My fiancee and I actually got engaged on Valentines Day this year and he gave me a beautiful platinum ring with a princess cut center stones and baguettes and round diamonds on the sides. Unfortunately, because of stupidity on my part, I lost it in the ocean at Seaside Florida after watching a fellow sunbather lose a TWENTY CARAT TENNIS BRACELET (you''d think I would have thought to not wear my jewelry on the beach after seeing that). Anyways- We have now bought a setting to replace it that is an absolutely stunning tacori style ring with two baguettes on the sides. Now I am struggling with whether to buy an oval or emerald cut diamond for the center stone. I have found two beautiful diamonds, both are very good cuts, E, VS2. The Oval cut is 1.12 carats and the emerald cut is 1.02 carats. I wanted to know if the market value for the two cuts varies widely (if that makes sense) and if any one has suggestions on which I should choose from an investment standpoint (I guess I am thinking long term. Also, If I were to upgrade in the future would I have to upgrade to the same shape or could choose a different one. Thanks for your responses!
