  • Round Cut Dark Blue 6.8mm/1.28ct Thailand Sapphire Loose Gemstone

    1 item left

    This unusual round-faceted cut dark blue 1.28ct Sapphire from Thailand is available for a custom-built ring by Nodeform Jewelry.

    Select a ring setting that fits the shape and size of this selected one-of-a-kind gemstone. Add both to your cart and we'll create your ring!

    The well-cut gemstone has a stunning deep blue color. In LED lighting it shows some teal green areas but outside in natural light, it's mostly a dark blue color. This gemstone will look best in more open settings like prongs and half bezel settings that let more light in. For a full bezel setting, it may be too dark (unless you prefer dark stones).

    About Heat Treatments: Some colored gemstones are routinely heated for color and clarity improvement. This is a permanent treatment and typically only involves heat and not chemicals. The treatment mimics what the earth does naturally to gemstones as they reach the surface.
