You can also go for a Diopside (color is chrome green) or Dioptase (color is similar to emerald) which is a semi-precious natural green gemstone; a cost-effective alternative of Emerald. Most Diopside from Thailand are color enhanced i.e. treated with either heat or diffusion with mostly glass filling to enhance clarity, so be sure to get a gemstone certificate which mentions its treatments as well.

You can check out following sites for Diopside:

It is hard to find a cut Dioptase gemstone. Mostly they are sold in rough. However, price Dioptase is expensive than Diopside.

Please consult with Srinivasa, if you can wear Diopside as an alternative to Emerald.
