Dimant Riva Lazarevna (née Levius) (born 8 December 1925, Riga) – cashier and clerical worker.

Riva Dimant received an incomplete secondary education at Secondary School No. 13 in Riga. In 1945, she graduated from Vocational School No. 9 with a qualification as an electrician. In Riga, she held positions as a clerk, cashier, secretary, typist, and technical editor.

In 1941, she was evacuated to Kirov Region with her mother, Frida Levius (1895–1950), and her brothers. Her brothers were conscripted into the army. Feitel Levius (1921–1940) and Yehuda Levius (1923–1940) were killed in the Second World War. Mikhail Levius (born 1920), a war invalid, returned to Riga. In 1951, Riva married Rakhmiel Dimant (born 1927), though the marriage was dissolved shortly before her emigration with their son, Lazar (born 1953), to Israel in the 1970s. In 1974, her former husband joined the family in their historical homeland.
