the reflecting quality and brilliance of the surface of a mineral; shining by reflected light, gloss, sheen.

The luster is determined by the amount of light reflected by the fiber. Alpaca differs in amount and character of luster, depending both on the structure of the fiber surface and on the size and straightness of the fibers. Suri Fiber is thought to have more luster than Huacaya fiber.

The reflection of light from the surface of a mineral.

(lus'-ter) The way in which a mineral reflects light from its surface. Luster is a function of the smoothness of the mineral surface and its reflectivity. Categories of luster include metallic, submetallic, and within nonmetallic; vitreous, adamantine, pearly, earthy, and dull.

The reflectance and scattering of light on the surface of the fiber. For example, nylon with a dull luster is very flat and dull looking, with a maximum of light scattering behavior. Nylon with a bright luster is shiny and sparkly, with a minumum of light scattering behavior.

A) Shine or "look" of a gemstone due to reflection of light off the surface. B) The unique, internally emanating glow that distinguishes pearls from all other gems.

(1) A shiny metallic effect made by painting the surface with metallic oxides that have been dissolved in acid and mixed with an oily medium. Firing in oxygen-free conditions at a temperature of about 1150° F (600° C) causes the metal to deposit in a thin film that, after cleaning, has a distinctive shiny surface. (2) A glass lighting device, such as a candelabrum or candlestick, decorated with hanging prismatic drops.

The light reflective quality of fiber exhibited in shine and gloss.

Having the appearance of depth. The term is also used as a synonym for gloss.

Refers to the sheen or brightness of fabrics, fibers and yarns.

Description of a pearl's shine. The higher the luster, the greater the pearl's value.

A metal borne reflective color that is fired on glass or ceramic.

Refers to the brightness a piece of jewelry reflects.

Glossy, pearly coat to make a bead shinier.

The glossy brilliance of a coin seen from the reflection of light off the flow lines.

The appearance of a surface in reflected light.

Glossy, almost oily finish.

The way in which a mineral shines because of reflected light. Luster can be Described as vitreous (glassy), waxy, resinous, metallic, or dull.- M ~ O

A wool characteristic determined by the amount of light reflected by the fiber.

The outward appearance of a gem or organic material. Luster is important especially when evaluating the quality of pearl.

a metal oxide decoration fired onto a stein; including occasional platinum accents on early Mettlach steins, metal alkali sheens all over some glass steins, and many other types.

Brightness or sheen of fibers, yarns, carpet or fabrics.

One of the most important factors determining the value of a pearl, luster refers to the reflective quality or brilliance of the surface of a pearl. Luster is related to the thickness and quality of the outer layers of nacre which capture and throw back the light, giving pearls their unique and awesome “glow.” The more lustrous the pearl, the more it shines and reflects light and images. The more brilliant and mirror-like the surface of the pearl, the higher its quality and value. Pearls with low luster appear white or chalky, rather than brilliant and shiny. Though luster is not the same as “surface”, the two are related and the luster is usually diminished by surface imperfections.

Term for the amount and strength of light reflected from a coin's surface .Luster is the result of light reflecting on the flow lines.

the amount and strength of light reflected from the surface of a coin

The brilliance of a gem which comes from the light which is reflected off of the stone's surface. (see sheen).

The way a mineral surface scatters light.

The hue and depth of reflection from pearls, opals or other opaque stones.

A stone's luster is its sparkle or sheen - the way it reflects light. The luster depends on the nature of the stone's surface reflectivity. Some types of luster include: adamantine (also called brilliant or diamond like, like a faceted diamond), earthy (with little reflectivity- also called dull, like shale or clay), greasy (like nepheline or apatite), metallic (also known as splendent, like pyrite or marcasite), resinous (like amber), pearly (with an iridescent reflectivity, like pearls or mica), pitchy (tarry minerals that are radioactive, like uraninite), silky (with a fibrous structure, like some tiger's eye or satin spar), vitreous (also known as glassy, like olivine, transparent quartz, or obsidian), and waxy (like halite or turquoise). A pearl's luster is derived from its nacre.

Sheen of yarns, fiber, or finished fabrics.

The appearance of a mineral when light reflects off its surface. Among the terms used in identifying luster are metallic, vitreous (glassy), and dull.

Brightness or reflectivity of fibers, yarns, carpets, or fabrics. Synthetic fibers are produced in various luster classifications including bright, semi-bright, semi-dull, and dull. Bright fibers usually are clear (have no which pigment) whereas the duller designations have small amounts of white pigments such as titanium dioxide. Luster of finished carpet also depends upon yarn heatsetting methods, dyeing, and finishing. In high traffic commercial areas duller carpets are often preferred for soil hiding ability.

Gloss of a finish.

Considered the radiance or depth of inner light refraction of a pearl and determined by the quality of the nacre coating. Luster is created by tiny crystals of nacre built up over the irritant. Natural pearls tend to have thicker nacre than cultured pearls, hence deeper luster. Dahlia pearls have thicker nacre than most other cultured pearls so our luster is very high.

The glossy appearance of the surface of a coin. Although normally brilliant, with time luster may become dull, frosty, spotted or discolored.

The brilliance or shine on a metal. Luster is considered to be one of the four most important factors in appraising the value and grade of a coin. Alternate spelling: Lustre.

Fact or quality of shining with reflected light; shine or sheen; gloss.

A reference to the brightness of an object that shines with reflected light rather than producing its own.

A sheen or radiance of a coin's surface; resulting from reflection of light off flow lines caused by striking
