A 2.52 carat round old European cut lab-created strontium titanate with 0.76 carats of round white zircon in 18K yellow gold over sterling silver ring - the diamond simulant ring in the old European cut, a historical round cut with a smaller table, higher crown, and more geometric facet arrangement than modern brilliant cuts. The old European cut creates a different, more intimate light performance than modern rounds - a softer, more vintage-feeling optical character. In warm gold. Not sizeable.
