M. Flynn makes jewelry in 14k rose, white and yellow gold. We also make jewelry in 18K yellow, white and rose gold which is the standard in Europe. 14K and 18K refers to the amount gold in the metal mix. 18K has 75% pure gold while 14K has a little more than 58 % gold. We always tell people that 18K is better for people with metal allergies but it will have a richer gold look than 14K.
