Diamond Grading Reports

Kalista Jewels only works with the most respected diamond grading labs. Because these labs have the highest standards for diamond grading, you'll find diamonds certified by these labs tend to carry a premium. Our diamonds have received the highest grades of quality, so they are guaranteed to be the highest quality diamonds available. The GIA, founded in 1931, established the standards for grading diamonds and provides gemologist training and supplies diamond knowledge to the industry today. The founder of the GIA went on to form the AGSL in 1934, to create a society of jewelers focused on consumer education and promoting ethical business practices within the diamond industry. in 1996 the AGS opened a diamond grading lab — the AGSL — a non-profit agency with the mission of providing stringent, standardized grading reports. Their mission is to establish a trusted set of criteria to evaluate diamond cut. This in turn, promotes the production of more diamonds cut for maximum sparkle, rather than cut to maximize carat weight.
