Comment: This year's winning pair of all-natural blue topaz: Precision-cut-to-match from the same Colorado crystal. Distinct blue, "fancy blue" in diamond-speak and equally rare (yes, blue diamonds are rare, too). In Peter's special cushion brilliant they give all shiny glimmer you may wish for. One is free of inclusions, the other shows, under the lens only, a vertical bluish veil, the edges of which I have caught on photo below (visible only under the lens and then only with good eyes). Double AGL certified untreated. See big side-image for a view on the cutting quality and the photo of the rough with the color zone showing (thanks to Peter T.). Top class in every dimension, physically, spiritually and, of course, financially.
