Mutya is the Tagalog word for "pearl," "muse," or "precious treasure." Used as a title of honor for a beloved daughter or beauty queen.
Mutya Buena (born 1985) is the British Sugababes singer of Filipino heritage.
Mutya 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 Mutya reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
