Sizing Guide
Precision is paramount.
We recognize that securing the perfect fit is critical to the integrity of your overall aesthetic.
This guide is structured to provide the exact insight and guidance required to determine your true size with absolute confidence before securing your piece.
Ring
Overview
Our selections follow standard US sizing specifications. Because our bands feature a substantial profile, securing the correct inner circumference is vital.
Use the Inner Circumference metrics below to determine your fit.

Wrap a string or measuring tape around the base of your finger, mark the overlap, and measure the length in millimeters to match our sizing chart.
Option C

If you already own a ring that fits your target finger perfectly, order that exact size.

Sizes?
Size down only if your actual finger measurement is slightly bigger than the size measurement. Otherwise, we highly recommend sizing up. Because our rings are engineered from solid, unyielding titanium, a slightly larger fit ensures comfort during natural finger swelling and allows the ring to clear the knuckle without restriction.
Bracelet
Overview
AVAILABLE LENGTHS:
7.5" (19cm) / 8.0" (20.5cm) / 8.5" (22cm)
Do not purchase a bracelet that matches your exact wrist measurement, as the heavy metal requires room for movement. Add an inch to your baseline wrist measurement to find your optimal range and refer to the chart below for best sizing option.

Fit Preference
- Flush Fit: If you are at the top of a sizing range, the bracelet will sit flush against your wrist with minimal movement.
- Relaxed Fit: If you prefer movement or "drape" in your daily rotation, select the next size up.

Wrap a measuring tape tight around your wrist bone, mark the overlap with no gap, and match your wrist size to the optimal range.
Necklace
Overview
AVAILABLE LENGTHS:
20" (50cm) / 22" (55cm)
Chain length determines "Stance"—where the metal sits relative to your collarbone and clothing neckline. Therefore, necklace length is a personal preference based on where you want the chain to sit.

| Length Option | Stance | Visual Reference |
|---|---|---|
| 20" (50 cm) | STRUCTURED FIT | Sits at the collarbone. At or slightly below a crew-neck t-shirt. A controlled, sharper look. |
| 22" (55 cm) | LOW DROP | Sits below the collarbone / top of sternum. Falls about an inch under a crew-neck line. Relaxed and fluid. |
Body Build
Variable
Variable
Neck structure and body build may vary the fit and dictate the necklace profile.
LEAN / STANDARD BUILD:
• A 20" (50cm) chain sits comfortably at or slightly below the collarbone.
• A 22" (55cm) chain hangs freely mid-chest, about an inch below the collarbone.
HEAVY / ATHLETIC BUILD (Thicker Neck/ Traps):
• A 20" (50cm) chain will sit higher and tighter against the neck, potentially above the collarbone.
*Consider sizing up for optimal drape • A 22" (55cm) chain is highly recommended for broader builds, as it will rest naturally at or slightly below the collarbone.

Cut a string to exactly 50cm or 55cm. Drape it around your neck in front of a mirror to check the stance relative to your favorite t-shirt neckline before making your selection.
