Each Whitney Boin ring is custom made to order. Production takes 3 weeks from date of purchase. Each engagement ring begins once the diamond is received or purchased by Whitney Boin Studio. All rings are hand fabricated from precious metal sheet, wire and tubing to exact specifications. All stones are hand picked and measured. WBS uses G color and VS clarity diamonds in all bands unless otherwise requested. All rings are available in Platinum, 18k gold, 18k white gold or palladium. Special orders for different metal or diamonds are accomodated upon request.
