LAB GROWN DIAMONDS MARKET SEGMENTATION ANALYSIS
BY TYPE:
The colorless lab-grown diamonds segment dominates the market due to its strong resemblance to natural diamonds and high acceptance in fine jewelry. Consumers prioritize brilliance, purity, and traditional aesthetics, especially for engagement rings and wedding jewelry. Advancements in production technology have significantly improved the quality of colorless stones, making them nearly indistinguishable from mined diamonds while remaining more affordable. Ethical sourcing and sustainability further strengthen demand, particularly among younger, environmentally conscious buyers.
In contrast, colored lab-grown diamonds are gaining traction as fashion and customization trends rise. These diamonds appeal to consumers seeking unique, vibrant jewelry designs at accessible prices.

BY CLARITY:
The flawless and internally flawless segments are driven by premium jewelry demand where visual perfection is critical. Lab-grown diamonds can achieve exceptionally high clarity levels due to controlled growth environments. This attracts luxury brands and high-end consumers seeking pristine stones at competitive prices. Increased transparency in grading standards also boosts buyer confidence.
The very slightly included, slightly included, and included segments cater to cost-conscious consumers and industrial users. These diamonds offer functional and aesthetic value at lower price points, expanding market reach. Minor inclusions often do not impact visual appeal significantly, making them attractive for everyday jewelry. Their affordability supports volume sales and widespread adoption.
BY APPLICATION:
