A combination of smoky quartz and white feldspar forms the matrix of this specimen. Emplaced on the matrix are smoky quartz crystals, to 1 cm in length; and splendent, black schorls to 2.0 cm across . The essentially vertical aqua crystals, to 3.0 cm in length stand up from that pedestal. The aquas are glassy and gemmy with a rich blue color and transparent terminations. Very 3-dimensional and space-filling specimen
This matrix specimen is exquisite because of its geometry: four essentially vertical , slender gem aquas are perched on a horizontal aqua crystal, measuring 3.5 cm across. The crystals are glassy and gemmy and exhibit a rich blue color. The aqua terminations are totally transparent and all are nearly pristine. Elegant and beautiful!
A triangular-shaped cluster of glassy and gemmy aquas to 2.8 cm in length, perched on a matrix of white feldspar along with splendent, black crystals of schorl, to 1.5 cm across. The terminations of the aquas are transparent and nearly pristine.
Growing on and around a cluster of splendent, black schorls to 1.8 cm across, are glassy and gemmy, rich blue aquas to 4.1 cm in length. The largest aqua is also doubly terminated. All the aqua terminations are transparent and although some have very minor chips on the terminal edges , you have to look really close to see them. Unusual in the dramatic combination, and the way the aquas shoot out from teh schorl matrix.
Glassy and gemmy aqua crystals, to 3.5 cm in length, exhibit a rich blue color. White feldspar is also the host for splendent, black crystals of schorl to 1.25 cm in length. One fully terminated aqua crystal exhibiting unusual extended growth, is undamaged and yet it looks like a wedge shaped piece is missing. All the aquas have gemmy terminations and appear to be pristine. Fascinating!
Ivory colored feldspar hosts lustrous, black, schorl in crystals to 2 cm in length. These then form the matrix for a carpet of thick, glassy and gemmy, intensely colored, blue aquamarine crystals that shoot out all over the place. At the cluster atop, they reach 4 cm in length. Except for some very minor peripheral wear, the aquas that stud this specimen are in excellent condition, especially given their 3-dimensional spray and vulnerability. The piece has no damage to the major crystals and only one broken crystal of any size, at the bottom of the main cluster and really not that distracting (but the price otherwise would , in turn, be higher). The lustre and color is really tops, for this pocket and the locale as a whole. A fine example of Erongo aquamarine in LARGE size for the price range.
A 4.0 cm-long glassy and gemmy, rich blue aqua sits on a matrix of white feldspar along with crystals of splendent, black, schorl, to 0.75 cm across. The top half of the aqua is very gemmy and nearly pristine. An elegant miniature at a fair price
This is a short, stout, glassy and gemmy, rich blue aqua measuring 2.4 cm in length. Small, splendent, black schorl crystals to .5 cm are at the base of the aqua. Smaller aquas are also on the side of the main crystal; and one face has glassy and gemmy secondary, colorless beryls upon it. Very good termination. Very impressive visually, with just one (smallest) broken termination amidst the 3 intergrown crystals here.
This is a superb doubly-terminated aqua with glassy luster and gemmy tips, along with a rich blue color. In the center of the aqua is a cluster of splendent, black schorl crystals, to a few mm in length.COMPLETE all around, perfect, except only a very small contact point mid-ships on the bottom.
Just a few millimeters shorter than the previous aqua but otherwise its mirror image, this specimen is also doubly-terminated with glassy luster , and gemmy tips. And it has the same rich, blue color - they literally are almost twins. Around the center is a cluster of splendent, black schorl crystals to .4 cm across. This is a floater, complete all around, with no visible contact save a small dab of attached feldspar in the verymiddle on bottom of one face.
Situated on a small amount of white feldspar are two aquas, to 4.8 cm in length, with glassy luster and gemmy terminations along with a rich, blue color. There is minor edge wear on the terminations but it still displays very well. Also attached is the front side of a splendent, black schorl crystal measuring 1.5 cm across. The back side has been contacted.
A cute, propeller-like cluster! Splendent, black schorl crystals to 1.0 cm surround two rich blue aquas to 2 cm in length. The aquas have glassy luster and gemmy terminations and form a wide V pattern.
This is one of the most balanced pieces, aesthetically, for blue-on-black, in my whole lot. Fine, lustrous black schorl crystals, to 3 cm across, form the matrix for this specimen. They make up a roseate cluster, complete 360 degrees. The largest schorl crystal is also doubly-terminated. Rising from the center of the schorls are a half dozen, glassy and gemmy, intensely colored, blue aquas with the largest reaching 4 cm in length (from its base within the cluster, 3.5 cm freestanding). Only the very slightest wear on some crystal edges has occurred, and otherwise this specimen is pristine. For this particular pocket, where many of the pieces had damage and my source had to be very careful in picking the better specimens, this is remarkable given the exposure of that crystal. Although not the biggest, or most rich in aquas, I value this highly for its stark, simple contrast of both geometry of form and color.
This matrix specimen is chock-full of crystals arranged in an aesthetic jackstraw pattern. Emplaced on a white feldspar matrix are a score of splendent black schorl crystals, to 2.0 cm in length. Nestled in and among the schorl crystals are several rich blue aquas with glassy luster and gemmy terminations, including the largest crystal at 5.7 cm in length (as a bonus, which is also doubly terminated). Dramatic contrast of crystal forms and color, and very 3-dimensional!
Aesthetically centered and perched on white feldspar matrix are intense blue aquas highlighted by a large 3.5-cm crystal with exceptionally glassy luster and gemmy termination. Framing the aquas are several splendent, black schorl crystals to .7 cm. Very tiny chips on the terminal edges detract only minimally from this elegant specimen, which is a very dramatic, space-filling miniature. Such a robust crystal sitting nicely on matrix is difficult to get in this size range, in fact.
