Do Lab-Created Diamonds Hold Their Value?

Lab-created diamonds, also known as lab-grown or synthetic diamonds, are gemstones cultivated in a laboratory setting. They share the exact same chemical, physical, and optical properties as natural diamonds, differing only in origin: grown in a controlled environment rather than extracted from the earth. This article explores their value retention over time.

Fundamentals of Diamond Valuation

A diamond’s value, whether natural or lab-created, is universally assessed based on the “4 Cs”: Carat Weight, Cut, Color, and Clarity. Carat weight refers to the diamond’s size, with larger stones generally commanding higher prices. The cut evaluates the quality of a diamond’s facets and proportions, influencing how effectively it reflects light and exhibits brilliance. Color assesses the absence of color in a diamond, with colorless stones being the most valuable. Clarity measures the presence of internal inclusions or external blemishes, with fewer imperfections leading to a higher grade and increased value.

The Value of Lab-Created Diamonds

The value trajectory of lab-created diamonds differs significantly from that of natural diamonds due to their distinct production and supply dynamics. Advancements in manufacturing technology, such as High-Pressure, High-Temperature (HPHT) and Chemical Vapor Deposition (CVD) methods, have led to increasingly efficient and lower-cost production. For instance, the cost to produce a single lab-grown diamond per carat has seen a substantial decrease over the past decade.

This continuous improvement in technology, coupled with the ability to produce an essentially unlimited supply, directly impacts their long-term market value. Unlike the finite supply of natural diamonds, lab-created diamonds can be manufactured on demand, diminishing their rarity. Consequently, their value behavior is more akin to a manufactured consumer good rather than a rare commodity, generally experiencing a depreciation trend over time.

Lab-created diamonds typically cost 30% to 85% less than natural diamonds of comparable quality. This lower initial price reflects their market reality, where value tends to decline as production becomes more efficient and supply increases.

Selling Lab-Created Diamonds

Liquidating or reselling a lab-created diamond can present unique challenges compared to natural diamonds, as the resale market is still developing. Options for resale include specialized online platforms or, in some cases, private sales.

Traditional jewelers and pawn shops may offer very low amounts, if they purchase them at all. When considering resale, sellers should anticipate recovering only a fraction of the original purchase price. Estimates suggest that lab-created diamonds may resell for as low as 10% to 30% of their initial retail value. This outcome is largely due to the continuous decline in wholesale prices and the absence of a robust secondary market. Setting realistic expectations regarding value recovery is crucial for anyone looking to sell a lab-created diamond.
