Unfortunately this is impossible to authenticate in the absence of an authenticity tag. I suspect (but cannot say for sure) that there may be an RFID chip embedded into the BV stamped patch. Bottega has done buyers a real disservice by making these bags so easily faked. Although I guess they probably don’t really care - they want you to buy direct from them.
I will say that the roughness of the Intrecciato has no bearing on authenticity. A lot of calfskin bags have that very slight imperfect edge of the fettuce.
I would be very leery of anyone who can claim to authenticate newer models like this that don’t have an authenticity tag. If I were you, you could take your bag into a boutique, feign innocence and ask them if they can tell you what colour your bag is, since you *forgot*

Good luck
