"14k" likely refers to the gold's karat purity, meaning the ring is 58.3% gold. "DRI" may indicate a diamond simulant, while "CZ" stands for Cubic Zirconia, a synthetic gemstone. So, the ring features a 14k gold setting with either DRI or Cubic Zirconia stones.
10k refers to the weight of the stone or stones. CZ is cubit zirchonia.
The stone is worthless. The gold is worth the going rate.
