I Bought Diamonds from These Stores
These are full reviews based on actual purchases. I go over what I ordered, how long it took to arrive and how the diamond looked under magnification.
Why Trust My Reviews?
I don’t just list specs. I’ve bought from these stores, checked diamonds under magnification and reviewed everything from packaging to polish. Every review includes photos, videos and real pros and cons.
Do your diamond reviews include affiliate links?
Some of my reviews include affiliate links, which means I may earn a small commission if you make a purchase. It doesn’t cost you anything and never affects my opinion.
Are your reviews based on real purchases?
Yes, several of the reviews are based on actual diamond purchases and unboxings. I include photos, magnified inspections and notes on shipping times and packaging.
How do you choose which diamond stores to review?
I focus on stores that are popular, widely searched or offer something unique. I only review stores I’ve spent time analyzing and in many cases actually purchased from.
