I have, in a sense, everlasting life.
My brothers grow old and brittle while I stay ripe.
I am greatly appreciated and adorned with jewels,
and my head has a crown, it's beautiful.
For most of my life I have braved cold, or heat,
but where I am taken it's always warm,
But my fame cannot last.
The jewels are taken off, along with my crown,
and I am shunned until my successor arrives
in one year.
What am i ?
