Golnar is from the Persian گلنار (Gol-nār — gol flower + nār pomegranate / fire) — pomegranate flower, fire-flower. Golnar is one of the Persian feminine names — central to traditional Persian poetic + Zoroastrian + Islamic heritage. The pomegranate (anar) is central to Persian + Iranian floral symbolism Shab-e Yalda (winter solstice festival 5,000+ years old) where pomegranates symbolize the sun's rebirth.
Golnar 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 Golnar reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
