Comment: Tanzania has long provided the only regular (as opposed to occasionally) source of color change sapphires, most under one carat; moving between green at day and red-purple at night. The handshot below was taken in strong but natural daylight and there green dominates. The main image, on the other hand, was taken in typically mixed color settings of daily indoors live. There the gem sparkles with a cold metallic purple. Flashes of alternatively green or orange-red sparks are visible depending on the composition of its light surroundings. The extremes of pure green and red-purple must be forced from the gem with a torch (one of the exceptions when we use artificial light in our photos). With 44 points it will sit well in a slender ladies' ring up to size five and surprise you with ever different color combinations. One inclusion is visible only under the loop but not to the unaided eye. Almost round at first sight. No window and untreated gives us a 3*NOS gem. Its lab report currently snails through custom-services. Note the backside image displaying some color-zoning that is not visible from the front. Since all grading of colored gems is done from the front only, we still have a gem without color zoning. With or without CC a pleasant all-natural gemstone plus an interesting extra.
P.S. The unusual circumstances of this year, personal and in general, have so far hindered us from getting lab reports done, although I dare hope this will change by late May when I will visit Antwerp in person. The price here quoted is EXCLUDING our usual certificate. If you like to have a lab report for this garnet we need to add between $100 for a full IGI report. A $1,000 premium AIG report seems out of dimensions for a 'normal' almandine. But it too, would need a good deal extra time (currently over 12 weeks, sigh). That prices in this P.S. section differ is no lazy mistake but reflects the different pricing policies of the gem labs we use. Some calculate via weight, e.g. a 7 carat garnet is more expensive to test than a one carat, others labs go via pieces, when a small sapphire costs as much as a 10 carat gem.
