If you are planning to buy a morganite diamond engagement ring, given below are some design and setting ideas you can consider. The All-Rose Style Morganite diamonds look incredibly beautiful when they are paired with rose gold. Rose gold bands are available in many shades and you can pick the tone, which matches the best with the morganite diamond that may have tones like pink, peach, purple pink, etc. Diamond or Gemstone Accents To give your morganite diamond engagement ring an added bling, you can opt for the ones with accent stones. Diamond accents provided around the center stone or those set along the length of the band will be a good choice. For a more colorful ring, you can choose colored gemstone accents instead.  A Good Setting You may know that prong and bezel settings are the popular diamond ring settings. In the former style, prongs are used to secure the center stone, and a larger number of prongs means the stone is more secure. While, in bezel settings, the band metal surrounds the edge of the stone and holds the stone better.
