Gemstone Grading
At Otter Spirit, we use a simple grading system:
- AAA Grade – Our highest grade. These stones are nearly flawless, with deep, vibrant color and little to no visible inclusions.
- AA Grade – Excellent quality gemstones with great color, very few inclusions and some slight variation in hue.
- A Grade – Good quality stones that may show some visible inclusions and subtle color differences between beads.
100% Natural: our gemstones are never synthetic and never dyed. Some stones may be heat-treated (a common, permanent enhancement used to bring out natural beauty) — if so, we’ll always mention it explicitly.
Origin Transparency: we partner with trusted suppliers and share each gemstone’s country of origin whenever possible — because where your stones come from matters.
