anniversary upgrade. 3 carat radiant cut F set with trillions- this stone changes in every light condition, from rainbows to white light. I am loving it, it does something new and unexpected all throughout the day- in twilight it is magical- a carnival of rainbows. Finding the stone in the diamond district, getting it set in a warren of booths was an amazing adventure! Here it is with my beloved hydrangeas before the fall frost!
