Helixx tension set rings

[tmogilnicki]

Two years ago I purchased a "helixx tension set" engagement ring (princes cut diamond set in white gold). Recently my wife noticed that the stone is pulled from its setting (~500µm) which is visible and somewhat frightening. I took several photomicrographs of the ring, which suggest that the ring is trying to shape itself back to the original form. Is it possible? Has anyone heard of this problem before? What is the likelihood of this being a design flaw?

PS If anyone is interested I have several photomicrographs available. Please let me know if you would like to take a look at them.
