Great stones and full transparency on the quality that you are getting.

Also great customer service and responsiveness! It can be very confusing to buy a diamond for the first time. Two tips: 1. The usual metrics are not enough to differentiate the quality of the diamond: In doing my research, I read that 40% of the diamonds are rated as “excellent” by GIA. At Whiteflash they are very transparent with the light performance (not just the usual metrics, but actual light performance analysis — ideal scope images, aset images, hearts and arrows) you can really get the top 5-10% quality if you want the diamond to be cut to perfection! 2: Ultimately, it is more about the cut, than about the color or clarity (and even about the carat). A slightly smaller diamond with an ideal cut will look much better that a bigger diamond with an ok cut. Whiteflash allows you to tell the difference!

The bracelet was even more beautiful in person than I expected.

I had such a great experience working with Becca at Whiteflash! I was looking for a very specific pear-shaped lab diamond, and she was incredibly helpful, patient, and personable throughout the process. She took the time to answer all of my questions and sent me multiple photos and videos of the stone in different lighting so I could really assess it before making a decision. Although that particular pear ultimately wasn’t the right one for me, I ended up purchasing a stunning lab diamond tennis bracelet with Becca’s help. She went above and beyond to make sure we chose the right size for my small wrist, and the bracelet was even more beautiful in person than I expected. Her customer service didn’t stop after the purchase, either. I was having trouble figuring out the secure clasp when it arrived, and she quickly sent me a video walking me through exactly how to use it. The entire experience felt personal and never pushy. Becca genuinely seemed invested in helping me find pieces I would love rather than simply making a sale. I’ll absolutely be returning to Whiteflash for future purchases and would highly recommend working with her!

I am located in Florida and completely satisfied with my experience in purchasing an engagement ring with Whiteflash. I mainly worked with Becca who is extremely knowledgeable and was patient with me while explaining certain differences. My fiancée loves the ring and couldn't be happier. I'd recommend using Whiteflash and you'll be in good hands with Becca!

I love my beautiful pendant!

I had a wonderful experience ordering a lab diamond pendant from Whiteflash. It can be stressful ordering a piece of jewelry without seeing it in person first, but Liza was extremely helpful and answered all of my questions. I had the necklace customized with a slightly thicker chain, lobster claw clasp, and extender. The final piece was exactly what I wanted and much better quality than I found in local stores. I absolutely recommend Whiteflash!
