5.53 ct. Moroccan Cobaltian Calcite
Such large and fine
this interesting variety are extremely uncommon. As is often the case with
such rarities, this is an old collection stone - stored quietly away as this
type of material has been absent from the market for decades. The level of
transparency is uncommonly fine (particularly coupled with the size) and the
custom cutting is superb. The special color is actually caused by Cobalt -
an unusual example of this element resulting in a pink hue. There are many
small, often quite cloudy, examples of Cobaltocalcite on the market - these are
typically cut from Spanish material while this beauty is from a classic Moroccan specimen.
With just the right lighting you can actually see the rounded botyriodal growth
pattern that is diasgnostic of this material.
There is always some pain associated with collection stones as they are nearly
impossible to replace once gone.
