In our opinion, the central diamond measuring approximately 10.2 x 8.3 x 5.7mm and weighing 3.66 carats is approximately I colour, SI2 clarity (small crystal under table, typical minor chipping to girdle), with strong blue fluorescence. Beautifully proportioned old mine cut with plenty of charm. Shoulder stones approximately J/K colour, VS clarity. An impressive and attractive ring in good condition, gross weight 9 grams.
