Webster's Revised Unabridged Dictionary
  • Interesting fact: Sherlock Holmes, Sir Arthur Conan Doyle's brilliant detective, arrived on the mystery scene in the late nineteenth century in "A Study in Scarlet" (1887).
    • Brilliant A diamond or other gem of the finest cut, formed into faces and facets, so as to reflect and refract the light, by which it is rendered more brilliant. It has at the middle, or top, a principal face, called the table, which is surrounded by a number of sloping facets forming a bizet; below, it has a small face or collet, parallel to the table, connected with the girdle by a pavilion of elongated facets. It is thus distinguished from the rose diamond, which is entirely covered with facets on the surface, and is flat below. "This snuffbox -- on the hinge see brilliants shine."

    • n brilliant [Cf. F. brillant, a diamond.] The form in which the diamond and other precious stones are cut when intended to be used as ornaments, whenever the shape and cleavage of the uncut stone allow this to be done without too much loss of material. The brilliant is susceptible of many small modifications as regards the size, proportions, and even the number of the facets; but in the most perfect cut there are 58 facets. The general shape of all brilliants is that of two pyramids united at their bases, the upper one being so truncated as to give a large plane surface, the lower one terminating almost in a point. The manner in which the brilliant is derived from the fundamental octahedral form (a in fig. 1) is shown in fig. 1, b and c. The uppermost large flat surface is called the table, and is formed by removing one third of the thickness of the stone; the opposite small end, called the culet or collet, is formed by removing one eighteenth of the thickness of the stone. The girdle is the widest part, and forms the junction-line between the upper part, called the crown, and the lower part, called the pavilion. Fig. 2 shows the top , side , and back views of a modern brilliant cut with 58 facets. T is the table; C, the culet; G, the girdle; A, the templets or bezels (of which there are 4 in all); B, the upper quoins or lozenges (of which there are 4); S, star-facets (of which there are 8 in the crown); E, skill- or half-facets (8 in the crown and the same number in the pavilion); D, cross- or skew-facets (8 in each part); P, pavilion-facets (4 in number); Q, lower or under-side quoins (of which there are 4)—making 58 facets in all. Sometimes extra facets are cut around the culet, making 66 in all. In fig. 3, a and b show top and side views of the single cut, or half brilliant; c is a top view of the old English single cut. In fig. 4, a, b, and c show top, side, and back views of a brilliant with 42 facets. In fig. 5, a, b, and c show top, side, and back views of the split or double brilliant, with 74 facets. In fig. 6, a, b, and c show top, side, and back views of the Portuguese cut, which has two rows of rhomboidal and three rows of triangular facets above and below the girdle. In fig. 7, a gives a side view of the double rose, sometimes called the briolette when several more rows of triangular facets are added. Fig. 8 shows the form and size of the famous Regent diamond, belonging to the government of France. It weighs 136¾ carats, and is generally considered the most valuable diamond known, having been estimated by experts at twelve million francs. It comes very near being a perfect brilliant in form, but is a little too thick or deep for its breadth, while the Koh-i-noor, as cut since it came into the possession of the Queen of England, is too thin or spread. Any gem may be cut in brilliant form; but when the word brilliant is used by itself, it is always understood to mean a diamond.
