This wooden ring is made of Kou- a Hawaiian wood that grows primarily on the coast of the islands. (fun fact: it produces buoyant fruit, so it falls in the ocean and washes up on other coasts, thus spreading its seeds) It is an uncommon wood, as it was nearly destroyed by a insect scourge in the 19th century. It is famous for its association with the royal family as well its more common uses as bowls and utensils. This stock is very dark, however it is streaked with beautiful golden patches that are like a tiger eye stone.

The outer portion of this ring is made of Cobalt - the most scratch resistant and shatterproof material I offer. Like titanium it is hypoallergenic and biocompatible. However, in many circumstances under which your Titanium ring might scratch, Cobalt will not. It is an alloy that is identical to Platinum in color, but it is an order of magnitude stronger. Cobalt offers nearly the scratch resistance of Tungsten Carbide, but unlike Tungsten, Cobalt will not shatter if dropped.

The ring pictured is a polished finish (default), but a satin finish is also available. The ring is also a domed profile (vs. a flat profile), which can also be changed. Just add the details you like in the appropriate section at checkout. 


I highly recommend going to a jewelry counter to determine your size, even if you believe 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.

The minimum width for this style is 5mm. The maximum is 8mm.
Recommended width is calculated in this way: Size 5 is 5mm wide. Width increases .5mm per size above that. So:

Size 5- 5mm
Size 6- 5.5mm
Size 7- 6mm
Size 8- 6.5mm
Size 9- 7mm
Size 10- 7.5mm
Size 11+ - 8mm
