Exfoliation is the property of some minerals to break according to certain planes, giving more or less smooth surfaces, called exfoliation planes. This property is closely related to the internal crystalline structure, since there are reticular planes where the particles are located. In some crystals, the arrangement of atoms and the types of bonds favor the presence of certain directions in which the mineral separates more easily when mechanical action is applied. The cleavage planes in the diamond structure run parallel to the faces of the octahedron and correspond to the weakest structural planes. In some cases, exfoliation is used to cut them or to eliminate defective portions of raw specimens, with the least will surely be difficult to choose one or two pieces as favorites, but do you have a preference for any, Benjamín? Benjamín : What is most valuable about the collection is the collection itself , that is, the set of specimens , many rare and valuable, others very common (there are granite and other rocks, pitches and tars, quartz, calcites, fluorites by the dozen.
That said, the most valuable thing is the set of natives and , characteristic of the mines of Central Europe in the first half (golds, silvers, , tellurides, bismuths, antimonies, etc.). Almost all silver sulfides and sulfosalts (, red silvers, , polybasite, freibergite, etc.). And some precious crystallized minerals of various compositions, such as the on the cover, from the famous type locality of Cell Phone Number List the from (Siberia) or the (bismuth Surely we are all familiar to a greater or lesser extent with trophies such as the Salad Bowl, the or the d'Or, coveted by great athletes and admired by the fans, since they represent triumph and effort . In European sports championships, trophies usually consist of large and ostentatious objects such as cups or containers, or medals. But in the United States, championship rings are added to the equation, especially in leagues as recognized as the NFL or the NBA. NFL trophies The American National Football League (NFL) competitions have their origins in the 1920s, sharing prominence with other leagues, such as the American Football League (AFL). Both began talks in 1966 to unite both championships, reaching a preliminary agreement that same year. This is how the well-known Super Bowl came about, which was held for the first time in 1967. The Vince Lombardi Trophy was designed by Tiffany & Co.
And represents a regulation American football The award given to the winning team of each edition is the Vince Lombardi Trophy , a name it has received since 1970, when coach Vince Lombardi, who had led the Green Bay Packers to victories in the first two Super Bowls, died from of cancer. This trophy, which represents a regulation American football, was designed by Tiffany & Co .: valued at $10,000, it measures 56 centimeters, weighs 3.2 kilos, and is made of sterling silver. Each year one of these trophies is awarded to the winner. Champion Rings But in addition, the NFL pays for 150 “champion rings” for the winning team , which are distributed among the players, coaches, staff and management. The history of this type of trophies dates back to the 1920s. The New York Giants were the first team to receive, in 1922, the championship rings as we know them today, in the context of Major League Baseball (MLB). Since then, other Major Leagues have adopted this custom, official in the MLB since 1932. However, it is not an isolated fact: in many tournaments other types of gifts were given to the winners: from watches or cufflinks, to weapons or liquors.
