The Spirit of the Motagua

One river. Three thousand years.

In the valley of the Motagua, in eastern Guatemala, lies the jade of the Americas. The Olmec knew it. The Maya revered it. For four centuries the world forgot where it came from. Every Aratama stone begins here.

The earth

Born of pressure.

Jadeite forms where the ocean floor is drawn beneath a continent: immense pressure, and little heat. Along the Motagua fault, where the North American and Caribbean plates meet, it rose from the deep with the serpentine that carried it. Some of it is more than a hundred million years old.

The ancients

The colour of life.

For the Olmec and the Maya, jade held the green of water and young maize: breath, growth, life itself. It was worn by rulers and offered to the gods. A bead of jade was placed in the mouth of the dead, to carry the breath onward. The jadeite of ancient Mesoamerica came from this valley.

The silence

Lost, and found again.

After the conquest, the source fell silent, and for four centuries no one knew where the jade of the Maya had come from. In 1975 its ancient workings were found again in the Motagua valley, with the tools of Maya craftsmen still at the source. In 1998 the rains of Hurricane Mitch washed blue jade from the hills, and the lost source of the Olmec came to light.

The art

Five grades. From the rough to the connoisseur.

01Grade One

The Rough

What a gem is, how crystals grow, and why jade is a rock of countless interlocking crystals rather than a single one.

02Grade Two

Identification

Hardness, refractive index, specific gravity and the spectrum: the tests that separate jade from its many imitators.

03Grade Three

Grading & Value

Colour, translucency and texture; the treatments (Type A, B and C) and why disclosure decides the price.

04Grade Four

The Cut

Reading the rough, and the cabochon: the cut that suits jade best.

05Grade Five

The Connoisseur

Lab reports, appraisal, ethical sourcing, and buying and selling with a working gemologist’s judgement.

Three questions

Every collector asks them.

The three questions every collector asks: Is it real? What is it worth? Can I trust it?

Jade must be cut before it becomes a vessel; a person must learn before knowing the way.
