Lab-grown diamonds are chemically, physically and optically identical to mined ones — even a jeweller needs specialist equipment to tell them apart. The only real difference? You keep thousands in your pocket.
Shop the collectionOn A Wish was born from a lifelong dream of building something my own. Jewelry making started as a comfort activity in early childhood, grew into my AP Art project in high school, and never really let go — even after college, when I spent evenings in metalworking classes while working a day job in corporate communications. In 2026, discovering lab diamonds opened up a new world of possibility, drawing me back to my design roots and giving shape to the eclectic, beautiful pieces I create today.
From first sketch to final polish, let's design a piece that's made just for you. We'd love to make your wish come true — let us know what you're looking for and we'll be in touch within 24 hours to discuss bespoke services.
Yes. Lab-grown diamonds are identical to natural diamonds, without the same price tag. All our lab diamonds (excluding some of our smallest stones, which are F color, VS1 clarity) are graded and come with a certification report, usually IGI unless otherwise noted.
We only work with solid precious metals–either sterling silver, or solid gold. We will always specify the metal used in our product descriptions.
We want you to be 100% satisfied with your purchase. We offer 10-day returns of unworn jewelry in its original packaging. Custom and bespoke orders are final sale, since each piece is made specifically for you.
We ship (ground shipping) the next business day for all in-stock orders. Bespoke orders will ship upon completion. If you need expedited shipping, please reach out for a quote and we will do our best to accommodate.
All our pieces are designed and manufactured in the United States.
