Cena diamant\u016f?<\/h2>\n

V tvorb\u011b ceny diamant\u016f hraje d\u016fle\u017eitou roli tak\u00e9 tzv. Rapaport Diamond Report. Jednodu\u0161e \u0159e\u010deno, jedn\u00e1 se o formu velkoobchodn\u00edho cen\u00edku diamant\u016f s hmotnost\u00ed do 2,99 kar\u00e1tu. Ceny uv\u00e1d\u011bn\u00e9 v p\u0159ehledu jsou sestavov\u00e1ny na z\u00e1klad\u011b anal\u00fdzy trhu a pro obchodn\u00edky s diamanty jsou z\u00e1vazn\u00e9. A co kameny s v\u00e1hou od 3 kar\u00e1t\u016f v\u00fd\u0161e? Ty se obchoduj\u00ed formou aukc\u00ed a jejich cena je tvo\u0159ena na z\u00e1klad\u011b aktu\u00e1ln\u00ed nab\u00eddky a popt\u00e1vky.<\/p>\n

A je\u0161t\u011b jedna d\u016fle\u017eit\u00e1 v\u011bc, kterou je t\u0159eba p\u0159i po\u0159izov\u00e1n\u00ed diamant\u016f vz\u00edt v \u00favahu.

Jednoduchou n\u00e1sobilku nelze uplatnit z prost\u00e9ho d\u016fvodu. Pokud je toti\u017e kvalita obou kamen\u016f stejn\u00e1, prakticky v\u017edy je ten v\u011bt\u0161\u00ed pova\u017eov\u00e1n za vz\u00e1cn\u011bj\u0161\u00ed, a t\u00edm tak\u00e9 dra\u017e\u0161\u00ed.<\/p>\n

Jak u\u017e bylo uvedeno, obchodn\u00edci s diamanty jsou povinni v souvislosti s cenou dodr\u017eovat \u0159adu z\u00e1sad. Sv\u00e1 rozhodnut\u00ed o n\u00e1kupu kamen\u016f proto realizujte v\u00fdhradn\u011b u prodejc\u016f, kte\u0159\u00ed maj\u00ed prokazateln\u011b p\u0159\u00edm\u00e9 vazby na trh s diamanty a nejsou pouze na \u00farovni smluvn\u00edch distributor\u016f.

P\u016fvod diamant\u016f<\/strong><\/h2>\n

P\u016fvod diamant\u016f na Zemi je pom\u011brn\u011b jasn\u00fd a detailn\u011b popsan\u00fd. V\u00edme tak, \u017ee vznikly p\u0159ibli\u017en\u011b p\u0159ed 100 miliony let p\u0159i krychlov\u00e9 krystalizaci atom\u016f uhl\u00edku. V\u00edme tak\u00e9, \u017ee cel\u00fd proces se odehr\u00e1val v hloubk\u00e1ch 100 a\u017e 200 kilometr\u016f pod zemsk\u00fdm povrchem za extr\u00e9mn\u00edho tlaku 70 tun na centimetr \u010dtvere\u010dn\u00ed a p\u0159i teplot\u00e1ch dosahuj\u00edc\u00edch a\u017e 1 300 \u00baC. Nezn\u00e1m\u00e1 nen\u00ed ani informace, \u017ee se kameny d\u00edky sv\u00e9 mimo\u0159\u00e1dn\u00e9 tvrdosti dok\u00e1zaly bez probl\u00e9mu pohybovat sope\u010dnou horninou sm\u011brem k povrchu. P\u0159esto se u n\u011bkter\u00fdch kamen\u016f objevuj\u00ed hypot\u00e9zy o jejich mimozemsk\u00e9m p\u016fvodu.<\/span><\/p>\n

Nej\u010dast\u011bji jde o n\u00e1zor, \u017ee asi p\u0159ed 3 miliardami let se n\u011bkter\u00e9 diamanty dostaly na na\u0161i planetu po sr\u00e1\u017ece s asteroidem. My\u0161lenka, kterou zast\u00e1v\u00e1 Stephen Haggert z Floridsk\u00e9 univerzity, se pochopiteln\u011b net\u00fdk\u00e1 v\u0161ech kamen\u016f, ale pouze t\u011bch, kter\u00e9 jsou ozna\u010dov\u00e1ny za \u010dern\u00e9. Tyto domn\u011bnky se op\u00edraj\u00ed p\u0159edev\u0161\u00edm o fakt, \u017ee \u010dern\u00e9 diamanty obsahuj\u00ed nezanedbateln\u00e9 mno\u017estv\u00ed vod\u00edku. A to by nahr\u00e1valo pr\u00e1v\u011b vesm\u00edrn\u00e9mu p\u016fvodu.<\/p>\n

P\u0159esto bude realita mnohem prost\u0161\u00ed. Co se t\u00fdk\u00e1 samotn\u00e9 barvy kamen\u016f, nejedn\u00e1 se o skute\u010dn\u011b \u010dern\u00e9 kusy. Diamanty vznikly standardn\u00ed cestou, obsahuj\u00ed v\u0161ak vysok\u00e9 mno\u017estv\u00ed cizorod\u00fdch l\u00e1tek a jev\u00ed se proto jako \u010dern\u00e9.<\/p>\n

O diamantech<\/h2>\n

Je\u0161t\u011b d\u00e1l za\u0161la studie univerzity v americk\u00e9m Ohiu. V\u011bdci se v n\u00ed pokusili prok\u00e1zat, \u017ee ve vesm\u00edru m\u016f\u017ee existovat planeta tvo\u0159en\u00e1 diamanty.

Nav\u00edc povrch planety je tvo\u0159en grafitem a samotn\u00e9 diamanty by se m\u011bly nach\u00e1zet a\u017e kolem 150 kilometr\u016f pod povrchem.<\/p>\n
