Balance of Size / Diamonds / Round Cuts

The round-cut diamonds that SUWA uses are carefully polished from "sawable" rough, highly transparent octahedrons that are shaped like two pyramids joined at the base.

For round diamonds under 1.5 mm in diameter, SUWA uses single-cuts. Their larger facets make them sparkle more beautifully than brilliant-cuts.

Balance of Shape / Diamonds / Marquise Cut

The cutter's goal is to minimize the loss of weight from the rough when polishing,
resulting in various shapes of marquise cuts.

Diamonds / Marquise Cut

SUWA uses marquise-cut diamonds that have beautiful outlines with a length-to-width ratio of 2:1.

Balance of Color / The Color of Gemstones and the Color of Precious Metals

SUWA selects a setting of the precious metal that will bring out the maximum beauty of a gemstone's color.

For the warm red of rubies and green of emeralds, yellow gold is used, and for the cool blue color of sapphire, platinum is used.
