Alpinite
  Alpinite is a Signity exclusive innovation. It mimics the ever-popular green colours of emerald and peridot. Because it's singly refractive, this man-made stone boasts constant colour throughout. It also has a high refractive index, yielding an eye-catching sparkle and shine and jewellery-grade hardness for superior wearability.
