Casterton is beautiful and authentic early Edwardian (Circa 1910) platinum and 14k rose gold ring that most likely started life out as an earring. The ring centers a 1.96ct Cushion Cut sapphire accompanied by a Guild Laboratories certificate stating the sapphire is Heated with Thai origin. The ocean blue stone is further surrounded by a gorgeous halo of twelve Old Mine Cut diamonds, each individually prong set, totaling approximately 0.80ct in combined total weight. This timeless beauty encompasses a lasting combination of sparkling diamonds centered by a deeply saturated sapphire. The ring is finished with a newly added 14k rose gold shank and is currently a size 6.5 and can be sized to fit.
