Rare Carat Lab-Grown Diamond Review

Rare Carat makes my shortlist for a lab-grown engagement ring around $1,200 before tax. I found a 1.46-carat round diamond for $615 and paired it with a $600 white-gold solitaire. The cart came to $1,215. That’s the figure I would use to compare jewelers, even though Rare Carat put a much bigger “savings” number next to it.

What I liked most was being able to take the report number and look for the very same diamond elsewhere. What frustrated me was finding two promising stones through search only to discover both were gone. Starting from Rare Carat’s own diamond search worked better.

Our bottom-line verdict

Rare Carat is a good place to price a simple solitaire when you know roughly what size you want. The $1,215 sample cart is a realistic starting point for the specific ring I built. I would check the same report elsewhere and make sure the stone is still selectable before settling on it.

Is Rare Carat legitimate?

Yes. Rare Carat is an online jeweler that works with diamond suppliers and says it handles orders and customer service itself. The diamond I put in the cart had an identifiable IGI report number. Before buying, match the report to the listing and confirm the return deadline for your order. Rare Carat FAQ

Rare Carat diamond prices

I looked for lab-grown rounds between 1.45 and 1.60 carats. The four selectable E-color, VS2-clarity diamonds I opened were $615 to $790. Here’s what that looked like in our November 7, 2026 US shopping check.

The 1.57-carat stone cost $105 more than the 1.46-carat stone. Open both reports and compare their diameters and videos before paying the extra. The change in weight is easy to see in a table. The difference you’ll see on a hand depends on how the stones are cut. The 1.46-carat listing I used

What the engagement ring cost in my cart

I picked the Linda Comfort-Fit solitaire in 14K white gold. Its slim 1.5 mm band made it a good starting point for pricing a simple ring. The cart showed $615 for the diamond, $600 for the setting and free shipping. The $1,215 estimate was before I selected a size or entered an address for tax.

The cart also showed $635 in savings against its own $1,850 comparison value. Use the $1,215 figure when comparing orders. If you find another ring you like for a similar total, compare the width, height and fit of the two settings along with the diamonds. The setting was nearly half the cost of this ring, so it deserves as much attention as the stone. Rare Carat’s setting catalog

Would I ask for a price match?

Yes, if I could find the exact stone at a lower price and both listings were available. I searched for IGI LG811691990, the report number on the $615 diamond. An indexed Ritani listing showed the same number, but I couldn’t confirm that the stone was still available there. I stopped at that point.

Rare Carat asks for the same report number, a public US-dollar price and proof of availability before purchase. A different E/VS2 round can still be a better buy, but it’s a separate comparison. If you do find the same report, save both links and ask Rare Carat for the confirmed price before you pay. The indexed Ritani listing · Rare Carat’s price-match terms

What it’s like to choose a diamond

The report number field is the feature I would come back for. It lets you search for a diamond you already have in mind. If you’re still browsing, pick a size range and keep two or three candidates open. Two 1.50-carat G/VS1 rounds I found through search were marked unavailable when I opened the product pages. I found the four selectable stones above through Rare Carat’s own filters. Rare Carat lab-grown diamond search

I would use “Rare Carat Ideal” as a filter and make the decision with the report and actual-stone video. For a round, start with the diameter and watch how evenly the diamond lights up as it turns. Rare Carat says it checks the stone against the report before shipping and handles fulfillment and service itself, including when the listing names a supplier.

How to narrow down the choices

Set the budget for the whole ring first. On a $1,200 budget, spending $800 on the center leaves $400 for the mount. The solitaire I chose cost $600. Knowing that up front gave me a better idea of where to set the diamond filter.

E and VS2 gave me a convenient group to compare. If you want more room in the budget, open a few near-colorless candidates and watch their videos against similar backgrounds. Check where inclusions sit, particularly under the center. I would pay for a difference I can see in the stone before paying for a grade I struggle to see. Our lab-grown diamond grading guide

The 1.5 mm band is a delicate look. If you wear rings hard or want a wider band, compare a sturdier setting before buying the diamond. Ask how high the stone will sit and whether your wedding band can fit alongside it. Our engagement-ring buying guide

Returns and resizing

Rare Carat’s standard US window is 30 days from shipment for eligible orders. Keep the original paperwork and packaging and check the deadline on your order, particularly around the holidays. Rare Carat advertises a free first resize within a year, but its return policy excludes items sent in for resizing. I would decide whether I wanted to keep the ring before sending it in for a fit adjustment. Return instructions · US services and warranty

Would I buy from Rare Carat?

I would keep the $1,215 solitaire on the shortlist if I liked the slim band and could see enough of the exact diamond to choose it. Check Ritani for the same report or a comparable round, then get a second complete-ring price. If I were less sure about the setting, I would put some of that shopping time into trying rings at a showroom. Our Ritani review · Our Brilliant Earth review

How we reviewed Rare Carat

I looked at four things: whether I could find an available stone, how much the listing told me about it, how clearly the builder explained the finished-ring price, and what the terms would mean once the ring arrived. I used four selectable search results, two unavailable indexed listings and one sample cart. The cart and policy checks support the buying advice here. Delivery, workmanship and aftercare still need an order test before we rate those parts of the purchase. Our editorial review process
