This is a new mineral to me and I haven’t had much success finding information about it but this is a Blue Chalcedony. This has a stunning coral formation and definitely gives sea vibes. This piece measures roughly 5.4cm long, 5.1cm wide & 3cm high.
 
This is a very delicate and fragile piece. It is expected some small pieces may break off during delivery, however this will be very well wrapped.
