Read our ring-stacking storyTotal carat weight, often written as ctw or ct. tw., is the combined weight of the diamonds in a piece. It is different from the weight of a single center diamond. Compare the number of stones, their dimensions and the setting as well.
Understand the 4CsKeep pieces separated in soft compartments and remove them before swimming, cleaning or activities that could cause a hard knock. Follow the care instructions for the particular metal and setting. Have a loose stone or damaged prong inspected before wearing the piece again.
