Both of them appear to be natural (probably oiled), their weight is about 0.20ct in total. There is a colorless stone which weights 0,19ct, it appears like a white sapphire. There are smaller colorless stones and they look H color and SI diamonds. They are round, brilliant cut. Observing the photos provided the pendant could be modern.
