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.
