IDL SERVICES IDL offers an unparalleled level of service and many of your questions may be answered below. We are an independent testing laboratory operating in the Ramat-Gan Diamond Bourse and we evaluate diamonds and precious gemstones and jewelry for shops & businesses, trades people, fabricators, manufacturers, and private individuals. Our highly trained professional gemologists have undergone extensive training and have hands on experience in jewelry manufacturing and fabrication as well as stone setting and repairs. This unique blend of expertise provides our staff with specialized skills in ascertaining not only the quality of diamonds and gemstones sent to us for grading or insurance assessment but also affirmation of the integrity of fine quality jewelry, estate pieces, and unique hand crafted goods. Many of our international customers send us their jewelry after repair work has been completed by independent shops to re-evaluate and re-issue certification assuring them that their treasured keepsakes maintain the high value which they have paid for. Insurance companies often advise updating certificates at least every 10 years or more often as high value items may be significantly undervalued based on out of date certification. For more information about any of our services, we invite you to have a conversation with one of our expert Diamond evaluators and Jewelry Consultants by calling +44 (0) 845 108 5757, Monday through Friday from 08:00 a.m. to 20:00 p.m. UK Time, or email us at: Info@IDiamondLab.com
