The MR3 is for a buddy to complete his rainbow. The Tulip sapphire is for me to complete my onyx rainbow 🌈

Cardsmiths currency S1 #25 Tulip Diamond 1/1??

Anyone know the whereabouts of the S1 #25 Tulip Diamond 1/1?? I have the Onyx rainbow and have been searching for it the past 3 years. Nobody is stepping up in the subreddit so i am turning to here. Cardsmiths said it has been given to someone back during the S1 diamond exchange program so the hunt continues. Any leads would be greatly appreciated!!!
