The Rise of Lab-Grown Diamonds Amidst Falling Natural Diamond Prices

As of 2025, the gold market continues to soar to unprecedented heights, while the prices of natural diamonds are experiencing a significant decline. This dramatic shift in the value of diamonds can largely be attributed to the burgeoning popularity of lab-grown diamonds, which possess identical chemical compositions and optical qualities to their natural counterparts.

Lab-grown diamonds are gaining traction as a sustainable alternative, offering buyers a unique combination of environmental responsibility and affordability. These diamonds mirror the light refractivity, hardness, and clarity of natural diamonds, making them an attractive option for consumers seeking both elegance and eco-friendliness.

Product Overview

A shining example of this new trend is “The Diamond Fruit,” a lab-grown diamond jewel offered by RAIN:

- Carat Weight: Approximately 0.5 ct
- Color: F color and up (colorless)
- Clarity: VS class and above
- Cut: RAIN’s unique frameless cut (no prongs or settings)
- Material: Lab-grown diamond
- Price: ¥20,800 (tax included)
- Includes: Certificate of quality

RAINA's “Gem Fruit” series is designed to showcase the pure brilliance of gemstones without the constraints of traditional settings. This innovative concept encourages consumers to appreciate the gem's natural sparkle and authenticity without the embellishments typically associated with traditional jewelry. RAIN has extended this series to include rubies, sapphires, emeralds, and pink diamonds, revealing a new trend in the jewelry industry.

It's crucial to note that stock for “The Diamond Fruit” is running low, and future restocking dates remain uncertain. The project's duration extends until 2025/10/26.
