This vintage Jade cabochon ring in 18k setting is very beautiful. Both the stone and setting are very fine. It was a purchase from an estate in the US, and we do not know where it was made, the only mark inside is 18k. which does not lend to it being Japanese. Per them, it does date to the 1960s-1970s which seems appropriate. The stone is high quality- my pictures are too dark to really see this but please see the picture that shows the back- the best which identifies the clarity with the natural webbing and how the light shines through it. I will retake when there is some natural light available. This identifies it as either nephrite or jadeite. Hold it up to the light with a loupe if possible to see this. The four prong setting goes through the stone giving it an added extra design element. The setting is surrounded all the way around with an arabesque style design and leaves at either end. The band curves in small waves. The band is marked 14k amd very hard to see but with no other identifying marks. Both the stone and setting are in excellent condition with no scratching seen magnified to macro. A very finely made jade ring in 18k yellow gold.

ANTIQUE AND VINTAGE JADE:
They all have one thing in common they are mostly make from white-gold or silver and from green cabochons from very light to almost dark, the design often looks not very appealing. Actually for most people wearing them the important stuff is the protective and metaphysical property of it.
This is one of the reason why elder Chinese people wear them because of superstition. Jadeite is also a good material for it because the material is extremely hard, almost like a diamond which makes longevity natural and material used.
The genuine material consists of two variants, one is jadeite and the other is nephrite and both are available in a wide color spectrum most popular is green. It’s sometimes difficult to figure what is a fake and what is real, means people get cheated by dishonest dealers. Now take a 10x magnifying glass and check the material.
from Nephrite and Jadeite website
Jade is one of the oldest known stones, and history shows that it was mined as early as 6000 B.C. In China, it was considered “The Imperial Gem”, as it was used for burial suits and grave furnishings for kings and other members of imperial families. Jade cicadas were also placed on the tongue of the deceased, as it was believed this would prevent decomposition and help guard the chi of the deceased.
It was carved into many figurines and other objects, and was as revered in China at that time as we revere gold and diamonds here today. To the ancient Chinese, gold was valuable, but jade was invaluable.
Nephrite is softer than the natural jade stone. High purity and texture is produced in Hetian from Xinjiang. It has a glass - oil sheen like shades.
