Open clusters serve as laboratories to study and evaluate stellar evolution and Galactic chemical evolution models. Chemical peculiarities, such as lithium-rich giants, are rarely observed in these stellar systems. This work focuses on eight red giants (#005, #028, #034, #053, #087, #121, #126, and #190) previously reported as members of the Galactic cluster IC 2714. We conducted a detailed investigation using high-resolution spectroscopy, supplemented with data from the Gaia DR3 catalog. Besides deriving the cluster's fundamental parameters, we provide the most thorough chemical characterization of IC 2714 to date, reporting the abundance of 23 species, including light elements (Li, C, N, O), odd-Z elements (Na, Al), α-elements (Si, Ca, Ti, Mg), iron-peak elements (Sc, Cr, Ni), s-process-dominated elements (Y, Zr, Ba, La, Ce, Nd) and r-process elements (Sm, Eu). We also present the carbon isotopic ratios ¹²C/¹³C for the first time for seven stars. One particular star (#087) exhibits a high lithium abundance (${\mathrm{log}}\,\varepsilon $(Li)_NLTE = +1.54 dex) and a slightly higher projected rotational velocity ($v\,\sin \,i$ = 6.7 km s^–1). Our results suggest that the analyzed stars are in the core-helium-burning phase of evolution, where the most lithium-rich giants are found. Combining astrometric probabilities and chemical abundances, we conclude that two giants (#028 and #034) might not be cluster members.
