Double the brilliance, double the statement. This striking Moi et Toi (Me and You) engagement and cocktail ring pairs a timeless, colorless round brilliant lab diamond with a dazzling, high-saturation Fancy Vivid Pink lab-grown diamond. Perfectly contrasting classic fire with a bold shot of contemporary color, this ring is crafted for those who want an alternative engagement ring that breaks tradition without sacrificing luxury. Made in the UK, this ring is one-of-a-kind. 

Key Features

The Stones: Features one hand-selected, round brilliant cut lab diamond alongside a breathtaking radiant-cut Fancy Vivid Pink lab-grown diamond.

White Lab Diamond: 1.58ct | D Color (Colorless) | VVS2 Clarity | Ideal Cut

Radiant Lab Pink Diamond: 1.29ct | Fancy Vivid Pink | VS1 Clarity | Excellent Cut

The Color Profile: A true collector's hue—the fancy vivid pink stone boasts such deep, rich color saturation that it flirts beautifully on the exact boundary of a rare red diamond.

The Setting: Expertly claw-set in sleek, platinum on a minimalist, slim band designed to make the stones floating masterpieces. This snuggle fit means the ring will sit perfectly with another band if you want to stack it with a wedding or eternity ring. 

Ethical Luxury: certified lab diamonds delivering premium optical brilliance at a fraction of the cost of mined fancy colored stones.

Why Choose a Fancy Vivid Pink Lab Diamond?

In the world of mined gemstones, a deeply saturated pink diamond of this caliber is an unobtainable museum-piece. Our precision-grown colored lab diamonds allow you to own the exact same physical, chemical, and optical luxury. The radiant cut maximizes the internal light reflections, throwing off a deeply saturated, fiery crimson-pink flash that captures the room's attention instantly.

Perfect For: Unique engagement rings, custom anniversary gifts, or modern statement jewelry.
