Abbreviations and terms in our lists

Condition/quality   Note: we evaluating of the old and more critical system

GEM The shells have no discernible malformation or flaws. The specimen is completely adult and of average size.
The shells have a very small fault or a malformation that is difficult to find. No optical difference from GEM. We also often classify GEM - specimens so, just to be on the safe side.
F++ (FINE++) Shells have a (small) perceptible fault or a malformation, which does not damage the appearance of the specimen. 
F + (FINE+) Shells have perceptible faults, growth lines, or malformations, which are normal for the species. These specimens are still excellent for a collection and are much more reasonably priced than GEM - shells.
F (FINE) Shells with a (small) break, a growth line, scars, a malformation, or other flaw. Also very fresh specimens that are found dead (fresh dead) are often classified as FINE.
GOOD Shells are damaged to varying degrees.  Some species only exist in this quality as appropriate specimens. Usable for a representation of the species.
FAIR Normal beach finds (empty shells) with the usual damage, breakage, and malformation. Not suitable for collections, maybe as additional pieces for study purposes, rather than for decoration or handycraft work. We do not deal in these shells, however.
Additional information regarding the found:
FRESH DEAD Found dead in the water or on the beach. Very fresh specimen without the normal BEACH - characteristics. We also usually give a condition description (from Good to Fine).
BEACH Empty shell found on the beach, abrasion, and bleaching of the specimen. The specimens we offer have no great damage. Specimens in good quality are owing to smaller prices often more popular.
Additional information on the specimens:
w/a with mollusks (dried or in alcohol), desirable for study purposes for some species.
Only stocked in individual cases.
w/o with operculum
with periostracum
malformation or malformations on the shell. The malformation is NOT damage;
malformed shell, often flattened or constricted at the ends ("beaked").
SINISTRAL left-spiraling ("left handed")  shell. There are species whose shells are naturally left wound, but also left-spiraling specimens of species that are normally right-spiraling ("right handed", dextral).
ALBINO white shell of a normally different-colored species. Not a bleached specimen.
dark to black shells of a normally lighter (also different-colored) species
tiny tiny (adult) specimen under 5 mm. These are usually correspondingly small species.
dwarf dwarf form (adult) of a normally larger species
GIANT giant specimen for the respective species
