Lets see some impressive handle material.

Ivory is intriguing to me. Love the variety. I don't know the exact minerals, but iron is the main culprit behind the colors. The black ivory is from brownish-black organic soil. The brownish-orangish ivory is from more iron-rich sandy/gravely soil. The vivianite, an iron phosphate, is whitish/gray in its unoxidized condition. Vivianite turns blue when oxidized.
Ivory has around 20% excess moisture when it is excavated. That is why curing is so important before its use as handle material. Cured and finished properly, movement shouldn't become a serious problem on a knife.
Maybe Doug will find out some more information on this cool handle material.

You sure about that Doug? I alway understood that gold is one element that doesn't break down when exposed to acids. Exposing it to acid is one of the old ways of checking its purity.

That's an old way to test gold K and still used by some.

By placing a drop of acid on the gold, then rub against a hard surface (generally another stone) and the deepness of the color of the residue that rubs off on the stone determines the content.

Hey RogerP, whose this one by?
 
Here are a couple of interesting rock handles. One is dendretic agate, the other sugilite.
 
While pearl is often used with folders, I have a few knives with pearl that are FB's including this integral by DF Kressler engraved by David Perdue

Bob Crowder does quite a bit of work with pearl as these two will attest

the first is like the 2007 MKA club knife and the bird/trout knife is engraved by Bruce Shaw

another DPH this time by Mike Franklin (in his pre HAWG days) with titanium bolsters

Jim Ence created this fine example using extremely thick pearl scales and pearl rosettes

Wolfegang Loerchner used BLP and Martin Butler engraving in this semi mini piece

great thread with lots of wonderful knives to look at using a multitude of handle materials.
 
Some premium pearl on two knives by Dellana from my collection.
She has developed an amazimg technique to embed gold drops and
diamonds in gold bezel settings onto the pearl.....

Showing such knives in a small picture does not convey the beauty
and amazing workmanship involved....

I think that a detail shown close-up will better illustrate the quality
of Dellana's work. Before her knifemaking days she was considered
a world-class jewelery maker. She learnt to forge her own Damascus from
the great Jim Schmidt and her knives are true sole-authorship art....
