American Federation of Mineralogical Societies AFMS Approved Reference List of Lapidary Material Names “Gem List” August 1996 Updated January 2003 AFMS Pubications Committee B. Jay Bowman, Chair Internet version of Approved Lapidary Material Names. This document can only be downloaded at http://www.amfed.org/rules APPROVED NAMES FOR LAPIDARY LABELS Prepared by the American Federation Nomenclature Committee and approved by the American Federa- tion Uniform Rules Committee, this list is the authorized guide and authority for Lapidary Label Names for exhibitors and judges in all competition under AFMS Uniform Rules. All materials are listed alpha- betically with two columns on a page. The following criteria are to assist in the selection and judging of material names on exhibit labels. 1. The name of any listed material (except tigereye), which has been cut to show a single chatoyant ray, may be preceded by “CAT’S-EYE”; the name of any material which has been cut to show asterism (two or more crossed rays) may be preceded by “STAR”, i.e.: CATS-EYE DIOPSIDE, CAT’S-EYE QUARTZ, STAR BERYL, STAR GARNET, etc. 2. This list is not all-inclusive as to the names of Lapidary materials which may at some time be exhibited. If a mineral or rock not included in this list is exhibited, the recognized mineralogical or petrological name must be used. The names of valid minerals and valid mineral varieties listed in the latest edition of the Glossary of Mineral Species by Michael Fleisher, or any other authorized reference, will be acceptable as Lapidary names. Varieties need only have variety name listed and not the root species. Names in this list that are indented belong to the generic name that precedes them. Either name may be used, but not both. Consult the Uniform Rules for the approved references. Refer to the Uniform Rules for additional information required to complete the label and note the following items (3) and (4). 3. Guide to capitalization. Gem names when used in labels, titles or headings, are written in all capital letters, but when used within text material, they are not capitalized. 4. Descriptive terms may be placed on the label, in parentheses if so desired, and will be judged for accuracy, spelling and punctuation, i.e. AGATE, (Crazy Lace) or AGATE Lace; AGATE, (Botswana) or AGATE, Botswana; JASPER (Biggs) or TOURMALINE (Bi-Color), or TOURMALINE, Bi-Color, etc. Guide to stones with inclusions (i.e. EPIDOTED QUARTZ) not found in list, see item (5). 5. If a material is cut and polished as a gem stone, then the name of the base material and the inclusions shall be given, i.e., EPIDOTE in QUARTZ, GOLD in QUARTZ, COPPER in CALCITE, COPPER in DATOLITE, MARCASITE in AGATE, GOETHITE in AGATE, GOETHITE in QUARTZ, etc. Guide to synthetic and artificial stones: See items (6) and (7). 6. Any artificial (no natural counterpart) material not listed below must be preceded by MAN-MADE, i.e., MAN-MADE GLASS 7. Any synthetic (having a natural counterpart) material not listed below must be preceded by SYNTHETIC, i.e., SYNTHETIC RUBY. Internet version of Approved Lapidary Material Names.
