Tennis necklaces, side by side

All five are diamond tennis-style necklaces in rose gold, and each listing says it is UK Assay Office hallmarked. The main differences are the carat figures and the diamond options: one lists a carat range of 2.00ct to 21.00ct and another 3ct to 28ct, and several offer natural or lab-grown stones. Choose by the look you want and the size range you need.

Side by side.

Our own readings for each, then what the shops’ listings say. A gap means the listing doesn’t say, not that the product lacks it.
