Laboratory-grown diamonds are developed in laboratories and factories over short periods of time. A rapid increase in this technology over the past decade has added to the availability of laboratory-grown diamonds in the jewelry marketplace. Now, more than ever, full disclosure and confidence in knowing what you are buying is critical.
