Actually this type of LI is usually very uniform in color with a very subtle speckle pattern which you probably won't see until it's lapped and you're looking upclose.

These are probably all LIs, the one at the right is a similar type as Martin's LI.

I totally agree Piet, the one on the right look just like mine.Since im not quite done lapping where does this stone fall into the progression?
And since you have 5 of them are they all different ?

The two at the left are of the same type, they just look a little different. The two at the right are very similar but because I have and have seen more of both I'd say they are a different type. Both types are extremely hard, they have tiny flaking in chips and a similar shade of green.

I would also agree with LI. And also feel sorry for the soul who wants to lap it flat with minimum of nicks in the surface. it will be a big job. Be carefull with lapping do it slow with a lot of water or even running otherwise they tehd to overheat and flake as they expand. So far I did not have problem honing with these flakes but it certainly look nicer without.

wow great thread guys this was a good learning experience for me i didnt know that LI had two different appearance's

I really dont know if i will be able to remove and make it perfect would have to remove a lot of stone will see how it goes so far so good!!!
Unless somebody's got a better method then a diamond plate?

Lapidary grit in various grit sizes (eg 100, 180, 240, 320 - you can go up to 600 but for some reason 600 and above a bit harder to get hold of), water, flat hard surface (cast iron plate/thick glass/granite) and a lot of rubbing. Quicker than a diamond plate and you can make longer/wider sweeps. Just put a small mound of grit on the plate, pour on some water and go at it. Makes a lot of mess, though. You can always true-up with the diamond plate if you suspect that your surface wasn't flat enough or you have allowed a build-up under the hone that has resulted in a slight roll of the surface. Usually not necessary though if you are careful.

Neil

Interesting Neil sounds like you do a lot of lapping!!! Can anybody perhaps comment on the use of a LI? Pre-finisher? finisher?
compare to others?

Same as with CFs decent finisher.

Yes, very decent finisher.
