It is interesting to look for connections among the various symbols.

Númenor of course was a five-pointed star shape, and the Star of the House of Fëanor is described by Gandalf on the Moria West-gate as only having 'many rays'. The illustration seems to show sixteen.

We also see seven Lords of the Valar and seven Queens.

The Crown of Durin certainly has seven stars, which would seem to correlate with the Seven Fathers of the Dwarves. Aulë the Vala 'made' the Dwarves with Eru's blessing, and so attains the Seven connection that way, maybe?

The Silmarillion in Of the Beginning of Days states the Trees both took seven hours to fully wax and wane.

Seven has the Christian significance of being the 'perfect' number; ie the Days of Creation, and in the West of the world today is still considered lucky. I'd be very tempted to say that factored into Tolkien's repeated use of the number.
