a “silver looking diamond ring”
10K NDI is engraved in the inside of the ring
with 19 tiny “diamonds” or “stones” on it
the back is not enclosed, it is open and you can see the bottom of the stones, don't know if they’re real or not.

A “gold looking necklace”
it looks plated.
heart with 8 'diamonds or stones” down the side of it

the chain on the necklace is little, i cant see all of the engraving, but it says its 10K too.

DO YOU THINK THESE ARE WORTH ANYTHING?
THE DIAMONDS DONT FOG, BUT MANY STONES DONT.
HELP! =)

Answer:
Sounds like the metal is 'real', 10K gold (white for the ring, yellow for the necklace). The stones could be any colorless stone, diamond, cubic zirconia, clear quartz, crystal, glass. 10K gold is usually used for lower value jewelry. The NDI is probably just the manufacturer or designer stamp. The value of the jewelry will depend on the weight of the gold and what sort of stones they’re. Even if they’re diamonds, due to the fact that they’re very small, the value won't be that much.
