Samuel Johnson's Dictionary

  1. Diamondnoun

    The diamond, the most valuable and hardest of all the gems, is, when pure, perfectly clear and pellucid as the purest water; and is eminently distinguished from all other substances by its vivid splendour, and the brightness of its reflexions. It is extremely various in shape and size, being found in the greatest quantity very small, and the larger ones extremely seldom met with. The largest ever known is that in the possession of the great Mogul, which weighs two hundred and seventy-nine carats, and is computed to be worth seven hundred and seventy-nine thousand two hundred and forty-four pounds. The diamond bears the force of the strongest fires, except the concentrated solar rays, without hurt; and even that infinitely fiercest of all fires does it no injury, unless directed to its weaker parts. It bears a glass-house fire for many days, and, if taken carefully out, and suffered to cool by degrees, is found as bright and beautiful as before; but if taken hastily out, it will sometimes crack, and even split into two or three pieces. The places where we have diamonds are the East Indies and the Brasils; and though they are usually found clear and colourless, yet they are sometimes slightly tinged with the colours of the other gems, by the mixture of some metalline particles. John Hill on Fossils.

    Etymology: diamant, French; adamas, Latin.

    This diamond was my mother’s: take it, heart;
    But keep it ’till you woo another wife. William Shakespeare, Cymbeline.

    Give me the ring of mine you had at dinner;
    Or, for the diamond, the chain you promised. William Shakespeare.

    I see how thine eye would emulate the diamond: thou hast the right arched bent of the brow. William Shakespeare, Mer. Wives of Winds.

    The diamond is preferable and vastly superior to all others in lustre and beauty; as also in hardness, which renders it more durable and lasting, and therefore much more valuable, than any other stone. John Woodward, Mett. Foss.

    The diamond is by mighty monarchs worn,
    Fair as the star that ushers in the morn. Richard Blackmore, Creation.

    The lively diamond drinks thy purest rays,
    Collected light, compact. James Thomson, Summer, l. 140.


  1. Diamond

    Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very high refractive index and a relatively high optical dispersion. Most natural diamonds have ages between 1 billion and 3.5 billion years. Most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the Earth's mantle, although a few have come from as deep as 800 kilometres (500 mi). Under high pressure and temperature, carbon-containing fluids dissolved various minerals and replaced them with diamonds. Much more recently (hundreds to tens of million years ago), they were carried to the surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites. Synthetic diamonds can be grown from high-purity carbon under high pressures and temperatures or from hydrocarbon gases by chemical vapor deposition (CVD). Imitation diamonds can also be made out of materials such as cubic zirconia and silicon carbide. Natural, synthetic and imitation diamonds are most commonly distinguished using optical techniques or thermal conductivity measurements.


  1. diamond

    A diamond is a hard, transparent precious stone typically colorless or slightly yellow, made up of carbon atoms arranged in a crystal lattice structure. It is known for its exceptional hardness, brilliance, and durability, making it highly desired for use in jewelry and various industrial applications.

    a precious stone or gem excelling in brilliancy and beautiful play of prismatic colors, and remarkable for extreme hardness

  2. Diamondnoun

  8. Etymology: [OE. diamaund, diamaunt, F. diamant, corrupted, fr. L. adamas, the hardest iron, steel, diamond, Gr. . Perh. the corruption is due to the influence of Gr. transparent. See Adamant, Tame.]


  1. Diamond

    In mineralogy, diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells. Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities color diamond blue, yellow, brown, green, purple, pink, orange or red. Diamond also has relatively high optical dispersion, which results in its characteristic luster. Excellent optical and mechanical properties, notably unparalleled hardness and durability, make diamond the most popular gemstone.
