Citron, also know as Lemon Chrysoprase, is a lemon to light lime colored form of Chrysoprase. Citron (Lemon Chrysoprase) varies from AA grade (without any matrix material) to B grade (with brown to gold matrix webbing). Our Citron A is Light Lime Green in color with no Matrix material & our Citron w/ Matrix is a beautiful lemon yellow with brown to golden matrix webbing - Both are from South Africa.
Chrysoprase is one of the rarest and most valuable of the chalcedonies. Its green color comes from nickel; the color can fade, and in a moist environment may also recover. Larger broken pieces are often fissured with irregular colors. Chrysoprase often occurs as nodules or in crevices in nickel deposits. Chalcedony is the cryptocrystalline variety of quartz, meaning the crystals are too small to even be seen by a microscope. by: Spencer Lapidary | |
