Stone Ring – A ring that has one or more gemstones or decorative stones set into it (rather than being a plain metal band). These stones can be precious (like diamonds, rubies, emeralds) or semi-precious (like amethyst, garnet, sapphire, or cubic zirconia). 

6gm – Indicates the approximate weight of the ring’s metal (around 6 grams). Jewellery weight is used by jewellers to estimate metal cost (especially for gold or silver) and overall heft of the piece. Rings with stones typically list metal weight separately from stone carat weight.

21058 – This is very likely a model number or SKU (stock keeping code) used by the manufacturer or store to identify this specific design. It helps the jeweller track inventory, style, and variants.
