Natural diamonds often exist in the Kimberlite pipes of the mantle, where often contain the inorganic elements--- sulfur. So the inclusions of natural diamonds are always carbonate minerals and sulfide. Undoubtedly, the study of the additive sulfur action in the course of synthesizing diamond will further our understanding the reason of natural germ formation.

天然金刚石多产生于地壳中的金伯利岩和钾镁煌斑岩，该岩层中含有非金属元素硫，天然金刚石中的包裹体通常为硅酸盐矿物和硫化物[41]，因此研究添加剂硫在合成金刚石中的影响是认识天然金刚石成因的重要方面。
