Forbes Magazine places Grandidierite at No. 3 in its list of the most expensive gemstones and it will often feature near the top if you google, 'rarest gemstones'.

Grandidierite is pricey and it is rare but with a bit of searching and a bit of haggling there are some real bargains to be found in this delicious looking gemstone.

Grandidierite Colors

Grandidierite is a blue-green gemstone which is probably best described as 'teal'. Any example which steers more towards blue is even more rare and therefore more expensive. The color is the result of the presence of iron.

Faceted Grandidierite gemstones can appear to change color as they are turned from one angle to another, displaying dark blue-green, blue, colorless, yellow and green colors in a phenomenon known as pleochroism.

Grandidierite Species

Grandidierite is a rarely found mineral that was first discovered in 1902 in Madagascar and since then a very few other locations around the world. It is a silicate made up of mostly magnesium, aluminum and boron with iron deposits creating the color.

If the mineral itself is considered quite rare, transparent or translucent examples good enough to be turned into gemstones are rarer still.

What are the spiritual benefits of Grandidierite?

Being an uncommon and relatively recently discovered gemstone, Grandidierite has not built up much of a reputation for its healing or spiritual powers however it has strengths through its color and mineral ingredients.

Benefits include:

  • A Great Meditation Stone
  • Helps Decision Making
  • Improves Relationships
  • Boosts Immune System

Grandidierite and the Chakras

The Chakras are centers of spiritual power situated around the body in specific locations. Each Chakra point has a name and an associated color. Gemstones of a similar color can be used to unblock or realign a troubled Chakra.

With is green-blue teal color, Grandidierite can be linked to two Chakras – the Heart and the Throat. Placing a Grandidierite gemstone on the center of the chest or the small of the throat can directly influence these Chakras.

Grandidierite Price

Like most gemstones, the first thing to affect the price of Grandidierite is the color. All Grandidierites must be a shade of blue-green to hold any real value and the more blue the color the more expensive they will become.

Once the color is established we have clarity. A clear, flawless Grandidierite with a nice teal tone will be a very expensive gemstone indeed. More translucent examples with the right coloring can still be impressive gemstones, especially when shaped into cabochons with flat bottoms and rounded tops.

Carat Weight

Grandidierite gemstones get more expensive per carat in various ways:

  • Bluer gemstones are rarer than green stones
  • Clear examples are harder to find than translucent gems
  • Large carat weights come in more limited quantities than smaller stones.

Add these factors together and we can come up with a rough price guide:

  • Clear gems under 1 carat - $30 - $300 per carat
  • Clear gems 1 - 10 carat - $40 - $1200 per carat
  • Clear gems over 10 carat - $40 - $2000 per carat
  • Translucent gems under 1 carat - $20 - $250 per carat
  • Translucent gems 1 - 10 carat - $25 - $300 per carat
  • Translucent gems over 10 carat - $30 - $500 per carat
