This wood ring is the absolute highest grade Koa you will see in a wooden ring. It has a gorgeous deep golden color and unbelievable curl. Koa is known for its "curl," and this is a CURLY piece. It is very difficult to capture in pictures. 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. 

Unlike the other styles of rings in this shop, "channel" type rings will always have a seam in the wood. It will be visible, but hard to detect 9 inches or so away, and completely invisible at any distance. I have made no effort to hide the seam in these pictures. If you have difficulty finding it, it is because it is subtle.

The titanium liner is 6al-4v grade 5 titanium, preferred among jewelers. 


Titanium ring sizes run from 4 to 16 including quarter sizes. I highly recommend going to a jewelry counter to determine your size, even if you already know your size. "Do it yourself" ring sizing methods (string, etc.) should absolutely not be trusted. Be sure to be measured using the width you plan to order. 

NOTE ON WIDTH:

The minimum width for this style of ring is 4mm. The maximum is 8mm.

Recommended width is calculated in this way: Size 5 is 5mm wide. Width increases .5mm per full size above that. 

Sizes 4-9 will have .5mm of titanium on each side of the wood. Sizes 9.25+ will have 1mm.

So:

Size 5- 5mm - 4mm wood stripe
Size 7- 6mm - 5mm wood stripe
Size 9- 7mm - 6mm wood stripe
Size 10- 7.5mm - 5.5mm wood stripe
Size 11- 8mm - 6mm wood stripe

Titanium lined wood rings cannot be resized at all! Every ring is made to the exact size provided. An error in sizing that exceeds the margin provided above will necessitate a completely new ring. Refunds and exchanges will not be possible.

Each ring is given multiple coats of a hybrid epoxy finish, which is completely water-proof and soap proof. This protective coating is sanded up to 12,000 grit for an unbelievable, glass-like finish.

All rings ship via USPS Priority (or Priority International) Small Flat Rate Box.  You pay what I pay for shipping, nothing more.

For customers outside the US:
International customers are responsible for all fees associated with shipping to their respective countries. Orders that are shipped to countries outside of the United States may be subject to import taxes, customs duties and fees levied by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are levied once a shipment reaches your country. Additional charges for customs clearance must be borne by the recipient; I have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; you should contact your local customs office for further information. When customs clearance procedures are required, it can cause delays beyond the original delivery estimates. It is against the law and I will not mark an item as a "gift" to avoid any fees.
