Supernovae (SNe) are believed to be the dominant sources of dust production at high redshift. However, the reverse shock generated by the interaction of the SN forward shock and the interstellar medium (ISM) significantly reduces the mass of newly formed dust in SN ejecta. This study quantifies the mass, composition, and grain size distribution of surviving dust after the passage of the reverse shock using the GRASHrev model. Our analysis covers a grid of SN models with progenitor masses $13\,M_\odot\leq m_\star\leq120M_\odot$, metallicity $-3\leq\text{[Fe/H]}\leq0$, and rotation velocities $v = 0$ and $300\,\mathrm{km\,s^{-1}}$. The SN explosions occur in a uniform ISM with densities $n_\text{ISM} = 0.05, 0.5$, and $5\text{ cm}^{-3}$. We find that the larger grains ($\gtrsim10\text{ nm}$) are more resistant to destruction by the reverse shock, with amorphous carbon dominating the surviving dust mass in most models. The surviving dust mass decreases with increasing ISM density. For non-rotating progenitors, the maximum mass of dust surviving the passage of the reverse shock is $\simeq 0.02\,M_\odot$ released by SN explosions of a $120\,M_\odot$ progenitor with $\text{[Fe/H]}=0$ in the ISM density $0.5\,\text{cm}^{-3}$, corresponding to $\simeq4\%$ of the initial dust mass before the passage of the reverse shock. Among rotating progenitors, a maximum surviving mass fraction is $\simeq5\%$ with a final dust mass $\simeq0.03\,M_\odot$ in $\text{[Fe/H]}=-1$ models. Although the reverse shock has a strong destructive impact, our results indicate that, on very short timescales, SNe can enrich the ISM with carbonaceous grains ranging in size from approximately $1\text{ nm}$ to $100\text{ nm}$ (up to $\simeq1\,\mathrm{μm}$ in non-rotating models). This is notable given the detection of the 2175 Å extinction bump in galaxies at $z>6$, suggesting the early presence of such dust.
