Congratulations on your upcoming anniversary! I agree w/
@essiedub ’s comment above. The cut quality of your current diamond appears to be better than the proposed stone, which appears to be dark/dead in the center. This could be due to the angle of the photo or dirt, but it could also be the result of less-then-ideal proportions and angles that don’t work well to reflect light through the stone. Cut quality is the number one factor in how bright and sparkly a diamond appears under various lighting. Jewelry store lighting is specifically designed to make even poorly cut diamonds light bright and sparkly and should not be used to gauge diamond quality. A better barometer is to view diamonds in regular, every day lighting (dull office lighting, shade, sun, etc.). An “excellent” cut grade per the lab report does not in and of itself guarantee an well cut diamond. Before you proceed, I’d recommend researching cut quality…which should not be confused with the cut grade from the lab report (which are often regarded as being overly broad ranges), or worse yet from an appraisal or gemologist or jeweler’s report, which are just opinions and are not nearly as reliable as lab reports from independent, third party labs (with GIA and AGS being the most valuable). Settings are are simple to change and a good jeweler should offer to reset the diamond into the setting of your choice (or even sell you the diamond loose so you can have it set elsewhere). Good luck!
