Comment: Flawless cinnamon coloured zircon cut as diamond brilliant. Near five carats. Precision cutting. No window, perfect dimensions. Earthy rich hue with a mild glow of orange brown and a little yellow. Zircon is durable and has the finest optical features (close to diamond for which is often used as substitute). Unheated gemstone from Ceylon. No inclusions even under the lens. Not to be confused with Zirconia, which is a synthetic diamond imitation. This is an all-natural product as it was found in the rivers of Sri Lanka and has not been altered except for faceting and polishing. Still great value in untreated gemstones, but prices are rising under the pressure that comes from under-supply in all natural gems. Can make a pair with ROZ452 (use search box).
