- 01 — The String
It begins with a single line.
Held under tension, it is the thread this story follows from first frame to last.
- 02 — Eight Strings
One string for every letter.
Each one drops to a weight of the Nexa typeface, from Black through Heavy, Extra-bold, Bold and Regular to Book.
- 03 — Formation
Weight becomes a spectrum.
A gentle transition in weights forms a spectrum within the typography, turning the wordmark into its own metaphor.
- 04 — From String to Light
The ‘E’ holds the light.
Its three bars move from red to violet: the two ends of the spectrum, and the full range of possibilities that exist in between.
- 05 — The Identity
Spectrum, complete.
Set in Nexa from Black to Book. In the full lockup, Stargems Group appears in Extra Bold for legacy and authority, and ‘A Company’ in Regular for clarity and balance.
Colour Signature
Ember, Core and Prism.
Three colours carry the spectrum from one end to the other, held in a calm field of glaze, eclipse and quartz greys. Tap a colour to copy its value.
The Spectrum
Step into a Spectrum of Possibilities.
Seven bands on one proportional scale. The first band is the base unit (x); each band after it grows, up to 7x. Equal centre-to-centre spacing keeps the system balanced at any height.
In the World
Shades of Excellence.
Stationery
Quiet paper, precise weight.
The wordmark and the band pattern carry the identity across cards and correspondence, from full colour to a single blind emboss.
From Origin to Opulence.
The brand line follows the stone itself, from rough to polished.
Out of Home
Scaled to the street.
Large formats let the rough stone and the spectrum E do the talking.
