5 tips to check for Akro oxblood
1. Is the red transparent or translucent? If it is, its not Akro Oxblood.
2. Take a pen light and point it directly into the red...does it glow? If it does, its not Akro Oxblood.
3. Look very closely at the red...does it have small black filaments in it almost opaque looking? If it is, it may be Akro Oxblood.
4. Akro Oxblood is usually on the surface, although there are some rare examples where the Oxblood goes below the surface, or is sometimes completely inside a marble.
5. If you have never held a true Akro Oxblood in your hands and you think you have one, you probably don't! Once you have seen one, you will know what to compare it to. I would suggest getting to your nearest marble show and get a look at one in hand if possible. If not - maybe a trusted collector will sell or trade one with you for ID purposes.
