Color is good, how long ago has this bud graft been done. Once new growth has flushed, you'll have confirmation.

First picture looks like rock formation. I remember a similar picture you showed us 2 years ago. The graft looks fine, even growing that one horizontal.

Second picture looks a lot better, that one will take of big time.

The graft is 19 days old. Both pictures are of the same one of 2 grafts. The other graft was green but crisp.

The bud is between the lines. I removed the white grafting tape and replaced it with clear grafting tape to hold in moisture while giving the bud some light.

I wish cell phones took clear macro shots. I take too many blurs. Not everyone is into selfies!

Herman you can try a hand lens cell phone combo but you have hold them separately and adjust the distance. It takes a good bit of fiddling to get a hang of it. Or get an attachment for your phone. But they are expensive.
