I can give a first-hand report that the harvest is just about done and seems to be going well. I was down in Guaymas scuba diving with a friend last week, and had the privilege of visiting the farm and meeting Douglas in person. What a sweetheart!...but I digress...
The farm is located on the premises of what used to be a university (where Douglas and his two partners did their studies in 1993, deciding to try farming pearls instead of clams or other food-based aquaculture). The farm has been in this same location since then, with the same partners still working together, though the educational facility is now a high school. I'm assuming it's more populated when school is in session, but when I visited only the pearl farm workers seemed to be there.
From my hands-on experience at Kamoka, I had a good idea of the general workings of pearl production, and the Cortez pearls are produced in pretty much the same way. Rather than join a group tour (a couple groups came through while I was there, mostly high-school-aged kids from Mexico), I had the opportunity to ask Douglas all of my questions directly. These oysters are much smaller than the ones used to produce Tahitian pearls, with a shorter lifespan. Accordingly, they are only grafted once before being harvested. The annual production is approximately 3000 full pearls and 5000 mabes. Nothing goes to waste; when the pearls are harvested, the oyster meat is removed and cleaned, and the shells are subsequently processed into mother-of-pearl for local artisans and also used to back the Cortez mabes.
The full pearls are produced after the oyster has been in the water two years after grafting; the mabes are in the water for 18 months. Accordingly, the nacre is quite thick and durable. Douglas showed me the cross-section of a full pearl, and I was surprised to see almost 2mm of nacre around a 8mm nucleus. All of the colors are completely natural, and quite beautiful. Lots of watery iridescence I've only seen in this type of pearl. I brought a nice stash home, including some mabes with the most amazing coloration I've ever seen in a real pearl. Smooth shiny rainbow metallics. I'll try to post some photos soon. Alas, the camera I had with me got flooded when I went diving with the sea lions the next day, wiping out all of my photos, but I know you REALLY want to see the pearls...
Now a few nuts and bolts if any of you are thinking of making a trip down to visit Guaymas yourself. First and foremost, it's HOT in the summer, and apparently last week was quite cool compared to what the upcoming months will bring. I stayed in San Carlos, the more "touristy" town next to Guaymas, and the main activities seem to be fishing and diving. There are a couple of nice gift shops, and a handful of restaurants, but it's definitely not a hotspot of tourism. You can get to the pearl farm by bus - cheap and easy.
Guaymas itself is more a city for locals, though cruise ships also sometimes stop there, and there are some beautiful old buildings. The whole region has clearly been affected by reports of crime and the flu, not to mention the occasional tropical storm. My friend and I had the boat to ourselves on each of the 4 days we went diving. As far as crime, I have never felt so safe anywhere in Mexico as I did in San Carlos. People were friendly and helpful, the town was clean, and the local seafood was divine. The margaritas were quite tasty, too!
Sorry for the lack of photos, but pearl pictures will be forthcoming.
