I am looking for CryptoPatreons! 5 NFT with a physical opal available

I've been into crypto for over 10 years now, but I'm not someone interested in money, more in the tech. Although these days money might make it easier for me to work on my craft, I though of giving a go at these NFT for a Patreonage.
Buying one of the five available patronage comes with the picture opal, cut by my hands, and source for Australia. Possible to provide a GIA certificate of authenticity
