Archive Calibration Guide

The Biomechanics of Fit

Aura Brilliant archives feature a precision Comfort-Fit domed interior. This allows the monolithic metal to slide smoothly and adapt to the natural volumetric fluctuations of your tissue.

Primary Protocol: Inner Diameter

DIAMETER

The Tension Rule: Flesh compresses; tungsten does not. For absolute precision, measure the inner diameter of an existing ring that fits perfectly and match it below.

US Size	Diameter (mm)	Circumference
7	17.3	54.4
8	18.1	56.9
9	18.9	59.5
10	19.8	62.1
11	20.6	64.6
12	21.4	67.2
13	22.2	69.7

Secondary Protocol: Paper Calibration

If you do not have an existing ring, download our 1:1 printable calibration strip.

Download PDF Sizer (US Letter)

Critical Execution: Apply Firm Tension.

Paper does not stretch. Ensure the strip is pulled tightly across the knuckle to simulate metal compression, or it will read 1 size too large.

The 8mm Profile Logic: Given our substantial width, if your diameter measurement falls strictly between two sizes, we recommend selecting the next whole size up.

Absolute Fit Guarantee We engineer resilience, not friction. Should your initial calibration be less than absolute, we provide a complimentary re-calibration piece—no return of the original is required.

Variant

The Causal Inscription (Optional)

ARCHIVE PROTOCOL: Structural artifacts modified with a Causal Inscription are permanently locked. The 14-Day Alignment Window is void. All inscribed items are final sale.

○ Free US Shipping | All Taxes Included

○ 14-Day Alignment Window

○ Secure Encrypted Checkout

○ Lifetime Resilience Support

Core Integrity: High-Performance Technical Zirconia. A non-metallic, polycrystalline archive engineered for extreme thermal stability and impact resistance.
Weight Signature: A lightweight technical alternative ( $6.0\ g/cm^3$ ), providing a "silent" tactile experience for the navigator who demands agility without compromising strength.
Surface Absolute: Obsidian mirror-polish with permanent scratch resistance ( $Mohs\ 8.5+$ ). Non-conductive, non-magnetic, and 100% biocompatible.
Integrity: The deep black pigment is inherent to the molecular structure—it will never fade, tarnish, or oxidize under any environmental stress.

The Meaning

The Obsidian Prism captures the essence of absolute clarity within the void. Inspired by the sharp geometry of natural obsidian, it is engineered to act as a prism for the spirit—filtering external noise into singular, focused intent. Unlike the heavy anchors of our tungsten series, the Prism offers weightless resilience. It is a wearable bastion for the navigator who moves with silent precision, carrying a core of darkness that reflects an unyielding inner light.

Archive Logs / Structural Feedback

Nathaniel Thorne ■ VERIFIED ACQUISITION

"The density of this piece is remarkable. The meteorite etching feels raw and ancient against the precision of the gold line."

Marcus A. ■ VERIFIED ACQUISITION

"Minimalist but heavy. The sandblasted finish has a tactical feel that doesn't pick up fingerprints or scratches during gym sessions."

Julian R. Blackwood ■ VERIFIED ACQUISITION

"Unscrewing the 106g vault was an experience in itself. The ring inside carries that same precision-engineered weight."

Julian V. ■ VERIFIED ACQUISITION

"The gold stripes are incredibly sharp and disciplined. It lacks the gaudiness of typical jewelry and feels like a precision-engineered tool. Perfectly balanced."

Sebastian H. Cruz ■ VERIFIED ACQUISITION

"Unexpectedly tough for something with pearl. The structural depth of the inlay is far better than the studio photos suggest."

The Aura Ceremony

Every monolithic archive is housed within a $59 Structural Vault, included at no additional cost as part of the initial acquisition ceremony.
