The first morganite crystal was discovered by Mr. J.P.Morgan in 1911 in Madagascar and thus this gemstone was named after him. Although morganite gemstone is rarer than aquamarine gemstone. It has not been able to capture the market as a fine gem to be used in jewelry. Though in the recent times a demand has been seen in the consumers for morganite earrings and morganite rings. The pink morganite also goes very well with the yellow colour of a gold ring.

Morganite gemstone has a refractive index of 1.583 to 1.590 and specific gravity of 2.80 to 2.91.

Morganite-Pink Beryl Rough This pink beryl morganite derives its colour from the alkali metals caesium and rubidium present in it. It is found in pink, rose, peach and salmon colours, pink and rose being more popular among the four colours. In the market morganites are less traded in form of morganite beads but rather cut, faceted and marketed more as morganite gems.
