Sir I want to ask about the carrier of diamonds asides to kimberlites...is there a possible that silicates are also the host of diamonds? I have different types of natural diamonds in my possession and I bought these in Papua New Guinea from the people living in mountainous area.Some of stones are grayish-blue and pinky white colours with inclusions of different types like graphite and white bubbles.I want to ask if GIA is the only agency for scientific research to discover and to de-zipper the history of our planet earth by means of evaluating the gemstone.Thanks.
