Colourless diamonds have always meant timeless. But today's buyers want jewellery that feels personal too, and colour is leading that shift.
Pink, yellow, blue and green lab grown diamonds are showing up everywhere, from engagement rings to everyday stacks, and they carry the same brilliance and durability as any colourless diamond. Here's what's behind the trend, and how to choose your own.
What Are Coloured Lab Grown Diamonds?
A coloured lab diamond is still a real diamond, same crystal structure, same hardness, same fire as a colourless stone. Colour develops during the growth process itself, through trace elements like nitrogen or boron, or subtle shifts in the crystal lattice. Every Leeba stone comes IGI certified, confirming origin, carat, clarity, cut and colour.
Why Everyone's Choosing Colour
• Adding personality to day to day life, not just special-occasion jewellery
• Engagement rings that feel personal, not predictable
• Celebrity and red carpet visibility
• Social media making colour easy to discover and style
• Accessible pricing compared to rare natural fancy diamonds
Pink, Yellow, Blue, Green: A Quick Guide
Pink reads romantic and bold at once, perfect for a center stone or stacked studs. Yellow brings warmth with a vintage edge, glowing in yellow or rose gold. Blue is cool and modern, a striking alternative for engagement rings, especially in white gold or platinum. Green is the rarest of the four, nature-inspired, and best left to stand alone in a fresh, contemporary setting. Champagne, orange and teal diamonds are worth a look too, for something a little different.
The Pink, Yellow, Blue and Green Diamond Rings
Four colours tend to capture attention before any other, and each has earned its own following for a different reason.
Pink Lab Grown Diamond Ring
Pink rings carry a soft, romantic presence that still manages to feel bold, especially in a pear or oval cut surrounded by a double halo. The look draws inspiration from some of the most recognisable pink diamond rings worn on red carpets, where a vivid pink centre stone against white diamond accents has become an instantly iconic silhouette. It is a popular choice for engagement rings precisely because it feels both timeless and fashion forward at once, more expressive than a classic white solitaire without losing any of its elegance.
One of the most recognizable examples is Anna Kournikova, whose iconic pink pear-shaped diamond ring became globally admired for its bold yet elegant presence. The soft pink hue combined with the dramatic pear silhouette created a completely different personality compared to traditional white diamond solitaires — more expressive, fashion-forward, and unforgettable
Inspired by this same modern luxury aesthetic, we created our
Vivid Pink Pear Cut Double Halo Solitaire Ring a statement piece designed to capture the elegance, femininity, and brilliance that made pink diamonds one of the most desired jewellery trends globally. The elongated pear silhouette combined with the vivid pink centre stone and double halo detailing creates a ring that feels both timeless and fashion editorial at the same time.
Yellow Lab Grown Diamond Ring
Yellow rings bring warmth and a quiet confidence, often set as a cushion or radiant cut to let the colour catch the light. The style nods to the fancy yellow diamonds long favoured by style icons for their golden, sunlit glow, paired beautifully with yellow or rose gold for a cohesive, vintage inspired finish. A yellow diamond ring tends to suit buyers who want a statement that still feels wearable every day, vibrant without being loud.

The yellow diamond is estimated to be over 10 carats, a significant piece among her famously varied engagement rings.
Blue Lab Grown Diamond Ring
Blue rings have a cool, contemporary edge that instantly sets them apart from a traditional white diamond solitaire. Set in white gold or platinum, a blue diamond centre stone reads as confident and modern, often chosen by buyers who want their engagement ring or statement piece to feel distinctly their own. The deeper the saturation, the bolder the result, while paler icy blues keep the look softer and more wearable day to day.
In our version of Blake’s ring, look at how beautifully the cool hue of the blue sapphire center stone complements the warm glow of the rose gold setting. The color also more clearly defines the oval shape, which gives the desirous effect of a longer and slimmer finger. As such, the ring is at once glamorous and trendy, perfectly suited to the stylish star.
Green Lab Grown Diamond Ring
Green rings remain the rarest of the four, and that rarity is exactly the appeal for buyers seeking something genuinely unexpected. A nature inspired, mossy to vivid green centre stone works best in a clean, contemporary setting where the colour is left to stand on its own, making it a favourite among those who want their jewellery to start a conversation rather than blend in.
