Ferguson, the stone in this hilt is probably serpentine.
Jade, both nephrite and jadeite, has a hardness of 6.5 to 7 on the mohs scale. Serpentine has a hardness of 2.5 to 5.5. Both nephrite and jadeite come in a wide variety of colours, for instance I have a khanjar with a black stone hilt that has been identified as jade (I am uncertain if jadeite or nephrite) by an gemologist. I have a ring in which the stone is a large piece of lilac jadeite. You really need a gemologist to identify what the stone is, but a quick test that can save money when buying is to pull out your pocket knife and see if you can scratch the material. If you cannot scratch it, its a good indication that you have one of the jades in your hand. Over the years I have owned a number of daggers of this type, all have had serpentine hilts. |

I can scratch it. Probably serpentine.
Here's a pic of Bowenite Serpentine from wikipedia. Looks a lot like mine. Thanks gentlemen! Steve ![]() |

Just tried the stone at the bolster. It can scratch too.

Serpentine can go as high as 5.5 mohs, which is not all that far behind jade,but a sharp blade will still mark it.
A sharp blade will never mark jade, it just slides across the surface and leaves a deposit of steel, which looks like a very faint pencil mark. |

Alan is right. Jade (jadite and nephrite) are very hard stones, therefore difficult to carve, and will not be scratched by steel.

Even though it's not jade, I'm extremely happy with the knife. Though I can scratch the stone (with a very sharp, very hard S30V blade) it is pretty hard. It has survived all these years with no breakage, and is just a gorgeous material. I was very fortunate. The seller was asking $100, and I got it for much less.

It is the serpentine most frequently encountered in carving and jewellery." From http://www.cst.cmich.edu/users/dietr1rv/serpentine.htm "H. typically 2½ -4, but up to 5½ for some varieties, such as bowenite" Last edited by Ferguson; 16th August 2010 at 02:22 AM. |
