KNOW YOUR STONE

Clarity
Minor inclusions invisible to the naked eye. Only detectable under magnification by trained gemologists.

Natural imperfections occur in most diamonds as internal inclusions or surface blemishes. Graded from FL (Flawless) to I1 (Included), with FL being the rarest.

Color
Virtually colorless. Only gemologists can detect the slightest difference from D grade.

Diamond color measures the absence of tint. Graded from D (colorless) to J (faint warmth), with D being the most prized for its pure, icy brilliance.

Cut
Beautiful sparkle with outstanding light performance. Nearly indistinguishable from Excellent to the naked eye.

Cut determines how light interacts with your diamond. Graded from Good to Excellent, it directly impacts brilliance, fire, and sparkle, the most important factor in a diamond's beauty.

Carat
Dimension approx. 12×6 mm

Imagery and dimensions are for reference only; your chosen stone will be accompanied by its official grading certificate.

Carat measures a diamond's weight and influences its apparent size. Cutting and polishing removes up to two-thirds of the rough stone, making large, high-quality diamonds inherently rare.

Beautiful ring

My ring is truly beautiful.. it was done in a timely manner and I was impressed that they kept me updated every step. It came beautifully packaged as well. The craftsmanship is excellent. Thank you so much.

When Art Meets Technology

Their combination of art, programming, and passion makes them unique. It’s like each ring is born from creativity and technology coming together in harmony.

Where Innovation Meets Emotion

I loved that they use technology not to replace humans but to enhance creativity. The whole process felt innovative and heartfelt at the same time.

Everyone we spoke with was very…

Everyone we spoke with was very helpful. I was worried that shipping would take longer than they said, but it arrived early. And it’s gorgeous. Most frequent comment, STUNNING!

I didn’t know much about jewelry

I didn’t know much about jewelry, but their experts made me feel like I did. They walked me through every setting, diamond, and metal type. When the final piece came, I couldn’t believe how stunning it was.

Dad approved upgrade

Recently, I found out my old man still checks brilliance under a loupe. After seeing the lab emerald cut he nodded and muttered not bad son. Trust me, that’s a medal.

my perfect upgrade find

IF YOU ASK ME, I'VE BEEN USING THEIR SERVICE FOR RING UPGRADES, AND GUESS WHAT, IT'S MY FAVE NOW. I WAS COMPLETY IMPRESSED!

Good ring, good quality. She loves it

Kept me informed throughout the process and delivered a beautiful ring

Smoothest shopping experience!

Let me tell you, I had zero stress picking out a ring. The whole process was so smooth, and they even helped me pick the perfect one. She loved it, so I win. :)

Amazing ring! Ring box too big!

Absolutely loved the ring! I have zero complaints with the ring it was perfect. The box it comes in is not my favorite. It’s big and ugly in my opinion. If you are going to bid the ring in your pocket for a proposal you’ll probably want to buy a new box for it

Jaxon Torgerson
L'Amour Brilliance
Proposal saved at the last minutes!

If I'm honest, I was completely lost when picking a ring. But they made it so easy! The moment I popped the question, her reaction said it all. The ring looked absolutely flawless, and now she won't stop showing it off. TY for making my proposal perfect!

Sean Simpson
L'Amour Brilliance
I kept sneaking peeks before proposing

I’ll admit, I was so obsessed with how the ring looked that I kept opening the box to stare at it before the big day 😂. Couldn’t help myself. The cut, the sparkle, the feel—it was all so spot on. When she finally saw it, she had that “OMG” face. Mission accomplished.

Bradley Sweeney
L'Amour Brilliance
A little help goes a long way

I was clueless about rings, but their advice? Spot on. They helped me pick something that suits her style perfectly. When she saw it, her face lit up like I had just gifted her the moon. Safe to say, I'm in her good books forever, :)

Buying a ring online feels like buying it in person

Buying a ring online feels like buying it in person! L'Amour takes great care of their customers, fast delivery. The ring is sparkling, no doubt!

It is not just a piece of jewelry, but also a symbol of love

L'Amour has breathed soul into every detail of the ring. It is not just a piece of jewelry, but also a symbol of love.
