Substantial heart and beautiful chain. It was more expensive than I’m used to paying, but upon seeing the quality I’m happy I made the purchase. The 18kt plating seems well done throughout, and the pieces that are Sterling-based are marked accordingly. The heart has a lovely Missoma hallmark on its lower edge. All came with extraordinary packaging, a cleaning cloth and small booklet highlighting additional Missoma products. I’m exceedingly pleased with the necklace, and impressed with the blazingly fast shipping. TWO DAYS from shipping from England to delivery in Connecticut, USA! Amazing.
