Frequently Asked Questions
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds with the same chemical, physical, and optical properties as natural diamonds. The difference is their origin: lab-grown diamonds are created in a controlled environment rather than formed naturally underground.
Do lab-grown diamonds come in fancy colours?
Yes. Lab-grown diamonds are available in colours such as yellow, pink, blue and other hues, depending on availability. Browse our fancy coloured lab-grown diamonds online to compare shapes, carat weights, colour intensities and prices.
How do lab-grown coloured diamonds get their colour?
Colour can develop during the diamond’s growth or through treatment after growth. Check the individual diamond’s grading report for its colour description and available treatment information.
How long will it take my diamond to arrive?
Lab-grown diamonds purchased will ship in 6-14 business days. We ship with FedEx insured priority next-day delivery. Shipping times may vary due to customs or other unforeseen events.
We will keep you updated regarding any disruptions.
Do you sell engagement rings to fit the diamond I select?

This is THE place to get the ring. Greg is an absolute fantastic person to work with and his designs are flawless. He is patient, flexible, can work with any budget, and is incredibly welcoming. He makes the process stress free and super clear. My now fiance loves her custom ring and we’ll most likely come back for the wedding bands! Highly recommend!
Had a fantastic experience with Greg at Jacob Mercari! He was incredibly helpful throughout the process, from designing the ring to selecting the perfect stone. His expertise and suggestions made all the difference. Highly recommend!
I purchased an engagement ring online from their website. It was very easy. They contacted me right away and the communication was excellent. The ring shipped in a timely manner as they said 3 weeks and it came in 3 weeks. The ring came and it was AMAZING!! my fiancé was ecstatic. I highly recommend Jacob Mercari. Wish I could give more than 5 stars.
