Anglesite Values and Pricing

When valuing Anglesite you’ll need to break up the pricing into two distinct groups. For gemstone collectors, you can expect to pay $20.00 to $100.00 per carat. Most of the faceted stones will be colorless or have a faint yellow tint to them. More than likely you won’t see faceted stones on a regular basis but you will see crystal clusters. If you’re a specimen collector then you should expect to pay $55.00 to $500.00 per specimen depending on the size and overall rarity.

Anglesite can be sourced in colorless and slightly yellow-to-yellow crystals. The commercial availability of this gemstone is low which means you’ll need to source your faceted gemstone from a gem dealer or visit a local gem and mineral show in your area.

The main sources of high-quality Anglesite come from Morocco, Namibia, and Idaho.

How to determine value and cost

When determining the value of the gemstone you will be using GIA guidelines which means color, clarity, carat weight, and cut.  You’ll want to look at each one of these individually and then circle back when finished to evaluate the stone as a whole.

Color is going to be the most important factor when determining the value of gemstones.  Clarity and carat weight are tied for the second most important factor.

Before you go any further you need to ensure you have identified Anglesite correctly.


Color – The more intense the color the more valuable the stone is.  When dealing with warm colors, think of red and orange, you’ll want to determine if there are brown undertones.  If you can’t see brown undertones then the color should be very vibrant.  The more vibrant and saturated the color the more expensive the gemstone.  If the gemstone has a unique “neon-like glow” then it will demand the highest price per carat.

With Anglesite you’ll be judging how “colorless” the stone is and its overall brightness. You want to see a nice, bright stone but it will probably have a yellowish tint.


Clarity – Buyers, and collectors prefer stones with no internal inclusions visible to the eye. Anglesite can be found with visible inclusions all the way to flawless.  To determine the clarity ranking you’ll need at a minimum a 10x loop and a higher-powered microscope to confirm internally flawless and flawless designations.

If you can visibly see the inclusion while holding the gemstone then the highest designation would be SI1 and if the inclusion detracts from the overall beauty of the stone then the clarity designation would be I1 – I3.

Clarity designations – FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, I3


Gemstone clarity scale


Carat – Anglesite can be found in sizes ranging from below 1 carat to above 10 carats.  Generally speaking, Anglesite can be sourced in most carat weights. The larger stones with high clarity will bring a higher price per carat due to rarity.


Cut – It is sad to say but cut has the least impact on value and cost unless it affects the stone in an extreme way.  For example, when you look at the stone you would be able to see through it which means light is not being reflected back to the eye.  This is called a window in the stone and it would have to be quite large to impact the price.  The other extreme would occur when you look at a stone and see a rough circle or oval shape inside the stone.  This occurs when the stone is very shallow and it’s reflecting the rough girdle inside the stone.  Note: the girdle is the edge/side of the stone where the pavilion and crown meet.

How valuable is Anglesite?

Anglesite has never brought a higher dollar per carat because the demand for a colorless stone with high dispersion but a low score on the Moh’s hardness scale just isn’t there. Collectors and gemstone enthusiasts will buy and cut Anglesite but the mass appeal of this stone will always be limited due to how soft it is.


Values of Anglesite will not increase over time

Each year I do research on market prices for Anglesite and prices for small to mid-sized stones are fairly constant. If I was looking to add Anglesite to my collection then I would try to source crystal clusters with larger crystals mixed in with smaller crystals.

If you’re not sure how to value a gemstone then you should consider a gemstone appraisal. Individuals acquiring gemstones through inheritance, estate sales, and auctions typically have the gemstone appraised to determine the value and to ensure the gem is what they think it is.
