- P: Na ke taemane ea 'nete kapa che?A: Ke taemane ea 'nete, empa e lengoa laborateng, eseng ea tlhaho.
B. P: Taemane ee e lengoang lab ke bokae ha e bapisoa le ea tlhaho?
A: E tlase ka 30-70% ho feta ea tlhaho ho boima bo fapaneng le ho hlaka.
C. Q: Na u ka iketsetsa daemane ka mokhoa o ikhethileng?
A: E, re ka khona ho khaola daemane ho latela tlhoko ea hau.
D. P: Phapano ke efe pakeng tsa grade A le Grade B?
A: Sehlopha sa A se na le VS, VVS e hlakileng, ha sehlopha sa B se na le tlhakisetso ea SI1-SI2, ka lentsoe le leng, Kereiti A e hloekile ho feta Kereiti ea B.
E. P: Nako ea ho tsamaisa taelo ke efe
A: Boholo ba boholo bo tla romelloa matsatsing a 3-5 a sebetsang.
