Gemstone Carat and Size Guide: Choosing a Stone for Your Setting
Carat weight is not the same as visible size. Two stones of similar weight can look different because their species, shape, proportions and cut differ. A good selection compares both the stated carat weight and the listed dimensions.
Carat and dimensions work together
Carat describes weight; millimetre measurements describe the stone’s physical length, width and depth. Use both fields when comparing products. A product page should be the source for the exact item, while the lab-report guide shows how those details may appear in supporting documentation.
Shape, colour and visible presence
Cut shape, crown height, depth and colour can change how large or bright a stone appears. Online photographs are helpful but are not a substitute for dimensions. The photography and colour guide explains screen and lighting variation.
Plan for the setting
A stone intended for a ring, pendant or bracelet should be compared with the setting type, mounting dimensions and everyday wear. Consult a qualified jeweller before modifying a stone or setting. Read the jewellery setting guide and the care guide for practical handling.
