Very professional, easy experience. My partner and I visited the showroom for an engagement ring consultation and were pleasantly surprised at how easy the process was. Fai, our consultant was nothing but patient, friendly and speak perfect English. They understand everything there is to know about diamonds and ring making, and give you advice on what's best for you and your ring, not their bottom line.
We went away feeling very happy with our choices and the experience as a whole. Thank you so much Luminari!


Thank you once more for your dedication to making my girl’s diamond ring truly memorable. I highly appreciate K.Fai’s straightforward and informative approach before making a decision. The diamond and ring setting exceeded my expectations and fit perfectly within the budget I had set.

LOVE LOVE their jewelry! Especially these pair of earrings for my wife! They are extremely detailed oriented. I love the craftsmanship. I am a forever customer!
”

I recommend Luminari for anyone looking for diamonds. I had no knowledge about diamonds at all and wanted to buy a ring for my girlfriend on a special occasion, so I searched on the internet until I came across and talked with the Luminari team. I felt very confident in both the quality and price. Thank you Khun Fai again because my girlfriend and I really like it.
”

I recently purchased an engagement ring from here and was thoroughly impressed by their premium service and professionalism. Their prices are incredibly reasonable for the high quality and stunning designs they offer. K.Fai made the entire process seamless and enjoyable, making it a memorable experience for such a special purchase.
”

I'm totally new to the world of lab-grown diamonds, but i'm beyond thrilled with my recent purchase from Luminari. From start to finish, Khun Fai has taken the time to understand exactly what I was looking for, answered all of my questions, ensuring that I felt confident in my purchase. Big thanks to Khun Fai for making my first purchase such a positive one!
