8 to 9 carat gemstones are collector-level sizes, large enough to anchor a pendant, a cocktail ring or a bespoke design. In this range, species that grow in larger crystals, such as tourmaline, aquamarine and topaz, are easier to find.
How to choose an 8 to 9 carat gemstone
- Look hard at colour: at this size, every shift in tone is on show.
- Ask for a lab report on precious stones: a big ruby, sapphire or emerald deserves independent identification.
- Think about practicality: large stones in rings can knock easily, so pendants are often easier to wear.
- Plan the mount: heavy stones need strong prongs and a well-made gallery.
