If you are not sure of your ring size, please follow the ring-sizing guide below.
Measuring Your Finger
Your ring should fit your finger comfortably, snug enough so that it will not fall off, but loose enough to slide over your knuckle.
If ordering from outside of the US or Canada, determine your ring size according to your country’s standard. Use the International Ring Size Chart to convert to the corresponding US ring size to place your order.

This is a chart that will be extremely helpful for you to determine the ring size that you need. You can either make use of a tape or a small piece of string to measure the area that will be occupied by the ring. When it becomes a complete circle, make a mark on such string. This will be helpful for you to compare with the chart that is mentioned below.

Real customer feedback
⭐⭐⭐⭐⭐
I received my ring today, it looks fantastic!! I wanted it delivered before Christmas and since it's getting close, MWring was willing to rush the order for me and advised me to go for Fedex shipping. I'm glad I took their advice and received my ring early! MW rings look high quality, more real and more authentic than any other Moissantie diamond rings I've tried. They're worth the money!!
⭐⭐⭐⭐⭐
The ring is beautiful, it's not like others, the shank of the ring is substantial, solid enough to hold the larger 3ct. stone, which is what I sized up to. I wear it with my original eternity band and it shines right along with it. I love this and can now wear a wedding set when we go camping, vacation or anywhere I don't feel comfortable wearing my original engagement ring. Thank you!
⭐⭐⭐⭐⭐
Thank You! My rings are crafted beautifully perfect, look stunning. Arrived in time for Christmas with lovely boxes to store and present the rings in. Kept informed of order, tracked delivery service. Will recommend and order from MW again. Caring service from start to finish, checked my order and advised on my order, before making and shipping my trio of bands.
⭐⭐⭐⭐⭐
Great service I ordered 2 rings 10 days apart The bougainvillea in white gold platingwith moissanite and a matching wedding band ,both arrived together beautifully boxed .They feel sturdy ,look fabulous and I have received loads of compliments. I bought them for holidays instead of bringing my real ones. I will order again but in yellow gold my preferred choice I look forward to seeing how it turns out
⭐⭐⭐⭐⭐
I received the ring I ordered within 2 weeks and the ring is stunning. It more than exceeds my expectations. E-mail updates were provided in relation to expected delivery dates. It is difficult to see how anyone could/would buy an equivalent real diamond as this ring is so realistic. I ordered a 3 carat ring and my only concern is that it is quite a large stone and so might be hard to carry off as its so lovely. Will definitely buy again in the future :)
⭐⭐⭐⭐⭐
I ordered the MW477 Perilla Ring/Moissanite/2CT and it is stunning. The quality is excellent and it's crystal clear and sparkles better than my real diamond. The only problem I had was understanding how long it took for processing and delivery. Delivery took 13 days and the whole process was about 6 weeks. Be patient because you do receive a beautiful piece of jewelry to wear. I plan to order other pieces in the near future. Thank you MWRing!!
⭐⭐⭐⭐⭐
I've ordered from them before. It took exactly 4 weeks for my rings to arrive this time. Amazing quality rings. Love love love my new rings! Comes in beautiful Tiffany blue boxes. I'm very happy with my purchases and experience. Definitely recommend if you're looking for diamond alternative that's affordable with high quality. You literally cannot tell because they're made so well.
⭐⭐⭐⭐⭐
