Moldavite Grading & Quality
There is no official grading standard. Dealer labels like "AAA" or "museum grade" mean different things to different sellers, so learn the underlying features.
Common trade grades
| Grade | What it usually means |
|---|---|
| Chips / commercial | Broken or plain pieces, little etching; used for jewelry and wire wrapping |
| Regular | Whole stones with moderate texture and decent color |
| High / AA–AAA | Strong etching, attractive shape, good translucency |
| Museum | Exceptional, intact pieces with deep etching and classic shapes |
| Collector / sculpture | Rare forms, unusual shapes or famous localities; priced individually |
What drives value
Etching & texture
Deep, sharp, natural sculpting ("hedgehog", ruffled, feathery) is the single biggest quality factor.
Shape
Drops, discs, splash forms and "angel chime" shapes carry premiums. Broken edges reduce value.
Color & translucency
Rich bottle-to-forest green with good light transmission is preferred.
Locality
Besednice is the top premium; see Localities.
Size
Large intact quality pieces are rare and valuable; large plain pieces are cheap per gram.
Condition
Fresh fractures, chips and polishing on a raw piece lower value.
Raw vs cut
Faceted and cabochon Moldavite show color and clarity, but the cutting removes the natural surface. Collectors usually prize raw specimens; jewelry buyers often prefer cut stones. Cut pieces are also easier to fake convincingly.
