This material This material is made much like Damascus steel - layers of different grades of Ti are folded together and etched. Not with acid like steel and NOT anodized like other colored Ti or aluminum. With extreme heat.  This causes the titanium to form colored oxidized layers at different rates.

This coloration is more durable than anodized, but is expected to scratch and wear at the same rate as any other titanium ring.

This is the absolute highest grade Koa you will see. The wood for these rings have been selected for its old-grown, chatoyant figure. Koa is known for its "curl," and this is a CURLY piece. It is very difficult to capture in pictures.  This stock has been vacuum stabilized green acrylic.  This process is an art form in itself, as only certain stock is appropriate for this expensive, complex procedure.  I was doing some research so that I could describe the effect. I will just quote from a top google result because I cannot improve on this description: 

"Chatoyancy is a property that is usually attributed to certain gems, the cats eye effect or shimmer which gives a senseof depth in the gem. This property can also be used to describe some of the more dramatic pieces of curly, tigerstripe and fiddleback Koa. This figuring gives the wood a three dimensional quality; and depending on from what angle one views the wood, it can take on several completely different characters."*

It is a uniquely Hawaiian wood, and is one of the most prized natural products from the islands. 

Comfort Fit.
