Very detailed carving makes this a very elegant Burmese jadeite necklace.  The Burmese jadeite pendant part is 42mm wide, 23mm long and 3.5mm thick.  Both sides of the pendant are the same.  Two honey color jadeite beads hang from the pendant.  The pendant is attached to a "Dragon Whiskers" adjustable silk cord and includes two more jadeite accent beads.

Tested by refraction, genuine Burmese jadeite
