99.9% Pure Cerium Oxide
This is the "Super Cerium" sometimes referred to as "French" Cerium. This finely graded cerium oxide is highly recommended for all facet polishing where cerium oxide is suitable. It is effective on quartz, beryl, sunstone, Cristinite, and many other gemstones.
We recommend a 1200 prepolish (our preference is NuBond 1200) to smooth the surface before polishing to help obtain a high quality finish in a minimum of time.
