large enough, they are carefully inoculated with a mother of pearl seed. Donor tissue from the mantle of a “rainbow” oyster is transplanted next to the seed. The goal is the production of rare colors in the pearls.

The pearls grow in size for four years adding a thick, rich coating to the seed pearl. This results in a valuable, durable pearl with a beautiful iridescent sheen.

Their method has had beneficial impact on the local marine environment, many more pearl oysters are growing naturally in this protected enviornment.

Everyone really enjoyed his presentation, and several guests bought pieces of jewelry.

People spent the afternoon exploring town, reading, and visiting the beach.  We held a drivers’ meeting to get ready for the next day's travel, followed by snacks and margaritas. Another lovely day in paradise!
