Here are 4 unheated round Vietnamese rubies with super intense and open colors. All show a mix of red/orange/pink. They have more or less silk and one has a tiny blue sapphire zoning in it! Otherwise eye clean. Lovely cut without windows. Together exactly 1ct. and they are between 3.55 and 3.85mm in diameter. The color is unfortunately not to catch accurate with my phone. They look much more red/orange red in person. Two of them I would even say super saturated padparadscha colors. Small but very fine and intense colored. They glow and catch the eye from quite a distance. In the video they look again way to much pink. On the second pic they look closest to how they look in real but still a bit to much pink there. https://youtu.be/nThUcNPOzn0 Shipping with insurance and tracking number by Swiss Post.

8.74ct. low heat sleepy lavender sapphire. Impressive sapphire with a very well saturated color and a unique sleepy look! The color and appearance of the sapphire shift very slightly from what I would describe as a purple on the pinkish side in yellow light to a purple on the bluish side in daylight. Also the sleepy look of the sapphire changes depend on the light and situation. But both, color and silk are just great! No bad or unattractive tones, beautiful saturation, never to dark or to pale, additionally the sleepiness of the silk witch depend on the light boost the color or soften the appearance. Its a gem with many beautiful faces! I was a bit surprised that GRS gave it lavender. Maybe it still falls in the color range but I guess also because of the well saturation and attractively color without any bad tones, hues ect. Beside the ultra tiny silk the sapphire has no inclusions to see by eye. If the sapphire gets high temperature heated the silk would disappear completely and it would be a loupe clean sapphire! Only on the backside in the middle of the pavilion is a small fingerprint inclusion almost parallel to a facet (to see in the (zoomed) video). Just a tiny bit under the surface. It is not to see at all from the front. The crown is super lovely balanced cut! The pavilion is of great symmetry but a little bit to deep (to preserve weight). That create a small window. A very shy recut of the pavilion would close the window, cut away the small very surface close fingerprint inclusion and would make it a perfect beauty. No face up size to loose as well as that amazing perfect shape and crown not should be touched. The video is made with the Iphone 11 on a completely cloudy late winter afternoon. The pic is a snap shot in bright mixed light with the IPhone 5. Will load up more videos in different light conditions during the next time. Unfortunately GRS wasn't able to be 100% sure about the origin. Im almost 100% sure when and were it very exactly was mined. GRS had a second possible country in the range witch they not could exclude for very sure. So no origin here on that one.

Vietnamese color-change spinel!! Bough this beauty few years ago from Brad (Thegemtrader) It is an amazing stone and the pictures from Brad don't even show the full spectrum of colors this spinel shows. There is many more hues to see. Its very sensitive how the spinel show his color depend on the light. In the early morning till late morning it is a distinctive blue inside the color, on midday there is already a mix between lavender and blue. In the afternoon there is a soft pure lavender with some hints of blue flashes to see. And like i already told it is very depend on the light how the stone plays with all this hues! I live in Lucerne just in front of the Swiss Alps and we have very changeable weather here. Especially in the first two years i watched the stone for hours during the day. In incandescent light it turns full to a lovely lavender without any blue. But in the most modern indoor lights are often blue flashes to see. In candellight its a pure purplish lavender without a blue tone. Please see also the description from Brad (easy to google!) During the last two years the stone was 99.9% inside my bank deposit box. Thats now the reason why i sell many of my gems. Most of them are from Vietnam. I hope I'm able to do some faithful pics of them during the next time. The stone never has been set in jewellery (like all my stones, I'm a collector) and is in perfect conditions. I did also a GRS-Certificate that shows that the stone is unheated and of Vietnam origin. The Certificate is also inside the purchase. The first pic is from Brad and in the last one i tried to show the blue component in early morning light but my camera darked it much to much down. I don't have professional foto-equipment, my pics are made with my old sony digicam. If you have any questions please contact me on email: alex.zacher@bluewin.ch

Unheated lavender sapphire witch has a fine soft and bit a mysterious appearance. Thats because the sapphire is equally filled with numerous fingerprints witch breaks the light and soften the appearance. More often common in spinel. The sapphire is perfectly centered and has an almost meet point cut. No nicks or cracks on the surface, the only small issue is a bigger fingerprint inclusion witch is slightly to see under the table. But overall appearance is lovely and unique in his way.
