The undulating form of this carved onyx druzy evokes a scene of scintillating stars in a clear, dark sky, with the gemstone’s grey detailing the galaxies in our universe, gradually revealed by the natural waves of the gem. (You could say that the wearer will have the universe close to their heart). Rudolf Heltzel has magnificently framed this interesting onyx druzy with a textured white gold frame surrounded by another but polished yellow gold frame, all following the contours of the gemstone.
