Yes it is two corals that grow together. Say two chalices that both have ok color. Now once they grow together they start to swirling colors. A good graphed coral will keep the colors after a frag is taken. A lot of times to many people have grafted corals not allowing them to swirl together to get into the DNA of the coral. The result is a cool looking frag that just reverts to one of the original Ungrafted corals. Hope this makes sense. Look up each name of a grafted coral that has generations of frags that have been grown out.
