Comment: Queenly in size and color, or kingly if you wish. Richly colored, free of inclusions under the lens, no window, no treatments. Noble zircon with good dispersion, warm hue, obviously not the aggressive light yellow that used to be compared to diamonds but a golden earthy golden-yellow, leaning towards ripe peaches and honey, rather than oranges and lemons. In the trade-off between strong brilliancy and rich color this six-carat may mark the medium balance, perhaps the best of both worlds, but that is a question of personal taste: for some brilliancy is the main terrific-driver in zircon (1.89), for others it is the wealth of unique colors (5.67). In any combination, zircon is still amongst the most under-valued gems around, though we watch parcel prices climbing and single clean pieces, especially in sizes that the independent precision-cutter can afford are getting rarer. For precision lapidaries zircon is the best material to show off their best work, durable, good to cut with high optical features. Zircon used to be an also-catch, brought home as pity surplus when no sapphires or tourmalines or others could be found. We even saw miners throwing small zircons back in the river when I was young, but times are changing. Consumers needed only little common knowledge to see through the diamond-scam in the last decades and there waits zircon with near comparable qualities at a tiny fraction of its prices. Flawless local hand-cut, no window, no treatments, no inclusions. With 12x8mm face-up it will need a significant ring-size or a pendant design. Increasing prices reflect increasing future replacement cost; those who sell based on old buying prices instead of future replacement cost will soon be off-line.
