SUWA rubies are highly transparent and beautiful, defect-free heat-treated Gem Quality stones from Myanmar (90%) and Mozambique (10%). The color is close to a nearly pure red with no orange or purplish tones, and when combined, they give off a beautiful, unified presence.
For small-sized rubies, SUWA uses Gem Quality material with Tones of 4 to 5 and Beauty Grades of S to A.
