A necklace of nine gold capped agate beads, carnelian, quartz and jasper, alternating with ten complex seven layer granulated gold beads, each faced with two six sided faceted carnelian beads. The gold bead caps and the gold beading tips are decorated with a border of grains on their ends. A hook and eye clasp completes the necklace. The gold is all 20k. The stone beads are all biconical tapered barrel beads except the two at the back which are straight cylindrical tubes. These beads are 5mm in diameter and with the caps, 2.63 cm in length. The cap ends are 6.8 mm in diameter. The diameters of the drill holes are 1.8 mm and 2 mm. The next pair forward are yellowish translucent quartz bicones, one 1.9 cm in length, the other 2 cm. The beads are 7.8 mm and 8 mm in diameter at the center and have drill holes of 3mm. The end widths are 5 mm. The over all lengths with the caps are 2.9 cm and the cap ends have a diameter of 7 mm. The third set of agate beads are quartz with carnelian banding. They are 1.9 cm in length, 6.8 mm and 7 mm wide at the center and 6 mm and 6.3 mm wide at the ends. The hole diameters are 3 mm. The overall lengths with the caps are 2.9 cm and the cap ends have a diameter of 7.2 mm. The pair on either side of the center bead are jasper with dark red center bands with opaque white and bluish white bands quartz bands and yellow jasper ends. They are 1.75 cm in length, 7.5 mm wide at the center , 5 mm end width and hole diameters of 3mm. The overall length with the bead caps is 2.4 cm and the diameters of the end caps is 7.2 mm. The center bead is red jasper with a length of 1.96 cm and a center diameter of 1 cm. The diameter of the ends is 5.5 mm. The diameter of the drill hole is 2.8 mm. The overall length of the bead with the gold caps is 3.3 cm. The ends of the caps are 8.8 mm in diameter. The twenty six sided carnelian beads range in size from 5.7 mm in length to 5 mm. The diameters are 8 mm to 5.9 mm. The diameters of the drill holes are 1.8 mm. The large complex granulated gold beads are 6.5 mm in length and 6.9 mm in width at the widest point. The two cylinder beads at the back of the necklace are probably two thousand years old as is the center jasper bead. All the other agate barrel beads are four thousand years old. The shapes are right for this period but the large drill holes of 3 mm and larger are a sure indication. Drill hole diameters of 2 mm are usually about two thousand years old if the shapes of the beads are typical of that era as well. The six sided carnelian beads may also be from this middle period but they may later. When diamond drills were used the drill holes were typically much smaller. The dating is uncertain.
