Ring Sizing (Don't know your size?)

We've got you covered!

Our no charge calibrated sizing kit (available US only) will help you learn your perfect size! Available with ring purchase only.

Orders outside USA see alternate method below.


Don't rely on DIY/at-home sizing methods. They are inaccurate.


Alternate method 

Get sized locally: Visit at least 2-3 jewelers to get sized- it should be free. Why 2-3? Because some jewelers use inaccurate sizing methods or uncalibrated ring sizers that give an incorrect size. Going to 2-3 jewelers (that give you the same size) will help ensure you get the correct ring size.

Important note if getting sized locally-when selecting your size, keep in mind that wide (9mm+) rings tend to fit more snugly. Consider increasing the size you order a little (1/4 to 1/2 size) if you're getting a wider (9mm+) ring. Feel free to contactme withany questions.

How wide should my ring be?

Most people choose between 6-8mm wide

3-4mm - Very narrow

This narrow is a more feminine look.


5mm - Slim

Rings in this width are less common for men's rings, though some prefer a narrower ring.


6mm - Classic width

6mm is a very traditional men's band width. If you're new to wearing rings, or like a more classic style, this is probably for you.


8mm - Modern width

8mm is a modern/contemporary width that is gaining popularity. A little wider than traditional wedding bands, it has more presence than 6mm, but is still comfortable for daily wear.


9mm+ Very wide

Rings this wide are uncommon and make a statement. If you're looking at something this wide, you probably already know what you want. If you're not used to wearing jewelry, a ring this wide might bother you.

Remember Very wide rings tend to fit more snugly. You might need to adjust the size you order if you're getting a wider (9mm+) ring.

 Tired of boring old rings? The ones in stores all kinda look the same right? That's because they're all mass produced for the "average person". Well, you're not average and I believe a wedding band shouldn't be something average either. This custom, handcrafted, super strong aerospace grade titanium band has been given an awesome matte black finish and a teak wood liner meticulously crafted and given a comfort fit and waterproof finish designed for long-term wear.

Custom Wedding Band

I'm so happy with the ring that was made for my fiancé! I swapped the teak for the bloodwood and it looks so good! Communication was easy and fast. So excited to slide this beautiful ring on his finger for good! :)

Quality meets style

Richter Scale rings is a gem of a find. My ring is well-crafted, exactly as pictured, and looks great. After showing a friend he immediately ordered one for himself. I highly recommend!

Beautiful ring

Fast turnaround, maker got it shipped within 10 days or so.

I was worried about the black finish getting scratched off when coming into contact with other metals and hard surfaces. And indeed it will get scratched, exposing the silver color of the titanium. However, within a day or two, the scratches seem to fade completely and are no longer visible to the naked eye. My guess is that this is caused by oxidization. Anyway, I'm very happy with the ring.
