LUTZES
A Banded Lutz is a marble with a single-colored base glass and two sets of two bands alternating with two lutz bands. Lutz is finely ground copper flakes or goldstone. The lutz bands are usually edged by opaque white strands.
The most common base glass is transparent clear. Transparent color base glass is rarer. Semi-opaque base glass (usually colored) is very rare. Opaque base glass is also rare. Marbles with opaque
black bases are the most common of this type. Other colors are rarer.
A few rare examples have only two colored bands, rather than the usual four, or extra colored bands. These are extremely rare.

An Onionskin Lutz is a marble that has an end of day onionskin core with lutz bands and/or lutz sprinkled on the core.
The base color of the core is usually white, with blue, green or red streaks. Usually the streaks are not as pronounced as they
are on an end of day that does not have lutz.
The lutz can vary from a light sprinkling on the core to very heavy lutz bands. Heavy lutz on the core increases the value of the marble. In some instances, the lutz floats on a
layer of clear glass above the core. These are rare and are sometimes called “floaters.”
Lobed and/or cloud examples are known to exist. These are very rare. Marbles that have colored glass surrounding the core and lutz are also very rare.

A Ribbon Lutz is a naked ribbon core swirl with lutz on both edges of the ribbon. There are single ribbon examples and double ribbon examples.
The basic type is transparent clear base with an opaque white single ribbon core. The ribbon usually has transparent color glass over it. There are some marbles with an
opaque-color single ribbon. These are somewhat rarer.
There are examples with a double ribbon, where each ribbon is a different color. These are also rare.
Some marbles are in transparent color glass. The ribbon is always opaque white. These are also rare.

An Indian Lutz has an opaque black base with three or four lutz bands on the surface. The bands are edged with colored strands. Several examples have also been found with colored bands and lutz bands on the surface.
A Mist Lutz is a transparent clear base with a core of a transparent color. There is a layer of lutz just below the surface of the marble, floating between the core
and the surface. Usually the core color is green. Several examples with red or black cores have been found and these are extremely rare. There have also been some lutzes found that
have a solid black core with lutz on the core itself. These are referred to as Solid Core Lutzes.
