It truly has been a Brilliant Diamond Buying Experience.
October 26, 2026
My mind was blown when I opened that beautiful little black box to find the shiniest diamond ever. It brought tears to my eyes. Not only was the diamond beyond my expectations, so was the treatment I have been given by your company. Your thoughtfulness and attention to my transaction has been a testament to the quality of your product and the professionalism of your company. In a world where customer service is at best lacking, you rank far and above your competition. Thank you and your staff so much for taking care of me every step of the way. It truly has been a "Brilliant Diamond Buying Experience".

A huge shout-out to Becca at Whiteflash, she was an absolute joy to work with!
October 15, 2026
Buying a stone for an engagement ring can easily feel overwhelming, but Becca made the entire process completely seamless and stress-free. She provided expert guidance and gave us complete confidence and assurance that we were choosing the exact right stone for us. From start to finish, Becca was remarkably responsive to all of my calls and emails, incredibly helpful, and brought such a warm, positive energy to the experience. We could not be happier with our decision. If you are looking for an exceptional, stress-free diamond buying experience, ask for Becca!

I had a great experience purchasing a diamond pendant from Whiteflash.
October 09, 2026
Becca was extremely helpful throughout the process. She took the time to understand what I was looking for, provided thoughtful recommendations, and helped me compare several diamonds without any pressure to spend more. I ultimately chose a 0.74ct A CUT ABOVE diamond, and I’m very happy with the result. The diamond is beautiful, and its brilliance exceeded my expectations. I really appreciate Becca’s professionalism and guidance. Highly recommended!

Proposing—San Jose Style!

With its sunny skies, palm trees, and never-ending list of things to do, San Jose is the perfect place for a romantic proposal. Try one of these unique local ideas:
  • Nothing says proposal like an engagement ring and a million roses, so pack a romantic picnic of cheese, fruit and champagne and pop the question at the San Jose Municipal Rose Garden.
  • After an elegant evening at the San Jose Repertory Theater and a perfect dinner at Arcadia, ask her to marry you and she will be sure to say yes.
  • Loyal San Jose sports fans would love nothing more than a proposal on the ice at the world-famous Shark Tank. Catching a San Jose Sharks game would just be icing on the cake.
  • Cater to her interests. An art lover would enjoy a proposal at the San Jose Museum of Art, while a cinephile would appreciate a romantic proposal at the Cinequest film festival, and a computer geek will flip over an after-hours tour of the Tech Museum.
  • Propose at the top of a roller coaster at California’s Great America. Just save the engagement ring until you’re safely back on solid ground.
  • Nothing says classic California comfort food like a burger and friend from In-N-Out Burger. Hide the ring (in a clear box!) at the bottom of that delectable bag of golden fries.
  • More of an adventurous couple? Take advantage of all the outdoorsy options San Jose has to offer, and spend a day biking the Guadelupe River Trail or hiking through Alum Rock Park.
Since Whiteflash is primary an e-tailer, they can provide reasonable prices on the highest quality diamonds that San Jose jewelers just can’t match. Whiteflash’s easy-to-use website and friendly agents will help you build your dream engagement ring and then ship it to you overnight—for free!

For engagement rings, wedding bands, and any other kind of diamond jewelry, trust Whiteflash to provide top-notch diamonds and the best customer service.
