Karelian Birch, so named after the region between Finland and Russia, is also known as Masur Birch.  Masur birch is not a species, but any birch with a certain look - curly, and with interesting black squiggle figure.  Do not mistake it for burl. This phenomenon is unique to birch and highly sought after for veneer, knife handles, and other small turnings.

The metal in this listing is Black Zirconium-- Zirconium that is heat treated until it attains a very hard, durable black coating. The naturally silver colored metal is placed in a kiln at very high temperatures until the extreme heat causes oxidization. Just for full disclosure - the metal ring really is a very dark grey. The ring pictured is a satin finish, but a polished finishes 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 at checkout.

Sizing

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 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
