After a long time I faceted a new very big Rhodolite. This time it was an alluvial marble-shaped piece from Tanga, Tanzania with a purplish red colour.

This one was a hard fight. The rough was a big piece with 2.5 gram and only one half had a better clarity. The result still has many internals, but hey this is a Demantoid with over one carat! WIsh I would have more roughs even with this inclusions. The "Lighthouse of Porporela" with extra steep angles gave an extra portion of colour and dispersive flashes.
