Natural Diamond Engagement

Formed by earth,
set for a lifetime.

A private edit of natural diamond engagement rings — each stone vetted at our downtown Boise studio and set by hand into the designs that arrive here.

Origin

A billion years in the making.

Every stone here is a natural diamond — grown deep in the earth over geologic time and sourced through vetted, conflict- free channels.

Certification

Independent laboratory reports 

Center stones arrive with non-biased outside laboratory reports. We'll walk you through cut, color, clarity, and carat in plain language — no pressure, no pun intended.

Bespoke

Or design something only yours.

Don't see the one? Shape it yourself in our 3D ring builder, or reserve a concierge appointment and we'll hand-source a stone and build the setting around it.

The Standard

Natural Diamond Details

Sourcing, cut, and certification — the three pillars that separate an extraordinary natural diamond from one that simply looks good on paper.

Stone Sourcing

Earth-formed. Responsibly recovered.

Every natural diamond here was created under the earth's crust over one to three billion years. We source through vetted, conflict-free channels that meet Kimberley Process standards and align with our own ethical expectations. When available, we prioritize stones with documented provenance and full traceability from mine to cutter.

Conflict-free & traceable

Cut Quality

Cut is what makes a diamond come alive.

A diamond's cut determines how light returns to the eye. We evaluate proportions, symmetry, and polish beyond the grade on paper — because two stones with the same certificate can perform very differently. We only select diamonds with crisp brilliance, balanced fire, and a lively presence across natural daylight and studio lighting.

Hand-selected for light performance

Certification

Verified by independent laboratories.

Center stones arrive with grading reports from GIA, IGI, or other recognized gemological labs. During your appointment, we translate the report into plain language — cut, color, clarity, carat, fluorescence, and proportions — so you can choose with confidence and compare stones on what actually matters to you.

Questions

Natural diamonds, answered.

Sourcing, certification, and care — the details that matter when you are choosing a stone that will be worn for a lifetime.

Natural diamonds were formed deep within the earth under immense heat and pressure over one to three billion years. They are mined, cut, and polished — not manufactured in a laboratory. Every natural diamond in our studio is earth-formed and carries its own unique internal fingerprint, which is documented on its independent laboratory report.

Concierge

Prefer to be walked through it?

Reserve an appointment at our downtown Boise studio. We'll pull a selection of natural diamonds to your specifications and, if nothing feels right, source one specifically for you.
