Help - issue with Platinum wedding ring - inset with diamonds.

Hello.I have a problem with my wedding ring (designed and made in march this year). It is inset with 14 small diamonds on the top. On the inside of the band there are small holes under each diamond. One of these holes has hugely increased in size and I don't know why and what might be causing it. I wondered if perhaps a piece of grit had got inside and is carving it out? I contacted the company who made our ring. They said they didn't know what was causing it. I'm currently living in the Middle East for work so can't take it back to get fixed in the near future. Does anybody have any experience if this or know what might be happening? The hole is getting so large I'm worried the diamond on top might drop or the hole might reach the edge of the ring. It's a fairly thin band. Thank you so much for any advice or insight you might have.
