4. And then they faceted it very carefully; they burnished (polished) it and gave it the final luster. 5. _Ytech quahuitl yn quipetlaua ynic pepetlaca, ynic motonameyotia ynic tlanextia._ 5. They polished it set in wood, so that it comes to be very brilliant, shining, glossy. 6. _Anoço quetzalotlatl ynitech quilau ynic quicencaua ynic quiyecchiua yn intultecayo tlatecque._ 6. Or they polish it mounted in bamboo, and the lapidaries finish it thus, and conclude their work. 7. _Auh çannoiuhqui yn tlapaltehuilotl ynic mochiua ynic mocencaua._ 7. And in the same manner they work and smooth amethyst. 8. _Achtopa quimoleua quihuipeua teputztica yn tlatecque yn tulteca ynic yyoca quitlatlalia yn qualli motquitica tlapaltic yn itaqui._ 8. In the first place the lapidary artisans break into pieces the amethyst and crush it with an instrument of copper, for they work only the beautiful pieces which are entirely reddish. 9. _Çan niman yuhqui tlatlalia yn campa monequiz quimoleua tepuztica._ 9. They do not set up the precious stones named in this manner, except in the parts where it is necessary, when they break them with the copper instrument. 10. _Auh niman quichiqui quixteca yoan quitemetzhuia yoan quipetlaua ytech quahuitl yn tlapetlaualoni ynic quiyectilia ynic quicencaua._ 10. Then they scrape it, and they facet it, and they smooth it, and they polish it, mounted in wood, set on the instrument called polisher or burnisher, and they manufacture and finish it. 11. _Auh yn yehoatl yn moteneua eztecpatl ca cenca tlaquauac chicauac camo ma vel motequi ynica teoxalli._ 11. The stone called blood silex (heliotrope) is very hard and very strong, and they do not cut it well with emery. 12. _Çaçan motlatlapana motehuia._ 12. They break it and they cut it up in any kind of way. 13. _Yoan motepehuilia yn itepetlayo yn amo qualli, yn amo uel no mopetlaua._ 13. And they throw away the vein-stone, the useless stone, that which does not lend itself readily to polishing. 14. _Çan yehoatl mocui motemolia yn qualli, yn vel mopetlaua yn eztic, yn uel cuicuiltic._ 14. They do not take or seek except the beautiful pieces that lend themselves to good polishing, the red-banded, that permit themselves to be well cut. 15. _Michiqui atica yoan ytech tetl cenca tlaquauac vnpa uallauh yn matlatzinco._ 15. They rub them with water and mounted in a very hard stone that comes from the country of Matlatzinca [district of Toluca]. 16. _Ypampa ca uel monoma namiqui, yniuh chicauac tecpatl noyuh chicauac yn tetl, ynic monepanmictia._ 16. And because these two stones are companions, the one to the other, as the silex is very hard, so the stone is hard, they kill one another (the one kills the other). 17. _Çatepan mixteca yca teoxalli yoan motemetzhuia yca ezmellil._ 17. Then they facet and polish them by means of emery. 18. _Auh çatepan yc mocencaua yc mopetlaua, yn quetzalotlatl._
