Kira Cup

Just as gemstones such as diamonds gain brilliance through their own unique cuts,
The shape of this piece, which divides one square into four facets, was born from the pursuit of shadow effects that stand out on white porcelain.

Applied in platinum or gold, this form transforms into a shape of "brilliance" that reflects light.
This piece could be said to express Koga's concept of viewing ceramics as “jewels.”
