what are the dimentions is a one carat diamond and what is the color I?

For Color, It starts with D, E, and F.  These will be colorless.  With a color I, you will have some yellow in it, but not noticable to the naked eye.  This is what my wedding diamond is, and I really don't even notice.  The only way you can really tell, is if you hold it next to a D color stone on a white peice of paper.  Only when you get to a K color, then you can start telling that its a little bit yellow.... unless you are a jeweler.  \n\nWIth the Dimentions, it really depends on what cut you have.  A princess or radient cut will look differently than a round or oval cut.  \n\nA good website that will educate you on Cut, Clairty, Color and Carat is the following:  \n\n(There is some interactive slides that will show you how large a diamond is and also the color)

Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light makes it useful for industrial applications and jewelry (the other equally well known allotrope is graphite). Diamonds are specifically renowned as a mineral with superlative physical qualities - they make excellent abrasives because they can only be scratched by other diamonds, which also means they hold a polish extremely well and retain luster. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion.\n\nThe name "diamond" derives from the ancient Greek adamas (αδάμας; "impossible to tame"). They have been treasured as gems since their use as religious icons in India at least 2,500 years ago—and usage in drill bits and engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of improved cutting and polishing techniques, and they are commonly judged by the "four Cs": carat, clarity, color, and cut. Although nearly four times the mass of natural diamonds are produced as synthetic diamond each year, the vast majority of synthetic diamond production remains small, imperfect diamonds suitable only for industrial-grade use, with gem-quality synthetic diamonds only recently becoming available.

1. A diamond is a specific type of crystal form of Carbon (contrary to what some people say and what some have answered:  a diamond was NEVER coal -- the only similarity is that they both contain carbon.)\n2. You cannot "make" a diamond out of a crystal.\n3. You can try to cut a crystal to maybe resemble a cut diamond, but no one would ever confuse the two.\n4. Crystals have certain alignments of the crystal facies along which the crystal will split -- it is along these facies that an expert will "cut" a crystal to get a specific shape.

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

As stated, 24 karat (with a K) gold is pure; 22K gold would be approximately 92% pure, with the remainder being copper and silver.  In this case, karat measure the purity.\n\nDiamonds are weighed by carats (with a C), which is equal to 200 milligrams.  Apart from being pronounced the same, this is a completely different measurement than the one for gold.

That's like asking how long is a piece of rope. Sapphires come in all shapes and sizes and are typically measured in karats just like diamonds or any other precious gemstone.

Diamond is one of the two best known forms (or allotropes) of carbon, whose hardness and high dispersion of light make it useful for industrial applications and jewelry. (The other equally well known allotrope is graphite.) Diamonds are specifically renowned as a mineral with superlative physical qualities — they make excellent abrasives because they can be scratched only by other diamonds, ultrahard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well and retain luster. About 130 million carats (26,000 kg) are mined annually, with a total value of nearly USD $9 billion.\n\nThe name “diamond” derives from the ancient Greek adamas (αδάμας; “invincible”). They have been treasured as gemstones since their use as religious icons in India at least 2,500 years ago—and usage in drill bits and engraving tools also dates to early human history. Popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, and growth in the world economy. They are commonly judged by the “four Cs”: carat, clarity, color, and cut. Although synthetic diamonds are produced each year at nearly four times the amount of natural diamonds, the vast majority of synthetic diamonds produced are small imperfect diamonds suitable only for industrial-grade use.\n\nRoughly 49% of diamonds originate from central and southern Africa, although significant sources of the mineral have been discovered in Canada, India, Russia, Brazil, and Australia. They are generally mined from volcanic pipes, which are deep in the Earth where the high pressure and temperature enables the formation of the crystals. The mining and distribution of natural diamonds are subjects of frequent controversy—such as with concerns over the sale of conflict diamonds by African paramilitary groups. There are also allegations that the De Beers Group misuses its dominance in the industry to control supply and manipulate price via monopolistic practices, although in recent years the company's market share has dropped to below 50%.\n\nA Diamond is a transparent crystal of pure carbon consisting of tetrahedrally bonded carbon atoms. Humans have been able to adapt diamonds for many uses because of the material's exceptional physical characteristics. Most notable among these properties are the extreme hardness of diamond, its high dispersion index, and high thermal conductivity. These properties form the basis for most modern applications of diamond

The precious stones are diamond; some forms of corundum (ruby, sapphire, Oriental emerald, Oriental topaz, and Oriental amethyst); and emerald. The chief semiprecious stones are aquamarine, amethyst, topaz, garnet, tourmaline, spinel, peridot (see olivine), zircon (see zirconium), chrysoberyl, quartz, opal, turquoise, moonstone, and jade. The organic gems are pearl, amber, coral, and jet; of these, pearl is usually counted as a precious stone.\n\n=)

In the gem business:\n\nCarat (mass) is a unit of mass for gems. In the United States, carat almost exclusively means the unit of mass. \nCarat (purity) or karat is a unit of purity for gold. In the United States, karat almost exclusively means the unit of purity.

The reason they are called "diamonds" is due to their shape. The name Herkimer originates from Herkimer County in New York State from which they are mined.\n\nHerkimer diamonds are quartz crystals. The crystals are fully formed on both ends & are said to be doubly terminated. Sometimes they have smaller crystals sticking out the sides.\n\nQuartz is one of the most common minerals in the earth's crust & is made up of silicon & oxygen. The chemical formula is SiO2. Diamonds are made completely from carbon. The only carbon in a Herkimer diamond is the tiny bits of black organic matter found in them. These are referred to as inclusions.\n\nI have one in my classroom. Kids hear 'diamond' & go nuts. I hear, "How much is it worth??" When I tell them not worth much they usually lose interest. LOL

I think that Diamond is a generic brand of foil and is quite thin. If should be an address to write to on the box of foil. You could also inquire at the store where you purchased the foil--they should atleast be able to give you address from their shipment roster.

A dark green stone with light green flecks..hmm, could be jade.  But it could be something else too....a quick trip to the jeweler or to a gemologist will solve it! Really, all you need to do is get a specific gravity measurement on it (i.e. a ratio between how much the stone weighs in air versus in water).  Jadeite is 3.33 and Nephrite is 2.95.\n\nHowever, there are a few quick tests & observations you can conduct at home that might shed some light on what you have.\n\nHold the stone in your hand.  Does it feel cool to touch?  (You may have seen Chinese or Burmese people touch jade to their cheeks to test its coolness as a sign of authenticity.)  \n\nObserve the texture of the material. If there is a fracture, the texture should be splintery and rough.  If it shows fairly smooth flat surfaces and "faults" (cleavage planes), you may have another type of green stone. e.g. Amazonite. \n\nIf it is polished, does it look like it has a "dimpled" skin? Can you see tiny veining on the surface? If it is translucent, does the material look slightly fibrous?\n\nIt's really hard to say what you've got based on your description.  As a collector, I'm pretty good at visual ID of jade.  If you have a photo, send the url to me and I'll do my best to help!

The dime has an edge with 118 ridges. This coin is 17.91 mm in diameter and is 1.35 mm thick - it is the smallest, thinnest and lightest US coin.

Probably white.  But, double check that a pearl is even a mineral - I don't remember that, but it's been a while
