Excellent experience from start to finish! I purchased a pair of diamond earrings for my wife, and the entire process was fantastic. Sahil was incredibly thorough, knowledgeable, and always quick to respond to my questions. He went above and beyond to make sure I was comfortable and confident with my purchase. Excellent customer service, beautiful earrings, and an overall great experience. Highly recommend Carat Theory!

The studs are exquisite, sparkly and beautifully mounted. The packaging made for a most impressive presentation. It was a perfect 15th anniversary gift for my wife.

Verified purchase

I recently purchased a piece of jewelry from this store, and I am beyond impressed with the entire experience. The jewelry itself is stunning, crafted with incredible attention to detail and even more breathtaking in person than it appeared online.
What truly sets them apart, however, is the unmatched customer service and personal touch. The unboxing experience felt like opening a luxury gift, complete with gorgeous, thoughtful packaging that made the moment feel truly special. On top of that, their follow-up after the purchase was warm, professional, and genuinely caring. It is rare to find a brand that goes so far above and beyond to ensure a customer is completely delighted.
I couldn't be happier with my purchase and will definitely be a returning customer. Highly, highly recommend!

Anniversary gift to myself

The heart and pear together make such a unique shape, I haven't seen anything like it. It's substantial but still elegant. I shortened the chain to 17 inches and it sits perfectly. People stop me to ask about it.

For the big nights

These are a serious statement. Wore them to a gala and felt incredible all night. The Asscher stones are gorgeous and there's sparkle everywhere. Not everyday earrings for me, but completely worth it for special events.

One for each of my kids

Bought this to represent my three kids. The stones are different sizes which makes it even more perfect. It sits nicely at the base of my neck.

Sunny little necklace

The radiant with the round stones is such a pretty combination. Yellow gold is warm and bright. I wear it every day with basically everything.

Dainty but noticeable

The row of little ovals is so pretty, and the slider means I can adjust the length whenever I want. I wear it looser in the day and snug at night. The rose gold is gorgeous.

Long and elegant

These are longer than I thought they'd be but that's what makes them. Two pears that swing when you move. Perfect with an updo.

The classic, done right

I've always wanted a real tennis bracelet and this one is perfect. Ordered the 6.5" and it has just a little room to move on my wrist. Every stone is bright, no dull ones anywhere. Feels very secure.

Like wearing a little sculpture

The mix of shapes is so cool, the Asscher and kite stones make it look almost architectural. I'm an interior designer and these are completely my taste lol. Heavier than basic hoops but comfortable for a full day.

Gorgeous pendant

The pendant itself is stunning. The chain is on the finer side, which suits the look, but I'm a bit paranoid about snagging it so I'm careful with it. Otherwise perfect.

Ovals really do look bigger

Chose oval over round because I read they look bigger for the carat weight, and it's true. Long and elegant on the ear. Very happy with them.

The Ascension Climber The Ascension ClimberExplore this piece

Was nervous about a climber, needn't have been

First ear climber I've ever owned. I was worried it wouldn't sit right because my lobes are on the small side but it follows the curve of my ear really nicely. The marquise stones mixed in with the rounds are my favourite part. Wore it all day at a wedding and forgot it was there.
