1894 CRYSTAL GROUP CITRINE 65 x 60 x 43 cm 106 kg Provenance: Swiss private collection Citrine is a variety of quartz, whose yellow colour is due to the presence of minute amounts of iron oxides in the mineral. It is rarely found in its natural state, especially in such a massive size. Historically, it was believed that citrine would bring wealth and prosperity, lending to its nickname as the „money stone“. The example presented here is one of the largest Citrine groups ever offered at an auction. In size, weight and quality, this example really leaves one speechless. CHF 135 000 / 160 000 (€ 131 070 / 155 340)
