At Velarvide, we exclusively use natural gemstones — never synthetic, hydrothermal, lab-grown, glass-filled, dyed, or imitation materials unless specified.
Every stone is hand-selected for its clarity, color, natural luster, and structural integrity.

To help you clearly understand the quality of our gemstones, we follow a proprietary grading system with six levels:

A-、A、3A、5A、7A、7A+
This system evaluates gemstones from clarity, internal inclusions (cotton), cracks, transparency, color saturation, and overall brilliance.

Gemstone Quality Grades

Grade	Clarity	Transparency	Cracks	Rarity
A-	Visible inclusions & cotton	Semi-opaque	May show micro-cracks	Common
A	Moderate inclusions	Translucent	Fewer visible cracks	Common
3A	Mild inclusions	Translucent to semi-transparent	Minor structural flaws	Less common
5A	Very few inclusions	Transparent	Almost no cracks	Rare
7A	Near-clean	Highly transparent	No visible cracks	Very rare
7A+	Eye-clean / museum grade	Crystal-clear (top 0.1%)	No imperfections	Extremely rare
