Client Experiences

Verified 5-star feedback from customers who chose Bespoke Carat for rare and custom lab-grown diamonds.

I got a 1ctw portrait cut diamond and received it a couple of days ago. The shipping time was reasonable to receive it. Customer service was very friendly and helpful and I can tell they love what they do. The diamond itself is as described and I have no issues with the parcel.

Beautiful cut, and cute color..really very happy with the purchase.. I had a ring made which didn’t have quality trapezoid side stones which detracted from the center stone.. these match perfectly!! Thank you
