Answer 1

Mmm youl need to tell us if you want a element or a mixture....

And a natural element or a lab created one...

As far as I know promethium is the rarest element that doesn`t exist in a natural state on earth....

While natural elemnt will be polonium, astatine, francium, radium, actinium and protactinium.....

And lab/non-existent will be antimatter :) or dark matter

The are making antimatter at CERN

and dark matter we only have theories and proof that it atracts other material but no clue what it is

Answer 4

Jadeite, it prob is the rarest gem in the earth.

Until recent years jadeite has been something of a mystery mineral, but we now know of primary sources in Guatemala as well as several California occurrences of white or grayish jadeite. Boulders in which a few small freestanding crystals have been seen occur in San Benito Co., California, with additional finds in Clear Creek, between New Idria and Hernandez. All Mexican jadeite is in artifacts, from unknown sources. The record price for a single piece of jadeite jewelry was set at the November 1997 Christie’s Hong Kong sale: Lot 1843, the “Doubly Fortunate” necklace of 27 approximately .5 mm jadeite beads sold for US$9.3 million

this prob will help....=]

Rare earth elements and rare earth metals are a collection of sixteen chemical elements in the periodic table, namely scandium, yttrium, and fourteen of the fifteen lanthanoids (excluding promethium), which naturally occur on the Earth.
