As a name, Topaz is sophisticated and sultry; as a golden gem, it's said to have healing and energizing properties and also to bring good luck-- and being the birthstone for November could make it perfect for a baby born in that month, with that final 'z' giving it some extra sizzle.
The topaz gets its name via French and Latin from Greek; it is probably ultimately of oriental origin.
There is an eponymous novel by Leon Uris--later made into a 1969 Hitchcock movie--in which Topaz was the name not of a person but a spy code name, and in the Dodie Smith novel I Capture the Castle, there is a character named Topaz Mortmain.
