Geodes are highly valued for their content and appearance. The most valuable geodes are those that contain perfectly formed flawless crystals of amethyst, celestine, calcite, or other rare minerals. Geodes are worth from $2-5 for common specimens and up to several thousand for exceptional several meters.
Geodes are formed when there are pockets of air within rocks. This often happens after volcanic eruptions when lava cools around air bubbles. These pockets leave space for groundwater to seep in. But the water itself doesn't produce geodes–it brings along minerals which stay in the rock even after the water evaporates.
Tell-Tale Signs of a Geode
Geodes are found all over the world, though they are most concentrated in desert regions. Other places where geodes are common are volcanic ash beds and areas containing limestone. There are geode collecting sites all over the U.S. in California, Utah, Arizona, Nevada, and Iowa.

Typically, geodes do not have gold or diamonds in them. The type of rock formations usually associated with gold is quartz, and with diamonds its kimberlite. Geodes are known to contain gems called Herkimer diamonds, Bristol Diamonds as well as Gold aura quartz, but they are not real gold or diamonds.
While not particularly common, there are some select locations in New York where geodes have reportedly been found. The best place to find geodes in New York State is the town of Fowler, in local stream beds and sedimentary exposures. These geodes usually contain barite or hematite crystals.
Almandine is an iron alumina garnet, of deep red color, inclining to purple. It is frequently cut with a convex face, or en cabochon, and is then known as carbuncle.
Quartz crystal is found in many countries and many geologic environments. Major producers of natural quartz crystals are the United States (particularly Arkansas) and Brazil. Natural quartz is rarely used as found in nature (especially in electrical applications), except as a gemstone.
A Herkimer diamond is worth about $1600 for water-clear, 4mm round faceted diamond. Herkimer diamond's value is determined by the above 4Cs. Generally speaking, prices can range depending on craftsmanship and the quality of the gemstone.
Herkimer diamonds are not actually diamonds at all. They are a form of double-terminated quartz crystals that began forming 500 million years ago in the dolomite outcrops throughout Herkimer County, New Year and the Mohawk River Valley.
What are Herkimer Diamonds? Herkimer Diamonds are beautiful double-terminated quartz crystals found in Herkimer, New York. Incredibly, these phenomenal gemstones are close to five hundred million years old. The crystals are magnificent works of nature, found in the rock, having a diamond-like geometrical shape.
Quartz's clarity earns it a raw price of around $0.01/carat and a gem price of $1-$7/carat. Amethyst, or purple quartz, is the most valuable variety (can reach $15/carat), but pink, rose, and smokey quartz is also valuable. Clearer, more vibrant, and unbroken specimens are the most valuable quartz.
For a gem which was once regarded as precious as Sapphire, Amethyst is very affordable, even at the higher grades. Prices for high quality cut stones are typically in the range of $20 to $30 per carat, with particularly fine pieces around $40 per carat.
Clearly, rose quartz is not a rare find. GemPundit lists it for about $3.50 per carat. Despite its abundance, rose quartz is divided into categories of quality, including heirloom, best, better and good.
Typically with amethyst, the labor that goes into faceting the stone is going to represent the bulk of the price of the cut gemstone. For some price context, faceted amethyst gemstones from India may sell for as little as $2 per carat where some of the material with better color from brazil will sell for $5-10/caret.
How Much Is The Peridot Worth? In general, the Peridot price ranges approximately $50-$80 USD for the average size of 1 carat. The finest quality, top-color Peridots that are larger than 1 carat range steeper in price at $400-$450 USD.
Description. Citrine Rough Points. Citrine is a vibrant yellow form of quartz, and many of these tumbled stones look just like crystalized rays of sunshine. Known as 'The Merchant Stone,” citrine is perhaps one of the most powerful stone to work with for manifesting financial prosperity and abundance.
Musgravite. Musgravite was discovered in 1967 and is arguably the rarest gemstone in the world. It was first discovered in Musgrave Ranges, Australia, and later found in Madagascar and Greenland.
