Determining Demantoid Garnet Value

Is Demantoid Garnet valuable? The value of colored stones is typically determined by a combination of its color, clarity, cut, and carat weight. This is no different when determining what Demantoid Garnet is worth. These guidelines will help you choose garnet stones for your collection.

  • Demantoid Garnet Color

The color of Demantoid Garnet ranges from intense green to yellow-green. It brilliantly reminds us of new spring grass. The presence of chromium creates the green hue in Demantoid Garnet. In some specimens, ferric iron may add traces of yellow. Also, light dispersion is high, so its flashes of rainbow color can be noticeable, especially in lighter-colored stones.

  • Demantoid Garnet Clarity

Demantoid Garnet is a transparent gemstone with vitreous to resinous luster. It belongs to the Type II category of GIA clarity grading system, which implies that the stone contains inclusions. Under the microscope, it displays inclusions that are known as "horsetails." They are wisps of long, golden, fiber-like inclusions that radiate from a central point. These delicate wisps are quite beautiful and can increase the value of the gem.

However, a large amount of inclusions decreases the value of the Demantoid Garnet gemstone, chiefly when it affects the color.

  • Demantoid Garnet Cut

Due to limited availability and small size of the gemstone, Demantoid Garnet is available in limited shapes. Cuts such as round, oval, and pear are widespread. They are typically faceted to maximize the brilliance of the stone. Cutters must carefully position these gems so that the stone displays the best face-up color.

  • Demantoid Garnet Carat

The standard size of Demantoid Garnet stones from Shop LC start around three millimeters in round shapes, with oval jewels going up to roughly 7x5 mm. Carat weight of finished stones ranges from approximately 20 points to 2.5 carats.

The price per carat tends to increase dramatically with larger stones. Demantoid Garnet in higher carat weights is simply rare to find and therefore command higher prices.

Where Does Demantoid Garnet Come From?

Demantoid Garnet occurs in mines near Ambanja City, Madagascar. The area is a famous mining locality, well-known around the world for producing sapphires and garnets. This unique blend of garnet isn't known to occur anywhere else in the world.

DUnfortunately, irregular mining practices have kept the supply entering the market limited for many years. Since October 2009, authorities have brought the situation under control. At times, however, the area is still considered dangerous.

How is Demantoid Garnet Mined?

The Demantoid Garnet deposits exist in the Ant Sira Nana region of Northern Madagascar, 2.5 kilometers west of the village of Antetezambato. Deposits feature isolated and broken crystals of Demantoid Garnet and gemstone bearing skarn veins, between fractures of sandstone and limestone rocks.

Most of the mining takes place within a mangrove swamp that is subject to daily tidal flooding. Open pits are drilled and dug 5 to 20 meters deep to reach the gemstone deposits. Small-scale mining and large-scale operations have become very difficult and unproductive, mostly because of the daily tidal flooding.

Since April 2010 the extraction of this gemstone has diminished. Mainly because of the difficulty and danger of continued mining as seawater infiltrates the pits and tunnels during high tide.

Currently, the tunnels reach a depth of no more than 5–20 meters. It is reasonable to speculate that workers are reaching only a small percentage of the total deposit. Vast reserves of Demantoid Garnet are possible at other areas of the deposit, as most of the garnet-rich veins dip steeply and occur over an area of several hectares.
