Even though it's close, there aren't enough details visible at this size to tell what type of pearl, or to verify if they are pearls because the camera is focused on the background. If you are using a cell phone, try tapping one of the pearls to focus on it and take the photo on white paper or a paper towel so the color will be easier to see. In the top photo, the color and surface are more typically cassis, but could be melo. In the bottom photo, there appears to be more of an orange color. There is some crossover in colors with cassis and melo.
