The invention discloses a smoke yellow crystal bead blank and a preparation method thereof. The smoke yellow crystal bead blank is prepared from the following components in parts by weight: 90-165 parts of quartz sands, 11-19 parts of zinc oxide, 28-53 parts of sodium carbonate, 15-30 parts of potassium carbonate, 5-17 parts of boric acid, 3-5 parts of calcium carbonate,0.8-3.2 parts of aluminum hydroxide, 1-2 parts of table salt, 2-5 parts of antimonous oxide, 0.1-2 parts of potassium nitrate, 0.01-0.15 part of sodium selenite, 0.001-0.003 part of ferrous sulfide, 0.1-0.8 part of samarium oxide and 0.9-2.2 parts of nickel oxide. When the smoke yellow crystal bead blank is prepared, a lot of cerous compounds are not used, colors of selenium and compounds of selenium are fixed in secondary finishing, and the bead blank is adjusted to smoke yellow by virtue of compounds of samarium and nickel. Lead-containing raw materials are not used, and the bead blank has the advantages of good glossiness, bright color, orderliness, no chromatic aberration and patterns, high yield, no lead and pollution, and good production benefit.
