Jewels also created the Mask Norns, which she dedicated to her sister Jennifer and her unborn baby, both killed in a car accident caused by a drunk driver on 31 May 1999. This breed was followed by the Mask Ettins and Mask Grendels. Shortly after, Jewels began work on a new Norn breed for C3/DS that resembled blue-colored Primrose Norns, but they were never completed.
Unfortunately, after battling cancer for several years, Jewels suffered a stroke on 29 January 2001 and died a day afterwards. She was mourned by many in the community.
Most of Jewels' work was available at her website, Scientist of the Mask - her creations are now available on other community websites like Creatures Unlimited (direct link) and Juli's Norn Pad (archived).
