PICTURE THE Aztec calendar stone in three-dimensional detail, except it's made of 5 pounds of solid bittersweet chocolate, is more than a foot in diameter and gleams with an edible bronze luster. How about a row of inch-high chocolate laughing Buddhas, their plump bellies stuffed with tamarind and mango-flavored vegan chocolate ganache? Would you bliss out on Chakralates - seven bonbons filled with organic herb and fruit ganache to correspond with the seven chakras of the body? Naturally each is a different flavor such as black currant, cherry/hibiscus, cardamom and candied ginger.

These are some of the esoteric treats dreamed up by San Rafael residents Malena Lopez-Maggi, 25, and her domestic partner Clive Brown, 53. The budding chocolate artisans call their business The Xocolate Bar -pronounced "shocolate" and spelled after the Aztec word for chocolate, xocolatl. They founded their company in 2006.

"We've done a lot of experimenting," Lopez-Maggi says. They showed their line of chocolates at the KPFA Craft Fair in December and two weeks ago at San Francisco's first International Chocolate Salon at Fort Mason, at which it won a number of tasting awards, including gold mentions (the top category) for best in salon and best gift

set; silver for most delicious ingredient combination and most gifted chocolatier 2007, and bronze for most artistic chocolate design.

"It was really our first big-time exposure," says Lopez-Maggi. "I can't believe how well we did. We were total newbies."

Brown, a chef and jewelry designer, and Lopez-Maggi met on craigslist. Both partners claim to love chocolate and love making things with their hands. Combining the two interests to become chocolatiers seemed a natural progression. And though Lopez-Maggi took a brief course in industrial-style commercial chocolate making at the University of California at Davis, they consider themselves self-taught artisan confectioners.

"Clive and I experiment a lot," Lopez-Maggi says. We constantly tweak our recipes to make a better, more gourmet product."

The couple cook up their treats in the Presidio Yacht Club's kitchen in Sausalito. Most of their sales are online, although Lopez-Maggi says she has high hopes for the company's debut at this weekend's International Gift Show at San Francisco's Moscone Center.

She takes pride in their hands-on approach. They blend their own couverture from some of the higher-end chocolates on the market, such as Valhrona, E. Guittard and El Rey. They use chocolates made from fair-trade harvested beans. Their ganaches are made from all-organic ingredients such as Straus cream and butter, or agave syrup in their vegan stylings. Most of the chocolates are dark, with 70 percent cocoa butter content. The couple produces more than 17 pieces.

I love the flavors, and get a kick out of the duo's imaginative designs - including a 5-inch-high solid chocolate version of the Venus of Willendorf, a 22,000 year-old primitive sculpture of a round, brown-skinned earth-mother. How appropriate.
