oval engagement ring

I fell in love with oval shaped rings and when me and my now fiancé were discussing how one day we would like to get married, I remember looking at rings and accidentally stumbled across Lily Arkwright. At first, I thought what a beautiful range of rings they offer and then learned about Moissanite. And the more I learned about that gem stone, the more in love I fell with it. One of the most important qualities was that it’s eco-friendly yet as great as diamond and much more affordable. I remember showing the ring I found on Lily Arkwright website to my then boyfriend. And few months later I have received the biggest surprise of all, not only he proposed, but he proposed with my dream ring from Lily Arkwright. He said that after extensive research he couldn’t find a better place to purchase the ring of my dream. However it was quite big for my finger, so the next day after our engagement I have contacted the team regarding resizing. And that was the second surprise I have had, because I’ve never had better customer service in my life. Emma and Sarah were very fast to respond and extremely helpful and patient with me and all my questions. After shipping my ring back (from Prague) it took them less than 10 days to not only resize, but ship it back to me. If I could give 10 stars, I would without hesitation. Many jewelry stores have good product, but here you will also find exceptional service on top of amazingly beautiful jewelry. Very safe and amazing shopping experience with such a huge selection of engagement rings of all sizes and shapes, not just round cut you see everywhere, but oval, pear, cushion, with halo. Thank you Lily Arkwright team for making this the happiest moment of my life even though I had to send it back for a bit for resizing. Now it’s back and I can’t stop staring at it!
