What's strong enough to smash ships but still fears the sun?

A title for crabs and cakes alike. My crowning achievements are a God-given right. I'm half of a castle and two times a twin. Fisher and Burger are just two of my kin.

I shimmer beyond your night-lit skies A chained princess where starlight lies Not a goddess yet named the same A spiral sea of cosmic flame. What am I?

In the heart of blooms, a golden elixir flows, a sweet alchemy sought by winged travelers, ancient ambrosia of the sun's embrace, whispering tales of vibrant life.

I sprout from a head, but I'm not a horn. Some will try to collect me, their wall to adorn. Mostly worn my males, it's true. But there are cases where females have me too.
