Born in Port Washington, New York in 1939, she studied art at Boston University; Art Students League, New York and Institute Allende, Mexico. Her works were exhibited through out the U.S. and Mexico, including the El Paso Museum of Art, Galleria San Miguel de Allende, Mexico and National Society of Painters in Casein, New York. Her mediums were etchings, watercolors, casein tempera paintings, lithographs and drypoints and were typified by delicate colors and imaginative characterizations.

She devoted many hours of painstaking research to each image, drawing upon a wide variety of sources, including medieval book illuminations and sculpture, Roman frescoes, the Bible, astrology, Oriental philosophies and American and English literature. The resulting imagery had intense symbolism that belied its simplicity. Her works encompassed a variety of subjects, including the mythological character Pegasus, creatures from a medieval bestiary, and the story of Moses.

Between 1975 and 1979, Jablonsky devoted herself to a project based on the theme of the Garden of Eden. Her involvement in creating different images on this subject was so intense that she said, "...real time seems to have no relationship to working time." Her efforts resulted in 22 watercolors, 25 casein tempera paintings and a portfolio of 11 original lithographs elucidating her interpretation of Eden.

Later, she focused her talents on her favorite authors, a perfect subject for a person who described herself as "an incurable reader." The "Authors" portfolio of original embossed drypoints captured the character and imagery of each writer through the use of a personal symbol which each held. According to the artist, "...the 'Authors' as I represent them are children holding toys-their symbols, obsessions and dreams."
