Why are Tourmalines often cut as rectangles?

If you’ve ever visited MADLY and checked out our extensive Tourmaline collection, you may have noticed that Tourmalines are often shaped as rectangles, be it ‘Emerald’ cut, rectangular step-cuts or elongated cushions.

The best lapidarists understand that each stone has an ideal shape that helps maximise its full potential. And for Tourmalines, that shape happens to be rectangles — here’s why!

Tourmalines grow in long, elongated clusters with flat sides. Thus, rectangles just make sense, since it utilises the natural formation of the crystals to its advantage. This helps to make the most of the rough weight for a bigger, bolder stone!

When it comes to coloured gems, it’s all about that vibrant hue! Or in the case of bi- and tri-coloured Tourmalines, HUES! Watermelon Tourmalines like the ring above are cut in long rectangles to showcase their unique colour zoning of pink/red to green. Aligning the table facet parallel to the crystal’s length, helps capture and display this stunning colour contrast more effectively.
