Discover the Dazzle of Lab-Grown Diamonds at National Estate Jewelry Buyers

Diamonds are often a symbol of love, coming from the Greek word adamas - meaning unbreakable. Perhaps it’s now time for you to buy that special diamond for that special person - confidently. Many people coming to National Estate Jewelry Buyers often ask whether it is better to purchase a lab-grown diamond or a mined diamond. Providing unbiased information to our clients helps them understand the benefits of each.


For some, purchasing a mined diamond is important - it’s the mystery and glamour of nature’s miracle, as well as maintaining the tradition of our parents, grandparents and so on. However, lab-grown diamonds are becoming more and more trendy - popular and sought after, especially as their quality and size reaches new levels.


Lab-Grown Diamonds:

  1. Real Diamonds: Sometimes referred to as man-made diamonds or lab-created diamonds… lab-grown diamonds are real diamonds, just like mined diamonds. They are not duplicate diamonds - such as Cubic Zirconia.

  2. Origin: Lab-grown diamonds are grown in one of two ways - Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) in a lab, whereas mined diamonds, are naturally formed 1 - 3 billion years ago beneath the surface of the earth. Thanks to highly sophisticated, state-of-the-art technology, the natural growing process is able to be duplicated.

  3. Same Gradings: GIA labs certify lab-grown and mined diamonds the same way - using the 4C’s (color, cut, carat and clarity).

  4. Multiple Benefits: Lab-grown diamonds are generally less expensive, often kinder to the environment and offer peace of mind knowing the origin, in comparison to mined diamonds.
