Multiple stones on one ring

[Sage37]

This might be a stupid question but I’m still new to jewellery and interested to learn. I have come across a style of ring which I love and was wondering what the technique is to make setting like this? I imagine this is probably manufactured or an advanced setting, but just interested to know so I can hopefully make my way up to making items like this! Any info or advice is appreciated. Thanks so much!

It's probably 3D printed in wax, or resin, and cast,
You could make a low tech version, by adding tube collets to a strip, which is about 1,0mm too short, forming a ring, and then stretching it a tiny bit to size it. Then perfect the collets.

By being cautious like that, you could minimise any distortion due to stretching. It would need a ring stretcher, which is applied internally, and to totally avoid hammers. Dennis.
