Today, the Queen of England owns jewels cumulatively worth somewhere around $80 million. These are not solely the classic stones (emeralds, rubies,
sapphires, and
diamonds) either; there are plenty of other
gems which carry rare beauty and stunning
brilliance, enough to rival a 2 1 2
carat diamond ring.
Painite
A dark red
gemstone displaying varied hues of
color based on the angle of viewing, painite is one of the rarest and costliest minerals on the Earth. Suffice to say, it does not come cheap. Its composition is mainly zirconium, calcium, aluminum, boron, vanadium, and chromium.
Bixbite
Known as Red Beryl, Bixbite is actually a black
colored oxide mineral. Its name derives from Maynard Bixby, who first discovered it.
Serendibite
Serendibite is only found in Sri Lanka and has an opaque appearance as well as
green, blue, and golden brown pleochroism under diffused light. A
carat of this
stone can cost around $15,000. Its composition is magnesium, calcium, iron, aluminum, silicon, and boron.
