Definition
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Pumice and Eclogite
Here you can know more about Pumice and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Eclogite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Pumice is Vesicular and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Pumice vs Eclogite. The hardness of Pumice is 6 and that of Eclogite is 3.5-4. The types of Pumice are Scoria whereas types of Eclogite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice and Eclogite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Eclogite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pumice is impact resistant, pressure resistant whereas Eclogite is heat resistant.
