Petrification yimbaho ni ibuye ryihariye ryigiciro cyinshi, rizwi kandi nka petrification yinkwi, bivuga guhindura buhoro buhoro inkwi zihinduka amabuye y’ibuye mu gihe cya geologiya. Ubu bwoko bwamabuye busanzwe bufite imiterere nimiterere yibiti, kandi bugumana imiterere yinkwi, ariko ingirangingo zayo zasimbuwe rwose cyangwa igice cyacyo. Ibiti bya peteroli birashobora gutemwa, gusukwa no kubahwa kugirango bikore imitako itandukanye n'imitako nka pendants, impeta na bracelets. Ibara ryabyo nimiterere biratandukanye bitewe namabuye arimo, ariko amabara asanzwe arimo umukara, umuhondo, umutuku, numukara.
Igiti cyometseho ibiti bivuga igisate kinini cyibikoresho bya agate byakozwe nyuma yimikorere. Ihuza ibiranga ibiti na agate ibuye, hamwe nimiterere idasanzwe. Icyapa cya agate gikozwe mubiti gikoreshwa mugushushanya imbere nibikoresho byubaka, kandi birashobora gukoreshwa mugukora ibisenge, inkuta, amagorofa, nibindi.
Mugihe uhisemo icyapa kibiti, ugomba kwitondera ingingo zikurikira:
1. Hitamo isoko isanzwe itanga isoko cyangwa isoko yumwuga wo gushushanya kugirango ubone ubwiza nukuri kwibicuruzwa.
2. Witondere kureba niba ibara n'ibara ryibiti bya agate byimbaho bisa kandi nibisanzwe, kandi wirinde ibice bigaragara, inenge cyangwa itandukaniro ryamabara.
3. Reba niba ingano nubunini bwikibaho cya agate icyapa kibereye umushinga wo gushushanya.
4. Mugihe ushyiraho kandi ugakoresha plaque ya agate plaque, birakenewe gukurikiza ibyubatswe byumwuga no kubitaho kugirango ubone ubwiza bwigihe kirekire nibikorwa.
Mw'ijambo, icyapa cyibiti cyibiti ni ibintu biranga ibintu byiza kandi byiza byo gushushanya, bikwiranye no gushushanya imbere imbere no gukenera imyubakire.
