Vintage 24 carat pure yellow gold with "A" Jade “brilliant” green Jade stone. This is 100% Natural not treated Jade. The stone is an 8 mm oval. The ring size is: (8) and the 24 carat pure gold is marked 9999 with a Chinese maker’s mark next to it. (See photo). The weight of the ring is 12 grams/.38 ounce. The Jade is one of the best intense, neon emerald green color Jade I have seen. The Jade is translucent but because of the solid sheet of 24 carat gold, covering the back side of the ring, the only light allowed through the Jade stone comes from the front of the stone and it is translucent when the sun shines through it.
