The Egyptian jewelry maker did not use precious stones. What he held
most valuable were semi-precious stones such as malachite, turquoise,
quartz, olivine, red jasper, lapis lazuli, amazonite and other materials
obtained locally in the hills and deserts of Egypt and from creatures
which inhabited the Nile Valley. 

Colors were chosen for their amulet significance or underlying symbolism. 
Green is the color of growing crops, new life and resurrection.  This circa
2006 A.D. museum piece uses black and green jasper with surgical
steel wires.                                                                        $35
