No.
On the Mohs Scale of hardness, the hardness comparisons are exactly opposite. Talc is rated as 1 -- soft, and diamond is rated as 10 -- hard, in fact, the hardest rating.
The Mohs scale. # Talc # Gypsum # Calcite # Fluorite # Apatite # Feldspar # Quartz # Topaz # Corundum # Diamond The Mohs scale, however, is an purely ordinal scale. For example, corundum (9) is twice as hard as topaz (8), but diamond (10) is almost four times as hard as corundum. Check the related link for more info.
No. Talc is the softest mineral. It can't scratch anything that is harder that itself. Talc is number 1 on the Mohs scale, a scale of hardness, but diamond is number 10, which means that diamond is very much the harder of the two. You can't even scratch a diamond with a fingernail, hardness of about 2.5, so talc with even less hardness doesn't stand a chance against the mighty diamond! See Related Links below this box for more information about the hardness of talc, diamonds and other materials.
Hardness is the resistance of a gem to scratching and abrasion. It is one of the key qualities of a gemstone. Diamond is the hardest gemstone. The second hardest gemstone is corundum (ruby and sapphire).
The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. Ithardnesses

Talc - softest Gypsum Calcite Fluorite Apatite Orthoclase feldspar Quartz Topaz Corundum Diamond -hardest
Well the mohs hardness scale, goes upwarda by 1 everytime and diamond (10) being the hardest is Talc Gypsum Calcite Flurite Appatite Fieldspat Quartz Topaz Corundum Diamond
The basic Moh's hardness scale consists of: 1. Talc (softest) 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond (hardest)
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
Using the geological Moh's scale of hardness of minerals: 1 - Talc 2 - Gypsum 3 - Calcite 4 - Fluorite 5 - Apatite 6 - Feldspar 7 - Quartz 8 - Topaz 9 - Corundum 10 - Diamond
Talc is the softest mineral.. here is the mohs scale of hardness 1. talc 2. gypsum 3.calcite 4.fluorite 5.apatite 6.orthoclase 7. quartz 8. topaz 9. corundum 10.diamond
The correct order of minerals from softest to hardest, based on the Mohs scale of mineral hardness, is talc (1), gypsum (2), calcite (3), fluorite (4), apatite (5), orthoclase feldspar (6), quartz (7), topaz (8), corundum (9), and diamond (10). Each mineral is rated according to its ability to scratch others, with talc being the softest and diamond the hardest.
There are ten degrees of mineral hardness, the softest (1) being talc and the hardest (10) being diamond. 1: talc 2: gypsum 3: calcite 4: fluorite 5: apatite 6: orthoclase feldspar 7: quartz 8: topaz 9: corundum 10: diamond
Orthoclase comes in as 6 on Mohs scale of mineral hardness:- Talc, Gypsum, Calcite, Fluorite, Apatite, Orthoclase, Quartz, Topaz, Corundum, Diamond;
The scale goes from 1 to 10 Talc (talcum powder) is the softest Diamond is the hardest examples of each point on the scale are: 1. Talc (Mg3Si4O10(OH)2) 2. Gypsum (CaSO4·2H2O) 3. Calcite (CaCO3) 4. Fluorite (CaF2) 5. Apatite (Ca5(PO4)3(OH-,Cl-,F-)) 6. Orthoclase Feldspar (KAlSi3O8) 7. Quartz (SiO2) 8. Topaz (Al2SiO4(OH-,F-)2) 9. Corundum (Al2O3) 10. Diamond (C)
The hardest mineral is diamond, and the softest mineral is talc.
The hardness of minerals is measured using Mohs scale. Minerals are ranked due to their relative hardness from 1 to 10; 1 being the softest, and 10 being the hardest.10 Diamond 9 Corundum 8 Topaz 7 Quartz (porcelain - 7) 6 Orthoclase (steel file - 6.5) 5 Apatite (knife blade or nail - 5, window glass - 5.5) 4 Fluorite 3 Calcite 2 Gypsum (fingernail - 2) 1 Talc.
