This ring is a Ken & Dana Design crafted piece. Take a look at their website to see their work. The ring was sent to eBay Authentication and has been successfully authenticated. I will include all the paperwork I originally received with the ring as well as the eBay authentication cards. All details are listed under the item specifics. The platinum setting is modern and minimal, but extremely well made and solid. It makes the cushion cut stone the center of attention and the claw prongs elevate the piece. SPECS: Brand: Ken & Dana Designs Main Stone: IGI Cert. Lab Grown Diamond (Cushion cut) Main Stone: 2.02ct, 6.9mmx7.2mm, G/VS2 Band: Platinum Size 5.5 All sales final and price is firm.
