Hi, everyone. I am interested in the Diamelia but would like to be extra certain before purchasing because of the stores' restocking charges. I know of their basic differences -- Diamelia has a smooth, thicker girdle unlike diamond, NEO resembles diamond in specs, and H&A has the H&A cut but less sparkle. I have read all the talk.jewelry threads on diamelia but am still unsure. What do you think of the three types of gems? Which is your favorite? I would love to see pictures of your gems! Thank you!
