Loose Demantoid Garnet Gemstones
Showing the single result
Demantoid garnet is a very rare variety of Garnet that has a very intense sparkle. The dispersion number of this gemstone is higher than Diamond. Dispersion is the degree to which white light is broken into its spectral colours, the higher this number, the more sparkle the gemstone has. The original and best source of this stone is Russia, but recent finds in Namibia have redefined the affordability of this gem. Look for clean stones that have a nice saturated green colour. The more yellow the stone is, the cheaper it will be.
