Geological History

In the remote area of Macula in the Zambezia province of Mozambique in Southern Africa lies an area of mining claims mined by local artisanal miners. These miners search daily for the much sought after “Santa Maria Afrique” Aquamarine that exists below the surface in pegmatites hundreds of millions of years old.

Pegmatites are igneous rocks which form during the final stages of a magma’s crystallization. In the early stages of crystallization of the magma in this area, the ions that form high-temperature minerals were depleted from the melt. Rare ions that did not participate in the crystallization of common rock-forming minerals became concentrated in the melt and in the excluded water. These ions formed this beautiful Aquamarine. This gorgeous, sparkling gem lay below the earth’s surface for many hundreds of millions of years, its brilliance masked by the tons of rock above it, until finally it was hued from the earth and sunlight released its inner fire.

Once mined, gemologists from Lapigems Gem Company negotiated to purchase the finest crystals of which this piece was one. It was then taken to the Lapigems cutting offices and carefully cut to international standards. Because these gems are highly dichroic (meaning that they have different colors on different axes of the crystal), they have to be carefully cut to get the best color. The aquamarines from this deposit are deep blue on one axis, and light green on the other. If the stone is cut with the green axis facing up, then the blue will be far less prominent, resulting in an inferior stone. Hence the cutter had to be very careful to cut on the correct axis to maximize the color. Often this axis is the smaller axis resulting in a smaller stone than would have been achieved cutting on the greener axis and this was the case with this stone. The result was this spectacular, rare Aquamarine.
