Customer Reviews
Consistently great experience
This isn't my first purchase from Brilliant Carbon, and once again, they delivered. I bought a pair of diamond stud earrings this time, and the quality is just as excellent as the tennis bracelet I got last year. Shipping was quick, maybe 4 days to reach Phoenix, and the packaging was secure. It's good to know I can always count on them for reliable service and beautiful jewelry. That's why I keep coming back.
Beautiful engagement ring!
I got a stunning lab-grown diamond engagement ring here, and it's absolutely gorgeous! The sparkle is incredible, and I love that it's ethically produced. The whole process was so easy, and the ring arrived faster than I expected. I will definitely shop here again for future gifts. Seriously, you should check them out!
Good value for my money
I was looking for a good deal on a solitaire pendant and found Brilliant Carbon during their anniversary sale. I got a solid 10% off which was a nice saving. The free shipping was also a plus, saving me another few bucks. The necklace is pretty, and I feel like I got a good quality item without overspending. It felt worth the purchase.
Quick delivery, good quality.
Ordered a pair of hoop earrings. They arrived quickly. Quality seems good. Happy with the purchase.
Nice ring, shipping could improve
I ordered a rose gold women's wedding band. The ring itself is lovely and exactly as pictured on the website. I appreciate that they offer IGI certified diamonds, which gives me peace of mind about the quality. My only minor complaint is that shipping took a little longer than I anticipated, about 7 business days to reach Chicago. Not a huge deal, but something to note if you're in a rush. Overall, a good experience and a beautiful product.
