Beads may be some of the most difficult items to judge their material or age based on low resolution pictures. Almost most of the so called jade beads listed on eBay by sellers in mainland China were either made of dyed agate or worse glass. About six years ago, one still could buy beads made of jadeite in reasonable prices. It is actually harder to find necklace made of nephrite since the demand for them may not be as high as that of jadeite and labor cost for making them are almost as high. Most of the genuine nephrite necklace are therefor older pieces, probably made in the 60s or earlier. During the 60s, there were a lot of nephrite jade found in Taiwan but now their nephrite mines exhausted after one decade.
I believe your green necklace can be made of nephrite if the beads can pass the scratch test and the gold beads are indeed 14k gold.
I do not know what the black beads were made of. It is quite rare to find 100% black nephrite jades, they are actually rarer than green one. Some time they may be dark green and look black in pictures. If they can pass the scratch test,they can be nephrite, onyx, jadeite, etc. If indeed nephrite, like from Australia, it would be worth more than the green one.
If both are indeed made of nephrite jade and the gold beads are indeed 14k gold, then they may indeed each worth a few hundred dollars or more. Thank you for sharing.
