Santa Maria emerald-cut aquamarine held in tweezers
"Santa Maria" Emerald Cut
3.42 ct · VVS · Unheated
Origin: Brazil · GIT-AQ-3311
Featured Cut — 01

Cut for the Santa Maria colour.

This step-cut stone is faceted to hold the deepest, most saturated sea-blue our rough allows — the reference colour collectors call "Santa Maria," named after the Brazilian mine where it was first found.

Unheated, and graded VVS for exceptional transparency edge to edge.

Fan-cut oval aquamarine on a display tray
Fan-Cut Oval Aquamarine
18.40 ct · VS · Unheated
Origin: Brazil · GIT-AQ-3319
Featured Cut — 02

A fan of facets, cut into the pavilion.

Rather than standard brilliant faceting, this oval's pavilion is cut in a radiating fan pattern — an ornamental style that trades a little brilliance for a striking, one-of-a-kind look.

Large enough to anchor a serious pendant or cocktail ring.

Large statement cushion-cut aquamarine
Statement Cushion Aquamarine
24.15 ct · VS · Unheated
Origin: Mozambique · GIT-AQ-3320
Featured Cut — 03

Soft corners, serious carat weight.

Cushion's rounded corners are forgiving of small inclusions near the girdle, which is part of why it's become a favourite for larger, statement-size aquamarine centre stones.

Round brilliant-cut aquamarine gemstones
Round Brilliant
1.08 ct · VVS · Unheated
Origin: Madagascar · GIT-AQ-3313
Featured Cut — 04

Calibrated round brilliants, matched to size.

Sourcing & Craft

Every stone weighed and graded, by hand.

Bankok has cut and traded coloured gemstone for generations, and it's where every aquamarine in this catalogue is faceted, polished and graded — by hand, on old-style dop sticks and modern angle-locked faceting machines alike.

We buy rough directly from mining regions in Brazil, Nigeria, Madagascar and Mozambique, then cut to maximise the stone's natural sea-blue colour rather than chasing carat weight alone — and every finished piece is weighed and checked in-house before it goes to a lab for grading.

Services

What comes with every stone

Beyond loose gemstones, we take on cutting, evaluation and certification work for jewellers and collectors.

01

Cuttings

We cut special orders to a jeweller's own specification — non-standard shapes, calibrated sizes, and custom facet patterns on request.

02

Gemstone Evaluation

In-house assessment of value, colour, hardness and species for aquamarine and other beryl material you already hold.

03

Gemological Certification

Every stone over 1 carat can ship with a GIT (Gem and Jewelry Institute of Thailand) report confirming weight, measurements and treatment.
