Type of Stone: Diamond
Shape: Dodecahedron
Carats: 1.225
Measurements: 6.1x6.21x4.8mm
Color: F-G
Description: Lovely compacted dodecahedral raw diamond - by compacted we mean that it's more rounded as dodecahedrons tend to be oblong. This stone has very nice lines and angles, it's smooth and clear and very gemmy. It holds a white and golden light, and because of the many faces, it refracts them in many direction. There are some tiny wisps of matter trapped in the stone that make this an even more interesting rough diamond. It's very fancy and will set beautifully in any of our rings.
Source: DTC (the Diamond Trading Company), we are quite certain it is from South Africa but new provenance claim rules from the DTC require that we state it is from Namibia, South Africa, Botswana or Canada.
Certifications: This stone was traded between borders completely in keeping with the Kimberley Process and is therefore conflict-free and does not finance violence by rebel groups seeking to undermine legitimate governments anywhere on earth.
Description : This gorgeous step cut square sapphire is insane. It is completely natural, no heat treatments, and really, it's just beautiful. It's anice size and color, definitely consider this for an amazing sapphire engagement ring.
