This beautiful vintage Art Deco era mounting has been recently paired with a specialty Old European Cut Lab diamond chosen for exceptional beauty. We seek out stones with smaller tables, large culets, and steeper angles to enhance the coveted historic visual effect called kozibe —like those found in antique heritage diamonds where the center facet located on the bottom of the diamond is reflected up and around the edges like a kaleidoscope. This combination makes a stunning presentation for the vintage loving bride. A beautiful floral design in the gallery is accentuated with tiny hand applied milgrain detail while carved acanthus leaves decorate the shoulders. A delight to view from every angle, the setting is light, airy and feminine - as an extra special detail even the double claw prongs feature delicate engraving. This is simply a beautiful ring, waiting to be admired by all and loved for a lifetime by one. $4200 Layaway Eligible www.Heritagejewelry.com In person viewings are available by appointment at our Edmond, Ok office.

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. I was able to stack this ring with a ring cuff and wedding band (cuff and band not included). This is an absolutely beautiful engagement ring, but my husband purchased a new ring for me for our anniversary. 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 Price is firm, but it includes free insured shipping within the US. All sales final.
