Yimaphi amatshe agugu amathekisthi ophawu?

Ama-Gemstones ama-optical phenomena

Ama-gemstone ama-optical phenomena avela endleleni ukukhanya kuhambelana ngayo nesakhiwo sekristallini segugu. Lokhu kuxhumana noma ukuphazanyiswa kungaba ngendlela yokusabalalisa okukhanya, ukucabangela, ukuphazamisa, ukuhlukanisa, ukumisa noma ukudlulisa.

Adularesence

I-Adularescence yinto eluhlaza okwesibhakabhaka ekhombisa indawo eyakhiwe ngamakhabochon eMonstone. Isimo se-shimmer sivela ekusebenzisaneni kokukhanya nongqimba lwamakristalu amancane e- "albite" ematsheni enyanga. Ubukhulu besendlalelo salezi zinhlayiya ezincane bunquma ikhwalithi yokukhanya okuluhlaza okwesibhakabhaka. Nciphisa ungqimba, ngcono i-flash eluhlaza okwesibhakabhaka. Lokhu kuvame ukuvela njengomphumela wokukhanya okukhanyayo. I-Moonstone yi-orthoclase feldspars, elinye igama lingu- "selenite". AmaRoma ayibiza ngokuthi i-Astrion.

Asterism

Ababambi bezinsika ngokuvamile bakhetha ukusika ama-cabochon, uma amatshe aphansi. Kulezi zinhlamvu kanye namatshe lapho ukukhanya kwehla phezu kwendawo ye-cabochon futhi kwenza imisebe enjengezinkanyezi, lo mkhuba ubizwa ngokuthi i-asterism. Kukhona ama-4 ray kanye nezinkanyezi ze-6 zezinkanyezi ezibheke ngokuvamile. Lokhu kwenzeka uma ukuma kwenaliti kufana ne-inclusions noma isilikhi ngaphakathi kwe-crystal ku-axis angaphezu kweyodwa.

Chatoyancy

Kusukela egameni lesiFulentshi "Chat" kusho ikati. I-Chatoyancy isho into efana nokuvula nokuvala iso lekati. Singabona kugugu leso lekati le-chrysoberyl ngokucacile okukhulu. Amatshe ayigugu ekati anebhande elilodwa elibukhali, kwesinye isikhathi amabhendi amabili noma amathathu, agijimela ngaphesheya kwendawo eyakhiwe ngamakhokho. Amatshe ayigugu ekati asesimweni se-cabochon asikiwe agqamisa ukuxoxa. Izinaliti eziqondile zesakhiwo se-crystal zetshe zibheke ngqo kuzimo. Ngakho lapho ukukhanya kuwela phezu kwayo, ibhande elibukhali liyabonakala. Ezimweni ezinhle kakhulu, iso lekati elixoxayo leChrysoberyl libukeka lihlukanisa indawo ibe izingxenye ezimbili. Sibona umphumela wobisi noju lapho itshe lihamba ngaphansi kokukhanya.

Iridescence

I-Iridescence nayo yaziwa nangokuthi i-goniochromism, into lapho ubuso bezinto ezibonakalayo kubonisa imibala eminingana njengengqikithi yokuguqulwa kokubuka. Kungabonakala kalula entanyeni yenjuba, amabhulabhisi ensipho, amaphiko wevemvane, umama wepearl njll Ukungahleleki kwezikhala zomhlaba nezindawo ezinkulu kuvumela ukukhanya kudlule futhi kubonakale emuva emuva kokuvela ezindaweni eziningi (ukuhlukanisa) okubangela umbala omningi okubonakalayo. Ehlanganiswe nokuphazanyiswa, umphumela uyamangalisa. Amapharele emvelo abonisa i-iridescence ehluke kakhulu kumbala womzimba wayo. Amaparele aseTahiti abonisa i-iridescence enkulu.

Dlala ngombala

Igugu elimangalisayo elibizwa ngokuthi i-opal libonisa umbala omuhle. Ama-fire opals avela eLightening Ridge, e-Australia (abonisa ukuguquguquka kwezimagqabhagqabha zemibala ekhanyayo ekhanyayo kumnyama) adume ngalesi simo. Ngenkathi lo mdlalo wombala uwuhlobo lwe-iridescence, cishe bonke abathengisi bamatshe ayigugu bakubiza ngokungafanele ngokuthi "umlilo". Umlilo yigama le-gemological, Ukuhlakazwa kokukhanya okukhombisa ngamatshe ayigugu. Kubonakala ngokujwayelekile kudayimane. Ukusabalalisa okulula kokukhanya. Uma kwenzeka opals akuyona ukuhlakazeka ngakho-ke, kuyimbumba ukusebenzisa igama elithi "umlilo".

Ukushintsha kombala

Isibonelo esihle sokushintshwa kombala yi-alexandrite. Lawa magugu namatshe avela ehluke kakhulu ekukhanyeni kwe-incandescent uma kuqhathaniswa nokukhanya kosuku lwemvelo. Lokhu ikakhulukazi kubangelwa ukwakheka kwamakhemikhali ayigugu kanye nokumuncwa kokukhetha okuqinile. I-alexandrite ibonakala iluhlaza emini futhi ibuye ibonakale ibomvu ekukhanyeni kwe-incandescent. ISafire, futhi i-tourmaline, i-alexandrite namanye amatshe angakhombisa ushintsho lombala.

Labradorescence

I-Labradorescence uhlobo lwe-iridescence, kodwa luqondiswa kakhulu ngenxa ye-crystal twinning. Singayithola ekugatsheni kwe-labradorite.
