Kosmima Fine Jewelry — Attraction in Brookline

Cathi and Pano are absolute gems (pun intended). I came into Kosmima with a family ring that was given to me wondering whether i should re set it or start fresh. Pano gave me an honest assessment of the diamond and a comparison to the specs that I was interested in if I went with new. He walked me through every step of the process and helped me decide on an amazing ring that blew my partner away.

Flash forward a year and a half and many covid strains and unfortunately the engagement ended (it's all good, we are both happier this way and remained friends!). While this is already a stressful enough situation as is, I had no idea how to properly re sell a diamond without getting taken for a ride. I did a ton of research and brough the ring to a few places as well as looked online. Pano and Cathi worked with me in such akindly manner and were able to give me the most fair price I had been offered on a buy back.

Even hurriedly brought out the piece and announced how when he kept it on the scale it was so small that the scale wouldn't even register it. The whole situation was unpleasant and very rude. I would not recommend the place to any...

Cathi and Pano are wonderful people and wonderful jewelers.

I bought four items of jewelry here: a diamond necklace to propose to my then-girlfriend, her custom-made sapphire engagement ring, and finally our custom gold wedding bands with engravings. Cathi and Pano worked hard to make our visions for the rings a reality, and my wife and I are thrilled with how each piece looks and fits. We were a little late getting the rings designed, but Cathi and Pano still had everything ready with time to spare before our wedding date.

What really stands out about Cathi and Pano is their friendly demeanor and their transparency about cost and about the feasibility of different design details. We always knew exactly what we were getting, and Pano was very thoughtful about the little details of fit and style that wouldn't have...
