I. Material Science & Metallurgy

What defines the Structural Integrity of an Aura Brilliant archive?

Every archive is engineered from high-density, aerospace-grade material: Mohs 9.0 hardness Tungsten Carbide at 15.6 g/cm³ Absolute Density, and hand-forged Damascus steel produced through Causal Stratigraphy. Structural Integrity is not a marketing term — it is a measured combination of hardness, density, and resistance to deformation under daily load.

Is the 18K Gold solid, or a coating?

Neither term is precise. We use a Vacuum Ion-Deposition Interface (industry term: PVD, Physical Vapor Deposition) — a molecular ionic bonding process conducted in a vacuum environment that fuses 18K gold to the Core Matrix at a cellular level. This produces a bond significantly harder and more durable than standard electroplating, without the fragility of a solid-gold structural band at this density.

How is the Damascus pattern achieved, and how is it verified?

The pattern is the result of Causal Stratigraphy: hand-forged folding of the raw metal matrix, followed by deep acid-etching that exposes the internal structural layers. This is not a laser-engraved surface imitation — the pattern runs through the entire matrix, so it cannot be replicated by surface treatment alone.

II. Wear Mechanics & Environmental Resistance

Why do Tungsten archives carry a heavier weight signature?

15.6 g/cm³ Absolute Density is a deliberate engineering choice, not a byproduct. The mass provides constant tactile feedback — a physical grounding anchor rather than a decorative accessory that disappears on the hand.

Are meteorite and wood inlays resistant to water and environmental exposure?

Yes. All inlays are synthetically stabilized and vacuum-sealed within an industrial clear-coat matrix, protecting them from moisture ingress and material degradation over time.

Are the structural bands hypoallergenic?

Aerospace-grade Tungsten and the Vacuum Ion-Deposition Interface surface are both hypoallergenic. For sensitive skin, we also offer High-Performance Technical Zirconia (Ceramic) at 6.0 g/cm³ — a lighter-weight, non-conductive, fully hypoallergenic alternative to the Tungsten Core Matrix.

Will the Vacuum Ion-Deposition Interface wear off over time?

The molecular bond is engineered to significantly outperform standard electroplating under daily friction. Avoid contact with industrial abrasives to preserve the ionic interface. Gradual finish evolution over years of wear is addressed under the Aura Resilience Guarantee — see Returns & Resilience Protocol.

III. Usage, Sizing & Longevity

Can these structural bands be resized?

No — not by traditional heat-based jeweler methods. The Mohs 9.0 hardness that makes the Core Matrix nearly indestructible also makes it structurally resistant to resizing. This is why sizing is handled through the Complimentary Archive Exchange rather than in-house resizing: see the Structural Band Calibration Guide before ordering, and the Returns & Resilience Protocol if an exchange is needed after delivery.

IV. Logistics & Compliance

Are duties and import taxes included for US customers?

Yes. Aura Brilliant operates on a DDP (Delivered Duty Paid) model. All listed prices include comprehensive US import taxes and customs duties — there is no separate charge at delivery.

What is the typical delivery time to the United States?

Most archives arrive within 5–10 business days, depending on the complexity of the specific material batch and final inspection requirements.
