- A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.ridium is one of the rarest elements in Earth's crust, with annual production and consumption of only three tonnes. 191 Ir and 193 Ir are the only two naturally occurring isotopes of iridium, as well as the only stable isotopes; the latter is the more abundant of the two.

- Because of their crystal structure, only the star sapphire and the star ruby show six white rays of light that meet in one point and dance over the gem's surface when viewed from different directions. Star sapphires range in color from blue in various tones, pink, orange, yellow, green, lavender and gray to black. The most desirable color is a vivid, intense blue. Star sapphire is a durable, popular stone for men's rings. A black star sapphire supports a masculine image best. In ancient times, star sapphire was regarded as a powerful talisman guiding travelers and seekers of all kinds.

Why does mila kunis have amazing eyes?  (what is heterochromia iridium?) What causes the difference in color? This is caused by a medical condition called “Heterochromia Iridium” (Heh-ter-row-krow-me-uh Ih-rid-ee-um). Hetero-means other or different while-chromia is related to color, so when the two are put together it means that the irises of someone are two different colors.

Iridium Iridium is the most corrosion-resistant material known. It is used in special alloys and forms an alloy with osmium, which is used for pen tips and compass bearings. It was used in making the standard metre bar, which is an alloy of 90% platinum and 10% iridium.

Rubidium Rubidium has also been reported to ignite spontaneously in air. Rubidium has a very low ionization energy of only 406 kJ/mol. Rubidium and potassium show a very similar purple color in the flame test, which makes spectroscopy methods necessary to distinguish the two elements.ubidium has also been reported to ignite spontaneously in air.

Chrysoberyl Alexandrite, a strongly pleochroic (trichroic) gem, will exhibit emerald green, red and orange-yellow colors depending on viewing direction in partially polarised light. However, its most distinctive property is that it also changes color in artificial (tungsten/halogen) light compared to daylight.tones that show a dramatic color change and strong colors (e.g. red-to-green) are rare and sought-after, but stones that show less distinct colors (e.g. yellowish green changing to brownish yellow) may also be considered alexandrite by gem labs such as the Gemological Institute of America.

- An iridium ring is a piece of jewelry that is made out of the precious metal iridium and worn around the finger. Iridium is one of the platinum metals. It's rare and expensive because it's the most corrosion-resistant metal on the planet and is far harder to melt than gold.

- We use the term pine cone to describe any cone from any conifer, but that's not right. Evergreens come in many types: spruce, fir, pine, hemlock, cedar. They are all called conifers because they all bear cones. We should name the cones for the parent trees – spruce cones, balsam fir cones and so on.

What Is Pyridium (Phenazopyridine)? Pyridium Warnings. Do not take this medication if you are allergic to Pyridium or if you have kidney disease, liver disease, or any other blood disorder. Pyridium will cause your urine to be dark or turn it to an orange or red color. This is a normal effect and is not cause for alarm.

Iridium: the essentials Iridium is white, similar to platinum, but with a slight yellowish cast. It is very hard and brittle, making it very hard to machine, form, or work. It is the most corrosion resistant metal known, and was used in making the standard metre bar of Paris, which is a 90% platinum-10% iridium alloy.ridium has no biological role. Iridium is found as the free element alloyed with platinum and other platinum metals. Naturally occurring alloys include osmiridium and iridiosmium, both mixtures of iridium and osmium.

IRIDIUM (REVISED) The periodic table is a chart that shows how elements are related to one another. Indium is a transition metal that is also part of the platinum family. The metals in the platinum family are also known as the noble metals. They have this name because they do not react well with other elements and compounds. They appear to be too superior to react with most other substances. In fact, iridium is the most corrosion-resistant metal known.

Iridium A member of the platinum group metals, iridium is white, resembling platinum, but with a slight yellowish cast. Because of its hardness, brittleness, and very high melting point, solid iridium is difficult to machine, form, or work, thus powder metallurgy is commonly employed, instead.he discovery of iridium is intertwined with that of platinum and the other metals of the platinum group. Native platinum used by ancient Ethiopians and by South American cultures always contained a small amount of the other platinum group metals, including iridium.

Eye health guide Heterochromia iridium, or segmental heterochromia, is different, it occurs when areas, or segments, of the same eye are different colours. Image courtesy of Wikimedia Commons. What causes heterochromia iridis? The pigment melanin is responsible for the colour - or pigmentation - of our eyes. Heterochromia iridis is caused by too much or too little melanin. This can be due to inherited genes or a problem that occurred when the eyes were being formed.
