Guide to Moldavite Grades
Collector quality, museum grade, A-grade, cutting grade... What do these terms really mean? Here's a clear guide to understanding what you're actually buying.
01Why Grades Cause Confusion
There are many grades of moldavite, developed over time based on the personal experience and preferences of sellers. This makes it easy to get confused about what is being described and what you are actually buying. Let's look at them from highest to lowest.
02Quality Levels
Highest Quality
Common names: Collector Quality, Special Pieces, Investor Grade, Museum Grade. Be aware, however: "museum grade" is an overused term, and most moldavite labeled as such is actually just good A-grade moldavite. The highest quality usually combines two or more factors that make it rare and desirable. The main ones are:
- Condition: minimal or no damage
- A primary shape (drop, disc, ellipsoid, sphere, hourglass) or beautiful, symmetrical shapes
- Larger size and weight: from approximately 2g to over 100g
- Remarkable surface sculpture, such as "hedgehog" (not mandatory)
- A rare locality (this alone is not enough to make it collectible)
- Rare characteristics such as an Angel Chime — an optional bonus
Superior Grade
Common names: Collector Grade or Museum Grade (often used improperly). Denotes special stones: primary shapes, extra-large sizes, or a combination of rare characteristics.
Good Quality
Common names: Grade A, AA, AAA, Premium, Superior. Means little to no visible damage. Can range from a beautiful undamaged stone over 50g to specimens of 1–4g.
Medium Quality
Common names: Grade B or Regular. More evident damage (chips, scratches, abrasions) from extraction, transport, or erosion: these appear as shiny spots where the glass reflects light.
Lower Quality
Common names: Cutting Grade or Damaged. Broken or heavily damaged stones, usually intended for faceted or carved jewelry.
03Three Myths Debunked
Myth 1 — "Darker moldavite is lower grade"
False. Brightness and darkness do not affect the grade: thicker pieces appear darker because they let less light through. It's just a matter of taste.
Myth 2 — "A higher grade has stronger energy"
False. There is no relationship between energy and grade: the system only serves to describe damage and rarity. All moldavite shares the same origin, whether it's a perfect 70g piece or a 1g fragment.
Myth 3 — "Museum moldavite is actually from a museum"
"Museum grade" is used very liberally: it almost always simply indicates good condition A-grade moldavite with minimal damage.
