Libyan Desert Glass
Libyan Desert Glass
Additional inventory added 18 February 2013
News flash! A possible source crater for Libyan Desert Glass has been discovered (March, 2006 announcement). The Kebira Crater is more than 20 times the diameter of Meteor Crater, Arizona. It was discovered by Farouk El-Baz, director of the Boston University Center for Remote Sensing. You can see it by going to Google Earth and flying to the following coordinates: 24°40'23.66"N, 24°57'32.03"E. The crater is located about 100 km from the center of the Libyan Desert Glass strewn field, and was blasted into Nubian Sandstone, long considered an excellent compositional match for LDG. There is still some controversy about this discovery, and the lack of flight-related morphology in any LDG is a worry. On this basis, I have to join the skeptics----
|Since Libyan Desert Glass is found in Egypt (albeit an exceedingly remote part!),
we have often been asked whether any has been found in Egyptian tombs. We finally have an answer: YES! In King
Tut's tomb no less! The image of King Tut's breastplate at left shows a carved straw- yellow scarab as its centerpiece.
Long assumed to be chalcedony, this has now been confirmed to be Libyan Desert Glass!
I have not been able to determine the whereabouts of this artifact. After multiple trips to the Egyptian National Museum, I am quite sure it is not on display there, nor is there any indication where it may be on loan (as is clearly marked for lots of other King Tut material on temporary loan).
|Before we leave the subject of cultural history, I should also mention that the Libyan Desert Glass strewn field quite frequently yields LDG artifacts. They are virtually always simple blades struck from cores by percussion. I have only seen one showing secondary pressure flaking. Such blades make effective cutting instruments, and the earliest agriculturalists sometimes lined up a row of blades in a piece of curved, slotted wood to form scythes for grain harvest. We have just acquired a small lot of fine Libyan Desert Glass blades. The small image at the left can also be clicked for a blowup (close that window when you're done to return to this page) and a bunch of these are offered for sale near the bottom of this page.|
UPDATED 2/28/2012) to eliminate sold items and add heaps of new inventory.
A comment regarding color: Libyan Desert Glass appearance varies greatly with lighting conditions. In the sunlight of its homeland, there is a slightly different wavelength mix than at higher or lower latitudes. In its native setting, LDG has hints of neon apple green whereas in my area (Spokane, Washington, USA), it is more of a straw yellow. Whiter colors are due to abundant bubble inclusions (exactly like pulled taffy candy that goes from clear sugar syrup to opaque as bubbles are worked into it). The brown to gray streaks are said to be of a composition suggesting included stony meteorite dust. Some pieces have tiny white spherules of cristobalite that result from devitrification. Due to artifical lighting employed in many of the photos below, there is a darker amber yellow tint than you will see in natural light. Think of pale straw yellow as a base color, with white and brown variants due to bubbles and meteoritic dust inclusions.
A comment regarding pricing and quality: We scour the world for the very best quality pieces available. With few exceptions, the pieces we offer are unusually gemmy and free of recent chips or damage. We refuse to deal with suppliers that have not taken good care of their specimens. (Some Ebay sellers have big stuff at very low prices. It is often photographed wet so you won't see the glassy chips from a 1000 km ride in a bucket in the back of a 4WD. This is a mortal sin, not worthy of your support). We pick the best of the best, piece by piece, and pay whatever it takes to get the real winners. I average my purchase costs all out when determining price, and I can honestly tell you that some of these pieces are priced cheaper than what I paid for them individually wholesale. If you want to get an idea of my quality assessment, work out the asking price per gram. Under $3/gm is material that I am reluctant to sell at all, as it does not meet our quality standards (we only get an occasional piece of this grade by mistake----). Most top-end material falls in the $3 to $6/gm range, and a few super special pieces may push $10/gm.
In our price structure, assume that $1.50 to $2.00/gm is average "run of mine" material. If you spent a few thousand dollars to go into the Libyan desert and picked up every piece you saw, this would be the grade for maybe 80% of it. $3/gm is above average, but mostly not offered here. At $4/gm, these will be very gemmy and/or otherwise special pieces, probably in the top 5% quality range. At $4.50 to $6/gm, you are looking at specimens that I don't much care whether they sell or not. I'd be perfectly happy to keep them myself. Above $6/gm, you can bet you are looking at museum pieces. I do attach a premium to bigger pieces, so small specimens at $3/gm may represent very nice quality. It is obviously easier to preserve a small gemmy chip than a big lunker of the same quality.
Since the supply side on this material has dwindled to a trickle and recent reports indicate that expeditions into the source area are either not permitted at all or, at minimum, require that you pay for an Egyptian military escort, AND since the supply is obviously limited and finite and increasingly picked over in ANY case, really good pieces can go nowhere but up. Listed below, you will find the largest selection of QUALITY pieces available in the world today. Prices may change at any time. Those posted at the date of your firm order will be respected. Since we have such a superb array of specimens on hand, we now only buy 20 or 30 new pieces per year. These are carefully selected as the very best available from assortments of many hundreds to thousands of pieces. If you see "2013" in the item number, this is an item that was cherry-picked this year, the best of the best. We're always very selective and picky, but these represent extreme selection. We simply don't buy it if we don't love it. If we buy and offer it to you, you can count on this being some of the finest material to be had anywhere!.
Other terminology:chatoyance, devitrification, chondrite dust, ventifact, debitage (definitions to be added soon)

|168.0 gms of sculpted iceberg glory. My all time favorite!||I may refuse to sell this one. The only circumstance I can imagine in which I would sell is if it were to a very, very loving home! If you're the one, price doesn't matter. If you're not the one, no worries. $1500.00 (#LDG1680)|
|96.4 gms||Subtle interlayering of clear and bubble-inclusion rich layers. Beautiful piece, displays well. $385|
68.8 gms; half highly transparent, half milky with planar bands of tiny bubbles.
|Another flawless beaut. Nicely sculpted by the wind-blown sands of the desert.$300 (#LDG688)|
|64.6 gms. Side View of a very neat display piece!||A very nice 64.6 gm chunk that stands like an iceberg! Cheaply priced at $175. (#LDG646)|
|58.4 gms||A very pleasing piece with beautiful sculpted form and high polish. $240|
|58.3 gms||Delicate curtains of oriented flattened bubbles give this ventifact a silky chatoyance. $225|
|57.5 gms. Deep fluting!||This one has unusually sharp and deep parallel fluting. Very ornate. $225|
|53.2 gms. Glorious sculpture!||Interesting moderately milky interior due to finely dispersed bubbles. Some dark chondritic dust inclusions visible. The crowning glory of this piece is its wonderful all-over pitting, ventifacting, and polish, like melted ice! $215 (#LDG532)|
|51.3 gms. Much nicer than the picture shows----||Great overall sculpture with planar internal bubble-rich layering and deep external fluting. Good polish on all surfaces. $185 (#LDG513)Sold|
A big one at 49.9 gms with excellent transparency, full of cristobalite spherules!
|An exceptionally beautiful specimen with abundant small hemispheric pits. The value is compounded by the special combination of lots of obvious white cristobalite devitrification spherulites and the highly transparent matrix that allows them to be seen. A real winner! $320SOLD (#LDG499)|
|48.1 gms. Milky, resembling paraffin wax.||I mostly select for gemmy clarity, but this one is such an unusual semi-opaque and quite uniform milky color that we had to have it. $170|
|45.4 gms. Gemmy with deeply sculpted concavities||An unusually deeply 3-dimensional piece, hard to adequatedly capture in a 2-D photo. (#LDG2012_0454) $175|
|44.5 gms. Excellent chatoyance!||Viewed from some directions, this piece is typical straw yellow and quite transparent. But rotate it, and it becomes silky white and semi-opaque. (Think of fiber optics spheres. It's similar to that). $175|
|44.4 gms. Very ornate sculpture||This has a flat base and a very convoluted top, with deep pits and grooves. Nice. $180|
|44.0 gms. Ventifact||Interesting wind facets. Quite clear with curtains of white bubbles. $150|
|39.5 gms. Very gemmy with a large internal chamber open to one end.||Spectacular skin ornamentation. Glossy all over. A natural bottle! The creamy colored internal area visible in the photo is the cavity, still filted with desert dust. This could be cleaned out and literally used as a bottle to contain something special. I am guessing that the capacity might be in the range of 5 to 10 drops. (#LDG2012_0395) $300|
|38.8 gms. Flawless ventifact, a very comforting worry-stone!||A totally gorgeous piece covered with smooth thumb-print facets. If you know how pleasing some LDG is to hold and
feel, this one is amazing in that way. Shaped and polished by the desert winds, this is a superb example of its
type. (#LDG2012_0388) $
|37.5 gms Relatively flat||Greasy-luster, dimpled surface, lots of bubble inclusions. $110|

30.6 gms. Thin, transparent, and packed with cristobalite!
|A fantastic 30.6 gm specimen selected for it's fine display of white cristobalite devitrification spherulites. The front surface is a smoothly curved, wind-polished conchoidal fracture face that provides a great window into the interior. Great display piece. $195 (#LDG306)|

|26.0 gms. Glossy, pure ventifact.||Very glossy, gemmy piece, like pale straw-colored jelly. (#LDG2012_0260) $175|

|24.4 gms. Ornate fine pitting.||Sharp morphology and a finely dimpled skin make this an unusual specimen. $85 (#LDG244)|
|23.9 gms. Fine geometry||Abundant dark chondritic dust whisps create a greenish tint. Tiny cristobalite spherules are apparent. (#LDG2012_0239) $170|
