Picked it up in an antique shop, just because the design of the ring. It's marked 18K with jeweler certificate. However the origin is still unknown. There is no certificate or guarantee for the jadeite stone. I personally believe it's a untreated genuine jadeite and it passed black light test(to identify filled jadeite). The diamonds were tested by a heat probe.
The photos were taken in direct sun light when the ring was dry and free of grease.
My best guess of the origin is Hong Kong. Anyone has a clue please help.
I'd like to quote an interesting jadeite ring from kyratango

Shrine! Glad to see you back :-)
The jade color is fantastic in your ring!
Is the back open, closed or with a "peeping hole" to see through the jade?
The mount is vintage, perhaps before all the grade B and C jade floods the market :-)
18k mark is more American than English (it would be 18ct), but I don't know if Hong-Kong marked gold with K...
Thank you for the link to my ring ;-)
Just found this:
"in arabic numerals clearly indicating in carats, by number or by number and the letters "k", "c" or "ct" the fineness of the gold content in accordance with the standards of fineness specified in the First Schedule;"

Thank you Kyratango for sharing your ideas in jewellery. Only the person with extensive knowledge with ring settings could ever ask whether the back of ring is open or closed. In my case, this ring is closed with solid gold at the back. So the perceptive hue of the jadeite could be altered a bit towards yellowish because of the highly reflective gold substrate.
I can't be more agree with you that the grade B and C jadeite flooded the market since 50s. However this ring doesn't look that old to me.
There were 2 sudden booms in jadeite export in past century. The first was 10-20s after the collapse of Qing Dynasty, when bankrupted aristocrats were forced to sell their treasure to western world. The second was early 80s when China eventually opened its door to the world and jade dealers from Hong Kong and South East Asia surged in for bargain hunting. If this jadeite was Grade A, it's likely to be from the second export boom. That's my two cents to make the guess.
Beautiful Green color:)
