Please note there is no center stone in this setting. The price is for the setting only. Allwood 3 is an adorable and authentic Retro era (dated 1942) platinum engagement mounting. It can accommodate a Round stone ranging in diameter from 5.5mm-6mm or with a Round diamond weighing approximately 0.60ct-0.80ct. Allwood 3 is flanked on either side by six Single Cut diamonds lining the shoulders and totaling approximately 0.12ct in weight. The inside shank is inscribed with a personal engraving that reads "L.G.W to R.M.T 5.28.42". The low profile makes it incredibly easy to wear every day. It is currently a size 5 and can be sized to fit most ring sizes. Please contact our concierge with sizing questions or if you'd like to see if your family stone will fit.
