I believe almost all true Nephrite Jade aficionados were effectively ‘hooked’ by the “Stone of Heaven” through a singular event; a single encounter with a particular piece of stone. For me it was at a very early age (somewhere in the neighborhood of 7 years old) in a barn in the Mid-West where I saw my first ‘treasure’, a carving stuck between two bales of hay at a good old farm auction. It sure was green, and it sure was beautiful, with all the intricate little people, trees, animals and tiny houses, and even though the auction house put it up on the block after my discovery, and asking if “this was going to be for sale”, it sure didn’t end up meeting my budget by the time the gavel hit. But hooked I was, or perhaps smitten would be a better word, as no matter where life would take me after that, I never forgot that beautiful piece of stone and the wonderful carving on it. Whether it was really Jade or just a green stone, and whether it was truly masterfully carved or just a nice little WWII tourist item, all I really can say is that 50 years later, I am still fascinated by jade, and fascinated by carving and artistry of all types, but particularly Chinese, like that first ‘greenstone’ carving I lost the bid on so many years ago. (I did end up buying at that auction a little carved greenstone fish that I will always swear was my first piece of jade, even if it wasn’t 
.
This tremendous example of gem-quality “Polar” Nephrite Jade was donated to us by Mr. Kirk Makepeace of Jade West & Jade Mine, out of his personal, private collection of specimens, for a series of articles in which we can continue to discuss some of the different qualities and characteristics of one of the world’s most fascinating and truly glorious (and also misunderstood) stones. In this series of articles, we are going to examine one of the most beautiful nephrite jades ever discovered, and compare it to several other extremely unique types of nephrite. We will study it by way of structure, texture, durability and carvability; but in luster and sheer beauty it will be extremely hard to find any nephrite that stands so high. The series will end some months from now (as I do run a full-time business with interests in jade and art), with a finished, polished carving, in which I hope to come close to fulfilling the potential of this marvelous specimen.

When the worlds finest Jade Carving Artists, Geologists, Mine Owners, Geophysicists, Artifact Specialists, Rare Specimen Traders, and just plain old aficionados of Nephrite and Jadeite gather at the few venues dedicated to support this marvelous stone, certain common-use terms float about the conversations for hours, or days at a time. At shows like the Big Sur Jade Festival and the Jade Art Now Show, with each particular specimen or jade carving comes talk from all walks of life about each stone’s particular color and structure. Words like opacity, translucence, chatoyancy, ‘cream’, ’cheese’, jadeitite, texture, snowflake, flowing, ‘tight’, ‘flaky’, associated minerals, and hundreds more are just commonplace terms bandied about and not given much thought among those that have made the differing jades such an important part of their lives. In this one unique specimen called ‘Polar’, we find all that is written and talked about in the Stone of Heaven. It is perhaps the most representative sample of what nephrite truly is that I have ever run across, and to me it means “Jade in All Its Glory”. Preferences in the business vary, from certain types of nephrite because of their particular needs in carving, to the colors that fascinate them (like the purity and tightness of Edwards Black and certain Olive Wyoming stones), to the unique qualities of some of the famous New Zealand Jades and those from Australia, British Columbia, Siberia, the different Jades from California, and indeed all over the world. All that is expressed and felt about the different types of Nephrite Jades is meaningful and true to those passionate individuals who hold their beliefs, but concerning everyone I have ever seen who prefers a certain stone like the beautiful blues of the California coast and other places, I have never seen anyone pass by a piece of Polar Jade, not stop and, half in awe, make an exclamation of beauty, or simply mutter to themselves under their breath something like, ”simply stunning”. So now, just for the sake of this article, we will again put up the first picture to discuss the overall qualities.
Here we can see the awesome translucency that shows along the left edge of the picture, under just the regular photography lights. We can see the unique yellowish/green contrasts that come from the marriage of the Iron and the Chromium, but rather than the chromium garnets we find in say, Cassiar nephrite, the mix of the two metals is much more homogeneous in a fine piece of Polar, and tends to give an ‘ethereal’ glow to the stone. We still find areas (spots) of heavier Chromium concentrations that show up as the brilliant yellowish flakes we see in this picture, and later you will get to see under magnification the complexities that make up these unique portions. Also to be seen in this specimen, if looking closely, are the associated metals in the tiny black spots of Magnetite. However, to me, the strangest formations that take place in Polar are the fairly total, translucent white areas that are so much like the finest Khotan translucent white nephrite that has been revered for millennia, mixed and swirled in with the unique cloudy actinolite fibrous areas we see, looking like cirrus clouds intermixing through a sky of green in an ‘otherworldly’ pattern found in no other nephrite I know of, to this degree. In my opinion, if this Polar Jade had been known to the great Qing Dynasty carvers from China in the late 1850′s era, we would have seen the more popular Siberian Apple Green masterpieces replaced, and relegated to a secondary status by this, a far superior stone with an inherently much more magnificent feel.

This close up of the above stone shows in great detail the ‘swirling cloud’ effect that is so unique to Polar Jade, and while this close up ‘washes out’ a bit of the intense yellow/green color, it can still be seen where the light penetrates the stone on the left side of the photo. Also, to be seen are the little specks of Magnetite, showing up as small black dots over and inside the nephrite. While these Magnetite intrusions are similar to those found in Siberian Jades, they have a much different pattern on the whole, and show up more irregularly in the Polar, while they seem much more homogeneous in the Siberian samples we have examined. This is not to say one is better because of this placement, but it helps simplify identification for the less experienced collector. Just as not all Polar jade is exactly the same, neither is the Siberian or other jades displaying these Magnetite specks, and by examining enough specimens from known sources, one starts to get a fairly good feel for the placement of a stone to the area from which it could have come from, by knowing some of the varying anomalies that occur in each area. Also, while sometimes we must speak in generalities concerning stone from differing areas, it should be noted here that some of the Siberian gem-quality stone is extremely fine and displays many of the characteristics we will be discussing in this article, but as of this date we have not seen a large piece of Siberian nephrite that even comes close to showing all the extremely unique characteristics found in this one piece of Polar jade. This is not to say that a piece of similar nephrite does not exist out there somewhere, or that a stone will not be found that has all of these extremely important characteristics of a “true stand-alone type”, but to date we know of no other nephrite that is quite like this exquisite stone, which came from a deposit that was so prolific and produced such quality.

Another fine photo, again showing from a different viewpoint, some of the unique structural properties of Polar Jade in just a small close-up section of the stone. The fine translucence is clearly visible toward the right edge of the slab, proximal to the outside rind. In this area we can see how a small, clear, white, translucent section goes all the way through this particular area to the rind on the other side. More of the cloudy, fibrous, and chatoyant swirling shows up in great detail, melding with the greener portions at this level, but will disappear when we get past the Macro lens photos and into the microscopic photos. The Magnetite ‘specks’ are more concentrated on the outside edges of this specimen, but can be found deeper in the stone, as will be shown in some of the Macro lens and microscopic pictures. The highly unusual white “flakes” that one often sees in “snowflake” specimens will also reveal that they are not typical snowflake sections, but rather, are a formation unique to this particular stone, and as yet, are an unknown (to us) type of structure and mineralization. This will be very clear in the coming microscopic pictures.

The two photos above show approximately the same area, but with differences in the Macro lens being set at only 1X power and the second photo at only 2X. The clear translucent area, with its cloud-like formations in this wonderful piece of Polar Jade, runs its entire length of approximately five inches, and clear through the slab that ranges from a negative edge to approximately one and a half inches in width. In the first picture, the cirrus cloud-like nature appears to be more of a surface effect on the Nephrite, but we can clearly see in photograph 2 that with the penetration of the Macro lens, the ’clouds’ actually show thoughout the stone in differing levels. This gives the jade a strong sense of depth and ’feel’, as one rolls the piece over in one’s hands. In the sunlight, it bestows the piece with a subtle glow of deep, translucent water green and a presence of water-like, flowing motion. Under the light in ‘house’ conditions, the entire color of the stone changes to one of deep emerald green with literally waves of motion in the translucent portions, and bright green specks where the ‘snowflake’ effect occurs. The difference in the sizes of the minuscule Magnetite particles, deeper in the ‘body of the jade, is accentuated greatly by the change from the 1x to the 2x Magnification of the Macro lens. This also accounts for difference in color seen in both photos. Both colors are true to the amount of light and magnification received.

The above photograph taken under only 20X Magnification starts to show the cirrus cloud-like formations in the translucent area starting to disappear, while the true color of the Chromium and Iron mix of yellow/green begins to show up more. The Magnetite crystalline formations begin to show up as more than mere ‘specks’, and we can begin the see the structural qualities of the snowflake anomalies that occur thoughout certain portions of the stone. One can start to see the snowflake patterns not as fractures in the stone (although there are a few small fractures that are natural or are due to the mining process), but almost as what one one could describe as ‘growths’ within the nephrite. While the whitened areas do start to take on a fibrous look at this power, and almost appear as a ‘mutton fat’ nephrite formed inside this stone, it is doubtful to us that this would be the case. In a nephritic stone such as this, there would seem to be just too high a mineral contamination for a solid, pure white nephrite to form. Not to say it can never occur, as one will sometimes see in Khotan Jade from Turkanistan just such a definite transition; but that is the point. The pieces we see coming from the White and Black Jade Rivers region, while oftentimes having such transitional colors (and many old nephrite artifacts of the archaic period were clearly chosen for this flowing transitional color effect), show their color ranges more on a linear, flowing development (much as with the flowing transitional zones in this piece), and not in the spotted manner we see here with this piece of Polar Jade. We think it would be a good study for someone like the GIA to examine these types of areas, and determine conclusively if it is nephritic in nature or something different. Perhaps a pseudomorph type of transition is occurring, or there truly are other types of crystalline growths occurring within the nephrites.

The above photo was chosen just to show the awesome beauty of color that is so typical of what one finds in the most ‘emerald’ portions of Polar Jade. Taken close to the cross fracture from mining (as can be seen in photograph 2) this photograph shows a minor fracture on the polished skin on one side of the stone. The slight fracture is just refracting the light from the microscope and allowing us to see clearly the transitional zones of color. Magnetite crystals and minor white growths mentioned in the above paragraph can also be seen under the surface layer.

This wonderful photograph shows certain aspects of Polar Jade at their finest. The translucence and true depth of color become evident at the higher power used in this shot. The Magnetite crystals are even clearer, and the white growth spoken of previously can now be seen almost like coral under water. Another piece of Magnetite lies deeper inside the stone beneath the white growth. The tightness of grain in the fibrous nature of this specific type of nephrite starts to become extremely obvious in the lack of fibers showing at 35X . It is an extremely tightly-fibered piece of nephrite, as will be seen in additional photographs at higher magnifications.

At 40X magnification, we can start to see the nephritic fibers in this particular stone. Usually it quite easy to detect these nephritic fibers at powers as low as 10X to 20X, but here we have a very translucent stone and very small and tight fibers. It should be noted that the more opaque the stone, the easier it is to see the nephritic fibers. Some opaque jades like Wyoming Edwards Black and some of the olives, along with the famous Cowell Black discovered in Australia in 1972, are obvious exceptions to this rule. It really boils down to us that some jades, even from the same general area, are not at all the same but rather are so obviously different that this still puzzles us; why we find so little useful information in this area ever having been published. Our planned article on the different structures found in jades of the Khotan area will be a fine article to illustrate just how diverse nephrite jade truly is, even in a fairly generalized area.
Above Photos Taken with Canon EOS XSi Using 90X Microscopic Power
The above two photographs precisely show the fibrous nephritic nature of Kirk Makepeace’s Jade West/Jade Mine’s Polar Jade at 90X microscopic power. It has always amazed me that the best-known, and extemely copied, high-resolution photographs of both nephrite and jadeite are false color images, when it has long been within the scope of photography and geology to render true life photographs of both types of stones and show their real nature. While there have been many articles written about Mr. Makepeace and all of his adventures in the World of Jade, we want this series of articles, from polished specimen to finished carving, to stand alone as a testimony to the unique beauty and fascinating characteristics of this phenomenal stone. Currently, it is our understanding that no more of this particular material is available from the Polar Mine; however, other fascinating jades are still being mined and marketed by Jade Mine. But who knows what lies around the next bend? We are sure that Mr. Makepeace will indeed be peering around that bend.
