The "gm" on a ring typically stands for "grams," indicating the weight of the metal used in the ring. This measurement is important for assessing the ring's material quality and value. Additionally, it can also signify the density of the material, which can affect the ring's durability and overall appearance.
375 means the ring is 9 carat gold & GM 16 may mean the ring weighs 16grams
