When it comes to melee diamonds, not all stones are created equal. You’ve probably heard about lab-grown options—but what really sets them apart from natural melee diamonds? And more importantly, how do you know which is right for your designs and your customers?
In this blog, we’ll break down the key differences — clearly and simply — so you can finally understand what makes each type unique and why Grunberger Diamonds exclusively supplies natural melee diamonds.
What Are Lab-Grown Melee Diamonds?
Lab-grown diamonds are produced using high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD) methods that mimic the earth’s natural processes. Though they share a similar chemical structure with natural diamonds, lab-grown melee diamonds are not formed by nature. They’re made in a controlled lab environment, often in a matter of weeks.
Recently, the Gemological Institute of America (GIA) announced it will no longer provide full grading reports for lab-grown diamonds. Instead, it will only offer generalized assessments. This shift further underscores the ongoing differences between natural and lab-grown stones and why transparency and traceability are increasingly important for consumers and jewelers alike.
