The element that gives emeralds their beautiful green color is the same element that turns corundum into red rubies - chromium.

A star produces atoms in nuclear atomic chemical fusion or fission reactions.\nThe lifetime of a star takes fusion:\n3x4He > 12 C\n4 He + 12 C > 16 O plus 2x12 C > 20 Ne + 4 He\n56 Fe = Iron\n(4 He + 12 C = 16 O)+(2x12 C = 20 Ne + 4 He)_20 Ne + 4 He + 2x16 O\n= 56 Fe\nAs Iron consists to the sun's sunspots now for a magnetic field or liquid Iron of 5,000*C this gives the impression it is black against an even more hot and brighter gassy nuclear background.\nBut when the sun begins too end it's life the fusion reaches oxygen and then reaches Iron (Fe) and Beryllium (Be).\nAs the sun is completely filled with Be and Fe at the core. As metal absorbs energy and nuclear and gas forces out then the absorb from the metal core and as energy is released from the outer layers the star is unstable and is formed as a variable. The outer layers are swapped with the inners and the new outer layers are pushed off and out to a red giant until the core revs and the red giant keeps size for a while until a new process begins and the new inner layers of Oxygen from the old outer layers and the Oxygen keeps the red giant pushed out to size and then the whole star is cast as gas/plasma Iron and the star's power, heat and energy accelerates the star and with Oxygen inside, the explosion is created and a new atom is created, Gold.\nThe minerals create stars from 116 elementary chemicals.\nThe stars are made in the nebulae and new stars are made and so are planets. Thus the planets and stars create life from their chemicals and their chemicals come from the supernova.

RED ... the color of passion. A very uplifting color.  Gives you energy.

Krypton is a chemical element with the symbol Kr and atomic number 36. A colorless noble gas, krypton occurs in trace amounts in the atmosphere, is isolated by fractionating liquefied air, and is often used with other rare gases in fluorescent lamps. Krypton is inert for most practical purposes but it is known to form compounds with fluorine. Krypton can also form clathrates with water when atoms of it are trapped in a lattice of the water molecules.

Woah I just answered this question. Weird. The 15 year gift is Crystal. As in, wine glasses, etc. For gemstones its Ruby.

It's an iron oxide and it forms in an oxidising environment. Rich deposits may be the result of weathering, or precipitation out of oxygen-rich surface water or oxygen-rich water in hydrothermal veins.\n\nAs to why it is sometimes red and sometimes metallic-grey I'd say it is probably due to the size of the crystals. When it is ground up fine, it is always red. The smaller grains scatter red light.

It is possible to grow crystals that are naturally red.  You grow them from potassium ferricyanide (not the same as cyanide).  \n\nThese links have more information about red crystals.  I hope this helps.

The main color of the martian soil is due to the presence of limonite, a mixture of hydrated iron oxide minerals like geothite (FeO(OH)). It might also contain some red hematite Fe2O3, which is the main ingredient of rust on earth. The soil might also contain about 1% magnetite, Fe3O4. \n\n\nThere appears to be some substantial grey hematite deposits on Mars. The Mars Surveyer saw evidence of it using infrared imaging in 1998 at the Martian equator, near a place called  Sinus Meridian. It is like the red hematite we know here on earth except it has a different crystal structure. It is interesting because it strongly suggests the existence at one time of water on Mars. \n\nLimonite:\n\nAny of a group of widely occurring yellowish-brown to black iron oxide minerals, essentially FeO(OH)·nH2O, used as a minor ore of iron.\n\nHematite:\n\nA black or blackish-red to brick-red mineral, essentially Fe2O3, the chief ore of iron.\n\nMagnetite:\n\nThe mineral form of black iron oxide, Fe3O4.

One way is to plate metal as a substitute for chromium. Rhodium is often referred to as hard chrome.

The red color is found in many soils around the world.\nThe cause of that is the presence of oxides and hydroxides of Fe and Al.\nThose soils are known as ''weatherized'', usually done by many, many years of exposure to heat and humidity.

I would have to say, Red

Carmot\nFrom Wikipedia, the free encyclopedia\n\nThe "element" Carmot was a sort of element no longer believed to exist according to modern scientific knowledge. In history, carmot was the element most alchemists believed to be the key component in the creation of the much sought-after Philosopher's Stone. It was also thought to have had a dark red tone.\n\nFor any other answers, I suggest you check here:\nhttp://www.google.com/search?hl=en&q=Carmot

Several, but, the answer you seek is likely Iridium.

Purely an opinion on my part, but..\nHydrogen - because it is the most abundant element and is a component of water ( the universal solvent)\nOxygen, because it is also a componant of water and is key to redox reactions\nCarbon - because it exists in many different states coal graphite diamond\n\nThe next two are more difficult, but I offer up Iron, because it is the last element able to be produced by a star without going Nova\n\nand Gold - for obvious reasons\n\n\nConsidering Chemical reactions, I would change in favor of Flourine, Sodium, Oxygen, Chlorine and Hydrogen
