A Love Story Told in Blue and White

There’s something undeniably majestic about a sapphire diamond engagement ring. It’s not just the stunning contrast of deep blue and brilliant white—it’s the romance, history, and individuality wrapped into one extraordinary piece.

If you’re looking for a ring that says “classic” but with a bold twist, sapphires and diamonds together are a match made in heaven. Whether you’re after timeless elegance or a pop of personality, this combo offers the best of both worlds.

Why Choose a Sapphire Diamond Engagement Ring?

It’s Not Just Beautiful—It’s Meaningful

Sapphires have long been linked to loyalty, wisdom and truth. In ancient times, they were believed to protect lovers from envy and harm. Today, they make a heartfelt symbol of trust, strength and everlasting love.

Pair that with diamonds—symbols of eternity and purity—and you’ve got a ring with serious emotional weight.

A Royal Favourite

Let’s not forget, the most famous engagement ring in the world is a sapphire and diamond masterpiece. Princess Diana’s (and now Kate Middleton’s) iconic Ceylon sapphire ring sparked a global love affair with this regal gem.

Design Options That Shine

H2: The Classic Oval Sapphire with Diamond Halo

An oval sapphire framed by a halo of round diamonds is an all-time favourite. It enhances the stone’s brilliance and gives it a vintage-meets-modern vibe—ideal for someone who loves elegance with a touch of glamour.

H3: Three-Stone Rings

A centre sapphire flanked by two sparkling diamonds offers a balanced and romantic design. Each stone can represent your past, present and future—a meaningful choice for couples who love symbolism.

H4: Art Deco Inspiration

For those who crave something bold, geometric and eye-catching, Art Deco designs combine sapphires, diamonds, and angular shapes in a way that’s truly unforgettable.

Choosing the Right Sapphire

Not all sapphires are created equal. Here’s what to keep in mind:

Colour is Queen

The most valuable sapphires have a rich, velvety blue hue, often referred to as “royal blue” or “cornflower blue”. But sapphires also come in pink, yellow, and peach—so if you want to veer off the beaten path, you absolutely can.

Origin Matters

Ceylon (Sri Lankan) and Kashmir sapphires are world-renowned for their quality. At Ernesto Buono, we source only ethical, certified stones from trusted suppliers.

Cut and Clarity

Like diamonds, sapphires need an expert cut to maximise their brilliance. While some inclusions are normal, aim for stones that are eye-clean, especially in larger sizes.

Diamonds: The Perfect Companion

Pairing diamonds with sapphires creates a dazzling contrast. Here are a few popular pairings:

• Pavé-set diamonds on the band for extra sparkle

• Halo of diamonds around a sapphire centre stone

• Side baguette or trillion-cut diamonds for a sleek modern twist

Each option adds elegance without overpowering the star of the show—your sapphire.

Durability and Daily Wear

Good news: Sapphires are incredibly durable—ranking 9 on the Mohs hardness scale, just below diamonds. That means they’re perfect for daily wear and long-lasting love stories.

To keep your ring looking pristine:

• Clean it regularly with mild soap and warm water

• Avoid harsh chemicals and ultrasonic cleaners

• Schedule occasional professional cleanings and prong checks
