This is a favorite of mine! So. Get it before I do! ;-) bright red/pink with light green outline.  A yummy yummy shape. It has a slight hairy striated pattern more pronounced on back! Is it the back? Hard for me to decide! If I set it for you I could make 2 sided   Fairly high dome at the center eye flat back w a bit of a undercut at saddle in stone
