Overall Condition: Very Good
Condition Notes: At the heart of the design is a Colombian emerald measuring 16.72 × 14.81 × 9.55 mm, distinguished by its saturated green hue. Under magnification, inclusions consistent with F2 clarity enhancement confirm GIA’s assessment, with moderate resin present in surface cavities. Just beneath the table, a pyrite inclusion slightly breaks the surface from the cutting process. Within the chain, one marquise-cut diamond bears a chip to its pavilion side, while the remaining diamonds appear cleaner in clarity than the stated SI average. The clasp is marked for both the stone weight and the designer, Michael Christoff.
