Sapphire by Aung

Every fine sapphire starts here.

A green sapphire rough, before craftsmanship brings it to life.

Sapphire by Aung - from rough to brilliance.

Before the brilliance begins.
Each Sapphire is carefully preformed into intended shape before precision cutting. A process that defines the stone's natural character and future sparkle.

From rough to radiance, every detail matters.

Before & After Heating - Yellow Sapphire

At Sapphire by Aung, we use precise heating to enhance each sapphire's natural color and clarity.

Before heating, the tone may appear cloudy. After heating, the color stabilizes into a vivid, transparent golden.

Mr.Aung specializes in precision grading, evaluating color tone, clarity, and proportion to ensure every sapphire meets international standards before polishing and setting.

Accuracy isn't just skill, it's discipline built through decades of experience.
