Stone: Color Change Garnet Weight: 5.00 cts Clarity: SI Dimensions: 11.20 x 8.07x 5.20mm Design: Modified Emerald Origin: Umba Valley, Tanzania Treatment: None Cut by: John B. Notes: This is a rare find in this size and from this area. This rough was discovered in the Umba River Valley of Tanzania by an individual miner. This stone is dark like most of the blue color change garnets but the size makes up for it. There is a small inclusion in the bottom of the pavilion which is not seen from the table view. There are a couple of small bubbles in the stone and some very light silt. This stone was faceted from the rough. I have been keeping this stone in my personal collection due to the availability of this type of material and along with the size of the stone. However I decided to list it once again to see if we can find it a good home. This is a rare chance to own a large blue color change garnet.

Clarity: VS Dimensions: 5.39x 4.90x 3.42 mm Design: Broken Moon brilliant (modified round brilliant) Origin: Longido, Tanzania Treatment: None (presence of silt seen with magnification) Cut by: John B. Notes: It is very rare that I list a stone with the color of vivid, but this is that rare time. This one of a kind untreated ruby from Tanzania was faceted from rough supplied by one of my best sources direct from Tanzania. Neither the photos nor the video reflect the true beauty of this stone. This vivid stop light red is outstanding with incredible brilliance. The stone was faceted with a rare design I named broken moon for it's unusual shape. This will make one heck of a center stone. The stone appears perfectly clean by the eye and with maginifaction you can barely see the silt and one tiny inclusion.

Tanzanite comes from only one source in the world in Tanzania. One source gemstones in fine qualities are true rarities. Most Tanzanite have a more Purplish color to it but in the trade the more Blue the Tanzanite is, the more desirable and valuable it is. The shine and brilliance this gemstone shows is absolutely stunning. In addition to its size and color, this Tanzanite is a great competitor or substitute to the Blue Sapphire.
