FINE EMERALD AND DIAMOND RING

Centring on a rectangular modified step-cut emerald weighing 13.78 carats, flanked by shield-shaped and tapered baguette diamonds, mounted in platinum. Ring size: 5¾

Colour and Clarity: According to both AGL and SSEF reports, the emerald is natural, of Colombian origin, with no indications of clarity enhancement. Both have specical appendix, stating that this emerald comes from the most famed Muzo mining area, representing a particularly fine example of Colombian emerald. Please refer to the report and appendix for details. In our opinion, the emerald is of strong green colour, eye clean. Upon 10x loupe, there are only a few minor natural inclusions close to a corner, overall quite clean. Diamonds on the shank are about E to F colours, VS clarity. Condition: Platinum ring mount, in very good condition.
