Ku dhammee weedhan soo socota: Sanadihii ugu horreeyay ee macdanta safirka Yogo, ka hor inta safirka Yogo uusan helin sumcadiisa gaarka ah, safirka Oriental waxaa lagu iibiyay Montana iyagoo sheeganaya inay yihiin safir Yogo, halka Yurub, safir Yogo waxaa loo iibiyay sida safirka Oriental. Si kastaba ha noqotee, safayrada Yogo waxay noqdeen kuwo caan ah. Paulding Farnham (1859<unk>1927) wuxuu ku isticmaalay safirada Yogo dhowr dahab oo uu u sameeyay Bandhigga Caalamiga ah ee 1900 ee Paris, halkaas oo safirada Yogo ay ka heshay billad qalin ah dhammaan dhagaxyada qaaliga ah ee midabka iyo cad. Dahabka safayrka ah ee Yogo ayaa sidoo kale ku guuleystay billad naxaas ah.
Bandhigga iibsiga Louisiana ee 1904 ka dhacay St. Louis, Missouri. Farnham wuxuu ahaa abuuraha dahabka ugu quruxda badan ee abid laga sameeyay safirada Yogo, Tiffany Iris Brooch oo cabirkiisu yahay, oo ah dahabka brooch, oo ay ku jiraan 120 safir Yogo oo platinum ah, waxaana la iibiyay Maarso 17, 1900, $ 6,906.84. Sanadkii 1923-kii, Marwada Koowaad Florence Harding waxaa la siiyay giraan "Montana oo dhan" oo laga sameeyay safaaradda Yogo iyo dahabka Montana. Sanadkii 1952-kii, Gadsden waxay siisay madaxweyne Harry Truman, xaaskiisa Bess, iyo gabadhooda Margaret, safayr Yogo ah oo la jaray. Sapphires badan oo Yogo ah ayaa sidoo kale lagu iibiyay Yurub, maadaama qaar ka mid ah macdanta Yogo ay sameeyeen danaha Ingiriiska. Safiirada Yogo waxaa laga yaabaa inay ku jireen aruurinta shaqsiyadeed ee qaar ka mid ah xubnaha qoyska boqortooyada Ingiriiska sannadihii 1910-meeyadii, laakiin sheegashada xayeysiinta ah ee ah in safiirada Yogo ay ku jiraan mid ka mid ah dahabka taajka ee England si dhammaystiran looma xaqiijin karo ama looma diidi karo. Sheegashooyinka ah in jawharad ku jirta giraanta ballanqaadka ee Lady Diana Spencer iyo Kate Middleton ay tahay Yogo waa shaki; jawharad ayaa loo maleynayaa inay asal ahaan ka timid Sri Lanka. Sheekada ah in jawharadku yahay Yogo waxaa loo raad raaci karaa maqaal 1984 "Los Angeles Times" oo ku tilmaamay giraanta inay tahay safayr, oo uu soo xigtay madaxweynaha Intergem Dennis Brown oo sheegtay in jawharadku laga yaabo inuu ka yimid miino Yogo oo ay leeyihiin Ingiriiska.
