  • What’s the difference between a Lab-Grown Diamond (aka synthetic, man-made, or cultured diamond) and a Diamond Simulant?
    Diamond simulants are NOT diamonds. The most common simulants are cubic zirconia and moissanite - they are man-made and DO NOT have the same chemical and physical characteristics as natural or synthetic diamonds. Simulants scratch much easier, can discolor over time, and don’t carry the same thermal conductivity properties as natural diamonds. Hence, they also tend to be far less expensive than natural diamonds.
  • Do lab-grown diamonds come in different shapes, cuts, and sizes?
    Yes. Just like mined diamonds, lab-grown diamonds are cut and polished from a rough-cut diamond stone so they are available in virtually all shapes, cuts and sizes.
  • If lab-grown diamonds and natural diamonds have all the same physical and chemical characteristics, how do I know if I’m buying a lab-grown diamond or a natural diamond?
    That is a great question! Lab-grown diamond manufacturers are required to laser engrave the girdle of the diamond to identify it as a lab-created diamond. The laser engraving can be seen using a traditional 10x jewelry loupe. Without the engraving, it is virtually impossible to distinguish cultured from natural using magnification or traditional diamond testing equipment. We are confident that ethical cultured diamond manufacturers are properly identifying their products. While not currently a prevalent problem, the opportunity certainly exists for unethical manufacturers to try to pass off their lab-created diamonds as natural diamonds. The good news is that there are now more sophisticated (and expensive) testing equipment available that can identify if a diamond is natural or lab-created. At K.Hollis Jewelers, we only carry lab-grown diamonds produced by ethical manufacturers that can verify the diamond source, provides laser inscription and certification for their products. K.Hollis Jewelers also has a high-end diamond tester that can distinguish lab-grown diamonds from natural diamonds so you will ALWAYS know exactly what you are buying.
  • What’s different between natural and lab-grown (cultured) diamonds?
    ORIGIN: Lab-grown diamonds come from above the ground; mined diamonds come from below the ground. CREATION TIME: Thanks to science, lab-grown diamonds take approximately one month to grow, while mined diamonds take millions of years. COST: Current technology makes lab-grown diamonds cost-efficient and easier on your budget. A Lab-grown Diamond from reputable manufacturer current costs anywhere from 20 to 40 percent less than a mined stone. This allows you to buy a similar lab-grown diamond for less OR buy a larger, higher quality lab-grown diamond for the money you were planning to spend on a natural diamond. ENVIRONMENTAL IMPACT: Created in labs rather than dangerous mines, lab-grown diamonds are safe, conflict-free, and have fewer adverse effects on the earth.
  • What are the similarities between natural diamonds and lab-created?
    OPTICAL: Their sparkle is indistinguishable. PHYSICAL: Their shape is the same. CHEMICAL: Both are comprised of 100 percent carbon. CREATION: Lab-grown diamonds are created under the same conditions as mined diamonds where carbon is exposed to intense heat and pressure. The only difference is that lab-grown diamonds are created in a chamber in about a month, speeding up the million-year underground process of mined diamond creation.
