Amber, Beryl, Chrysoberyl, Coral, Corundum, Diamond, Feldspar, Garnet, Hematite, Jade, Lapis Lazuli, Malachite, Opal, Pearl, Peridot, Quartz, Spinel, Spodumene, Topaz, Tourmaline, Turquoise and Zircon.

It’s 2008 now… have there been new changes on this list? If there are new changes on the list of frequently used gem materials, what are they? Were there new materials discovered? Were some of the said materials on the list of frequently used been removed? If so, what were they?
Please, help this aspiring mineralogist and gemologist!!

Topaz
$14.55 Filmed on locations ranging from Denmark to the Universal backlot, Alfred Hitchcock's Topaz is based on a novel by Leon Uris. Frederick Stafford, a veteran of European-filmed James Bond rip-offs of the 1960s, is cast as Andre Devereaux, a French secret agent assigned to snoop around Cuba in the months prior to the 1962 missile crisis. Someone is supplying Castro -- and, by extension, Moscow -- with NATO secrets; it is up to Devereaux to liquidate the "mole." Aiding Devereaux is CIA agent Nordstrom (John Forsythe) and aristocratic anti-Castro Cuban Juanita (Karin Dor), who happens to be the girlfriend of pro-Castroite Rico Parra (John Vernon). The director seems to be in awe of the fact-based storyline, and as a result, the film is more cut-and-dried than most Hitchcock efforts. Three different endings were filmed for Topaz; the Laserdisc version carries all three, as does the print available to the American Movie Classics cable service. According to the MPAA, the film was originally rated M but later changed to PG; however, a number of home-video issues of Topaz officially list it as "Not Rated." ~ Hal Erickson, Rovi |

True Grit (1969)
$9.74 In fine Hollywood tradition, John Wayne had to play a "one-eyed fat man" before the Motion Picture Academy considered him worthy of an Oscar. In True Grit, Wayne plays grumpy, pot-bellied U.S. marshal "Rooster" Cogburn, hired by 14-year-old Mattie Ross (Kim Darby) to find Tom Chaney (Jeff Corey), who killed her father. The headstrong Mattie could have had her pick of lawmen, but selects the aging Cogburn because she believes he has "true grit" (she talks this way all through the picture, so be prepared). Also heading into Indian territory in search of Chaney is Texas Ranger La Boeuf (Glen Campbell), who wants to collect the reward placed on the fugitive's head for his earlier crimes. Complicating matters are Chaney's scurrilous cronies Ned Pepper (Robert Duvall), Quincy (Jeremy Slate), and Moon (Dennis Hopper), who have no qualms about killing a troublesome teenaged girl like Mattie. While the plot of True Grit, adapted (and streamlined) by Marguerite Roberts from the novel by Charles Portis, maintains audience interest throughout, the glue that truly holds this Western together is John Wayne, delivering one of his finest performances (though some believe he was better in She Wore a Yellow Ribbon). Wayne's casual charisma is infinitely more effective than the mannered method acting of Kim Darby and the floundering non-acting of poor Glen Campbell. And who could not love the climatic face-off between Duvall and company and John Wayne, whose "Fill your hand, you son of a bitch!" is not only a classic bit of dialogue, but the apotheosis of the Wayne mystique. In 1975, Wayne repeated his True Grit characterization opposite Katharine Hepburn in Rooster Cogburn, but the film failed to match its predecessor and the overall effect was blunted. ~ Hal Erickson, Rovi |
