Help me find this setting

[autumngems]

I saw this setting posted on in Colored Stones and want to find who makes or sells it. The person posting it said someone else had posted it here on RT so I hope I can find it. I know there is a knock-off sold on Ebay but I want the real thing.

I think it is from Singapore.

But can't get to the site now, seems to be some problem with the website.

EDT:
Further down the thread there are links to similar setting from US vendors, Knox and Israel Diamonds.
