8.68 ct Lab-Grown Moissanite Diamond Ring - Stunning Round Cut | Celebrity Style | Valued at £3,500 Hey! With regret, needing to sell this engagement ring ASAP. It has recently had an insurance valuation of £3,500 (photo attached). Ideally looking for £2,500 but will also consider sensible offer as keen for a quick sale. Happy to answer any questions - over the phone if needed. I also have a video of the ring. It really is beautiful and would make a lovely engagement ring or even an investment addition to a collection.
