Cremation hlaws yog hlaws crafted los ntawm tus neeg tuag cov tshauv kom zoo li gemstones. Cov hlaws dai no feem ntau tshwm xim xiav -ntsuab ntsuab, txawm tias lawv tuaj yeem ua rau xim liab, ntshav, lossis dub. Cov txheej txheem tsim khoom suav nrog kev tso cov tshauv mus rau ultra- kub kub kom yaj thiab crystallize lawv; tag nrho cov txheej txheem yuav siv li ntawm 90 feeb. Feem ntau, cov tshauv ntawm ib tus neeg tawm los txog plaub mus rau tsib lub vials me me ntawm cov hlaws dai; Txawm li cas los xij, nyob rau hauv cov ntaub ntawv ntawm cov neeg hluas-vim lawv cov pob txha ceev dua- qhov no tuaj yeem ncav cuag li yim vials.
Cremation diamonds xa mus rau pob zeb diamond tsim los ntawm kev hloov cov tshauv ntawm ib tug cremated neeg mus rau "sparkling gems." Lub hauv paus tseem ceeb ntawm cov txheej txheem tsim khoom no yog nyob rau hauv kev rho tawm cov ntsiab lus ntawm cov hmoov tshauv, uas feem ntau muaj cov ntsiab lus carbon ntawm li 1% txog 4%. Thawj txoj hauv kev ua haujlwm yog Siab-Siab, Siab-Temperature (HPHT) synthesis: cov pa roj carbon rho tawm tau hloov mus rau hauv graphite thiab muab tso rau hauv tshwj xeeb siab-siab, siab- cov khoom siv kub. Siv lub pob zeb diamond ntuj ua "noob" siv lead ua, cov txheej txheem simulates subterranean geological ib puag ncig kom loj hlob pob zeb diamond siv lead ua; tag nrho cov txheej txheem yuav tsum tau rau rau mus rau yim lub hlis kom tiav. Chemical Vapor Deposition (CVD) kuj tseem siv tau los ua lwm txoj hauv kev.
Vim tias muaj cov pa roj carbon tsawg nyob hauv tib neeg cov hmoov tshauv, kev tsim cov pob zeb diamond loj dua feem ntau xav tau qhov sib ntxiv ntawm chav kuaj- qib carbon ntshiab; yog li ntawd, qhov feem pua ntawm cov pa roj carbon monoxide tau muab los ntawm cov tshauv hauv cov khoom kawg yuav qis dua -nrog qee cov ntaub ntawv qhia tias nws suav txog kwv yees li 10%. Cov pob zeb diamond ntxhib uas tau tshwm sim yuav tsum tau txiav, shaping, thiab polishing kom tau raws li cov hniav nyiaj hniav kub- cov qauv qib, thiab tuaj yeem hloov kho ntxiv los ntawm cov txheej txheem xws li laser inscription.
