Damaged Quad-Center Princess Cut Diamond Ring

This item is a contemporary-style diamond ring crafted in what appears to be white gold or platinum, featuring a central square head designed to hold four princess-cut diamonds in an invisible or tension-style setting. The shank is further adorned with channel-set square stones, likely smaller princess-cut diamonds, extending down the shoulders. A significant and critical condition issue is immediately apparent: one of the four primary center stones is missing from the upper-right quadrant of the center setting, leaving an empty void and exposing the underlying metal structure. The remaining three center stones exhibit a bright white color with visible internal reflections characteristic of diamonds. The setting shows signs of wear, including minor abrasions and potential deformation of the prongs that originally secured the central cluster. This style of 'invisible' setting for multiple stones to mimic a larger solitaire was highly popular in mass-market jewelry from the late 1990s through the 2010s. The overall craftsmanship suggests a commercial-grade production, though a final appraisal would require testing the metal purity and verifying the gemstone authenticity/carat weight.
