Vivid Blue Sapphire - 0.73ct Cushion Cut - Natural Ceylon Sapphire

Eye clean means that when you look at the stone with the naked eye, no inclusions interrupt the colour or catch your attention. For a 0.73 carat unheated Ceylon blue sapphire, reaching eye clean without any clarity treatment is a genuine mark of quality, since untreated stones this clean are harder to source than heated ones. I still recommend a loupe check before purchase if you want to see the internal character up close.

Vivid Blue is my own descriptive shorthand, not a formal grade issued by any lab. I use it here because the hue reads as a strong, saturated blue with even tone across the cushion shape, rather than leaning toward the greyer or lighter tones some trade names imply. It's a judgment call based on handling the stone myself, and the certificate itself simply confirms colour as part of its natural, unheated description.

At 5.04 x 5 x 3.39mm, this cushion cut sapphire has enough surface area to read as a proper patch of colour rather than a small accent, and the excellent cut grade keeps the facets active in light. I'd set it in a simple bezel or four-prong ring mount to let the colour lead, though its compact depth also suits a pendant if you want the stone to sit close to the skin. Either way, the cut is doing the work of making 0.73 carats look considered rather than modest.

I can confirm Sri Lanka as the country of origin, which the certificate itself states, but I don't claim a specific mine or gem field for this stone since that level of detail isn't something I can verify for every parcel that comes through. What I can stand behind is that it moved through traceable, ethical channels before reaching me, and that Ceylon sapphires from this region have a long, well-documented history of producing exactly this kind of natural, unheated blue.
