4 to 5 carat gemstones are a confident size for cocktail rings and pendants, big enough to show colour clearly without feeling heavy. You can compare sapphire, tourmaline, spinel, topaz and more at a similar weight.
How to choose a 4 to 5 carat stone
- Compare face-up size: denser gems like sapphire look smaller than lighter ones like tourmaline at the same weight.
- Look closer at clarity: inclusions are easier to see as stones get bigger.
- Check depth: a stone cut too deep carries weight you will not see from the top.
- Plan the setting: this size suits a halo, a solitaire or a bold pendant.
