I designed a custom engagement ring with Estrell and it turned out even better than I imagined. The whole process was super easy and the team really listened to what I wanted.

I ordered a memorial diamond for my dad and I can’t even explain how special it feels to wear it every day. The team at Estrell was so kind and made the process simple, which meant a lot.

I got a necklace from Estrell and wow… it’s so pretty and sparkly! You’d never know it’s lab-grown. I feel really good about this purchase.

These gold earrings I've created for my wifes birthday are absolutely stunning! They arrived in just two weeks, beautifully packaged in a sleek, elegant box.

I bought myself a bracelet just for fun and I can’t stop looking at it. Seriously looks like a natural diamond but without the crazy price tag.
