Green Beryl Emerald. Beryl is the Crystal Family of Emerald and Aquamarine and the gorgeous pink Morganite. (There is also a white translucent Beryl used in jewellery, namely Goshenite, a yellow Beryl called Heliodor, and a very rare red Beryl given the oddball name of Bixbite.)
When Beryl is green it is due to the presence of a tiny amount of Chromium in the crystal, and that makes it Emerald.
The Green Beryl Emerald beads in the above bracelet are of native cut, handcut in an approximate button shape, reasonably uniform in size, then tumble-polished for smoothness. Green Beryl Emerald beads such as these, of the same sort of colour and cut, was a commonplace in the jewellery collections of the princely families of India, the gemstone sourced from points various in India and Pakistan and Afghanistan.

The three blue Sapphire beads, of Thailand origin, are also native-cut, in an oval shape, tumble-polished and machine-drilled.
The eight pleasingly baroque Pearls are of Chinese origin, of fine well-matched white lustre.
The Sapphire and Green Beryl Emerald beads in the above bracelet were fashioned in Jaipur, Rajasthan, and have been machine-drilled, making for a cleaner threading hole.
