This 1.5 CWT engagement ring is certified through DGLA. It is a G in color and a VS2 in quality. The wedding band is also 18 k gold and has a CWT of.3. I have the certification card and appraisal documents for the set. I will certainly want to meet you at any precious jewelry establishment or bank in town so you could view the ring in individual. Please email me for the appraisal paperwork if interested.
