One time reduction only! Was $5,400, now $5,000! If you love Distinctive Gems diamonds, you are in for something special at an unbelievable price! Distinctive Gem is known for how incredible they are at cutting diamonds for maximum performance. This Lab diamond does not disappoint! It has the much desired flower in the center. This diamond sparkles like nothing I have seen before. Regardless of the diamond being natural or a Lab diamond like this one. It is a testament to Distinctive Gem's cutting skills. It looks incredible in the photos, but the video is spectacular!!! I purchase this beautiful ring in January 2026. I have worn it 2 or 3 times. It is in excellent condition. The setting is a Stuller 14k yellow gold crown solitaire. Such a gorgeous setting that accentuates the diamond but never overwhelms... It is 2mm wide and has a depth of 1.8mm. So it is thin, but sturdy. I love how is sits in the crown, so pretty. At 3.01 ct the diamond is a great size! Measurements are : 8.87 x 8.95 x 5.90. It will come with it's IGI certificate. It is a size 7.5 and can be resized. It would make a fabulous engagement ring, or it could be a dream upgrade ring! I purchase this online during Distinctive Gems Holiday sale. The original price was $9k, marked down to $6k. I am taking another $1k off of my cost!!! This is a fantastic opportunity to get a ring from Distinctive Gem's at an amazing price!!! Right now on DG's website there is a 3.04ct for $6,950. That is for the loose stone only and doesn't include the setting. It's like saving $2k on the diamond and getting the setting for free with my price! I ship in the US only. I now will also pay the 3.5% PayPal fee- yet another savings!!! I will pay for shipping and insurance. Signature confirmation will be required. Please ask any and all questions as this is a final sale. I can be reached at: plwalter@sio.midco.net Thanks for looking! https://youtube.com/shorts/8F3WOjhdgTs?feature=share
