Blood Spots


The above bead is a newly created three eye dZi from Taiwan (less than 10 years old). It displays red blood spots (called Martik in Tibetan) which are natural iron inclusions inherent in the agate. Tibetans often look for blood spots to help distinguish ancient beads from the modern replicas, however, it is mistaken to believe that blood spots can only appear on ancient beads. Whilst it is rare to find blood spots appearing on new beads they certainly do exist.

Many new beads can also have 'brown' coloured inclusions that are often confused with blood spots, however, they are not always the same thing. Also, the red spots appearing on the above bead are clearly inherent within the stone and this means they have not been applied to the surface of the bead.

Many new beads have also been given artificial surface fissures/cracks which are coated in a red dye to give the appearance of age and blood spots (see the bead below). This is often called 'Dragon Veins' by Chinese sellers of new dZi. If you look closely at the bead below, you will also see that one of the holes has a build up of red dye. This is a clear sign that the dye was added after the bead was drilled and therefore not a natural occurrence.

This gives the appearance of red veins and is an
attempt to imitate the red blood spot inclusions
visible within some ancient dZi beads.

The bead shown below is a rare quality Taiwanese bead from the 1990s. This bead displays 'brown' inclusions which are very different from the 'red' spots that Tibetans look for when identifying ancient beads. It is possible these inclusions are simply the result of a chemical reaction between the decorated lines and the base colour during the heating of the stone.

often mistaken for 'red' blood spots. Whilst they are a little similar
in appearance they are not the same as blood spots.

in the crystalline zone.
