Marble is more sensible.
I suppose that a marble statue is more sensible (excepting wood statues).
The Appalachian Mountains in northern Georgia are most likely to be affected by weathering due to their elevation, exposed rock surfaces, and frequent precipitation, which can lead to erosion.
The property least likely to be affected by weathering of a mineral is its crystal structure. While weathering can alter other characteristics such as color, hardness, and luster due to physical or chemical changes, the fundamental arrangement of atoms in the crystal lattice remains largely intact unless the mineral is completely broken down. This stability in crystal structure allows the mineral to retain its identity despite surface alterations.
Chemical weathering is more likely in a city due to higher concentrations of pollutants like sulfur dioxide and nitrogen oxides produced by urban activities. These pollutants can mix with rainwater to form acid rain, which accelerates chemical weathering processes on buildings and structures in the city. In contrast, rural areas have lower pollution levels, reducing the occurrence of chemical weathering.
The rock you are referring to is likely granite. Granite is a commonly occurring igneous rock that contains minerals such as quartz and feldspar. Due to its durability and resistance to weathering, granite is often used in construction for countertops, monuments, and building facades.

Chemical weathering is most likely to occur in areas with high temperatures, abundant moisture, and exposure to oxygen. This is because these environmental conditions accelerate chemical reactions that break down minerals in rocks. Areas with tropical climates or high levels of rainfall are prime locations for chemical weathering to take place.
Quartz is the tough mineral most likely to survive extensive chemical weathering and form sand grains on beaches or dunes. Its hardness and resistance to chemical weathering make it a common component of sand in these environments.
An increase in temperature and precipitation would likely cause the greatest increase in chemical weathering of local bedrock. Higher temperatures can accelerate chemical reactions, while increased precipitation can provide more water to facilitate the weathering process.
Chemical weathering is the breakdown of rocks through chemical reactions. Examples include dissolution, oxidation, and hydrolysis. It is likely to occur in humid climates with warm temperatures and abundant rainfall, as these conditions promote faster chemical reactions.
Most likely it would have been subjected to far more weathering; in paticular, a type ofphysical weathering called frost wedging. Cleopatra's needle is carved of granite and when exposed to constant freezing and thawing in severe climates such as most of Siberia experiences granite exhibits this type of weathering. Granite typically has small cracks and fissures or joints which can fill with water. Even though Siberia is relatively dry some water would be available to do this (over long periods of time especially). Water expands when it freezes which causes a wedging effect inside the crack and causes plates of rock to crack off. Over time this would most likely happen to Cleopatra's Needle in Siberia

The rate of weathering of a granite monument placed outside for 200 years in a cool, dry climate would likely be slow. Granite is a durable and resistant rock type, particularly in such conditions where there are minimal moisture and temperature fluctuations. However, over an extended period, there may still be some weathering due to physical processes like freeze-thaw cycles or chemical weathering from pollutants in the air. Overall, the monument would likely show some signs of weathering, but at a slower rate compared to more harsh environmental conditions.
