Triangle Cut Through Marbled Necklace

I made the pendant myself and added all the findings myself too. The purple and blue clay are both subtly marbled and I cut out and inserted a blue marbled piece. I really like the effect. 
The chain has 4 links at the end so there is slight adjustability in length.
 
The chain is long approx. 48cm  
The pendant is approx. 3cmX3cm
