House Architecture Style Question

For all my wonderful followers out there, I have a quick question please. Does anyone recognize this diamond style? Most of the decoration had deteriorated and disappeared. It appears that it was used to decorate all around the house. Just curious as to what it's called.



The abandoned farm house is located in Bacon County, Georgia. Very unusual looking, I thought. It's quite old.

I hope everyone is having a good Sunday.

Thanks! :))
