Changing size of center stone in setting


I want to change the 8X7mm 3 ct oblong radiant cut stone to a 9X9MM 4 ct princess cut. I have a custom three stone with .75 trilions on either side in like a basket prong setting. Is this a cheap fix or major work? I have the stone 🙂 My husband won't even know lol


Hi Anne,

It could be a cheap fix depending on the design. Metal has memory; a jeweler could try to bend the prongs and force the new diamond to fit. However, this could dramatically impact aesthetics and stability. The size of the trillions may also affect the look of the ring. For long term security and piece of mind, you may want to consider redoing the whole ring if budget permits. Check with your trusted local jeweler.
