I am absolutely obsessed! I have the Lindsey ring with an oval 3.06-carat stone in a size 5. The pictures and videos I've seen on Instagram and the web page don’t do it justice—it’s stunning, classy,... See more

The support team was very responsive and the responses felt very personalized and like the person on the other end really cared. I had a few questions about my order and the whole thing felt very genuine and one-on-one. They cared about making the right ring and I even got responses to my inquiries immediately and late in to the evening. The ring arrived ahead of schedule and was perfect. I would recommend Keizer to everybody.

She loved the ring! I had a last second ring size change and y’all accommodated. Thank you so much!
The customer service with Keyzar is amazing. Anyone nervous about purchasing online, you will be not be let down with Keyzar.
I thought it looked good in the pictures and when it came in it was even better. Didn’t take long to get it made and shipped either.
I had a really positive experience purchasing a lab-grown diamond engagement ring from Keyzar.
One of the first things that stood out to me was how reasonable the pricing was compared to many other lab-grown diamond brands I had researched. They also offer a wide variety of settings and styles, which made it easy to find something that matched exactly what I was looking for.
I ordered a platinum setting, and the production time was faster than I expected — it took less than three weeks to be made, and it was shipped and delivered before Christmas, which was a huge plus for me.
What impressed me the most, though, was the craftsmanship. Before ordering from Keyzar, I had visited several brick-and-mortar stores and seen finished rings from other lab-grown diamond brands, and honestly, many of those settings didn’t feel very refined or well-finished. In contrast, the ring I received from Keyzar was beautifully made — the details were clean, the setting felt solid, and overall it looked much more polished than I had anticipated.
Overall, I’m extremely happy with this purchase. The combination of fair pricing, fast turnaround, and high-quality craftsmanship made this a very satisfying experience, and I would absolutely recommend Keyzar to anyone considering a lab-grown diamond ring.
Easy web ordering, communication was prompt throughout the process from ordering to delivery.
Multiple and unique choices
Easy to explore and pick
Good quality and great customer service
The ring is absolutely beautiful anybody thinking about what if it doesn’t look good in person please put those thoughts to rest it is a gorgeous ring
Purchased a band for as a Christmas gift on Nov. 24th 2025. Received a band on Dec. 4th. Except it wasn’t what I ordered. They shipped platinum and I ordered 14k White Gold. They were quick to respond that they shipped the more expensive platinum. Thanks, but not what I ordered and needed 14k White. Shipped it back, and they said “they’d do their best.. I emailed on Dec 18th and even suggested that we can switch to a different style if that would help. Nope.. we are working to get it to you. Well, here I am on Dec 24th with no ring. Beyond disappointed.

I did not have a chance to deal with anyone direct, but the site, selection, text communication on updates and the shipping via FedEx was all as expected and delivered early by over 9 days! That’s impressive.
Customer service was so patient with me as I changed my mind three different times and they were so quick to respond.
My ring is the most beautiful thing I have ever seen!
