Faceted Oval.  10.26mm x 8.3mm.  2.55 Carats.  This is a gorgeous Aquamarine but does have a couple of tiny inclusions that I had to REALLY inspect to see them..  The cut and color is just stunning!  Color will vary based on lighting.  Sizes are approximate.  Please accept my apologies for any fingerprints on the gemstones in the photos.
