Hema (हेमा) is the Sanskrit word for "gold" — also from hima (snow, as in Himalaya). An epithet of Parvati and Lakshmi.
Hema Malini (born 1948) is the "Dream Girl" of Bollywood — legendary actress and politician.
Hema does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Hema reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
