When "frost wedging" occurs due to water freezing in cracks in rocks what is the most pressure the freezing water can exert on the sides of the crack as its volume expands by 9 Diabase diorite gabbro. According to the Goldich chart quartz the most resistant mineral to weathering and it is the last mineral to crystalize as very

Is Jade tougher than diamond Mvorganizing

 · The mix of these two minerals makes jade the toughest gemstone in nature and even though nephrite and jadeite are relatively easy to scratch and softer than diamond their resistance to chipping is extremely high. Diamond is the highest gemstone on the hardness scale in nature but can be broken by a hard blow.

Gabbrodiabase

A distinctive feature of the stone is a high level of hardness strength of 1400 kg / cm 2 this quality guarantees its resistance to loads. Water absorption of gabbrodiabase is the stone is almost 100 moisture resistant. It does not collect water which guarantees its resistance not only to frost but also to sudden temperature changes.
