A cornflower blue sapphire ring is one of the most exquisite and sought-after pieces of jewelry in the world. Known for its stunning vivid blue hue, this gemstone has captured the hearts of royalty, celebrities, and jewelry lovers for centuries.

In this article, we will explore what makes cornflower blue sapphires so special, how they are graded and valued, the best settings and metals for these rings, how to care for your sapphire ring, and why they make a perfect choice for engagement rings and special occasions.

Whether you are buying your first sapphire ring or adding to your collection, this guide will help you make an informed decision.

What is a Cornflower Blue Sapphire?

A cornflower blue sapphire is a variety of the mineral corundum, just like rubies. What makes it unique is its medium-blue color, resembling the petals of a cornflower. Unlike darker or lighter sapphires, this shade is bright, saturated, and highly desirable.

The most famous cornflower blue sapphire is the one worn by Princess Diana, now worn by Kate Middleton, which sparked global demand for this gemstone.

Key Features of Cornflower Blue Sapphires:

Color: A vivid, medium-blue tone (not too dark, not too light)

Clarity: High-quality stones have few visible inclusions

Cut: Usually oval, round, or cushion-cut to maximize brilliance

Origin: The finest come from Kashmir (India), Burma (Myanmar), and Sri Lanka

How Cornflower Blue Sapphires Are Graded

Not all blue sapphires are equal. Gemologists evaluate them based on four key factors:

Color (The Most Important Factor)

The primary color is blue, with an ideal medium tone and vivid saturation. A true cornflower blue sapphire has a pure blue hue with no green or gray undertones.

Clarity

Eye-clean sapphires with no visible flaws are the most valuable. Some inclusions are acceptable if they don’t affect brilliance.

Cut

A well-cut sapphire reflects light beautifully. Popular cuts include oval, round, cushion, emerald, and pear.

Carat Weight

Larger sapphires are rarer and more expensive. A 1-carat high-quality cornflower sapphire can cost between 2,000 and 10,000 or more, depending on origin.

Where Do the Best Cornflower Blue Sapphires Come From?

Kashmir (India) – The Rarest and Most Expensive

Known for their velvety blue color and slight silk-like inclusions, Kashmir sapphires are almost no longer mined, making them extremely valuable.

Burma (Myanmar) – Royal Blue with High Brilliance

These sapphires have a rich color, often with a slight violet undertone, and are favored by collectors and high-end jewelers.

Sri Lanka (Ceylon) – Bright and Affordable

The most common source of cornflower blue sapphires, Ceylon stones offer excellent clarity and color at a more accessible price.

Madagascar – A Rising Star

Producing beautiful blue sapphires similar to Ceylon stones, Madagascar sapphires are more affordable than those from Kashmir or Burma.

Choosing the Perfect Setting for a Cornflower Blue Sapphire Ring

The right setting enhances the sapphire’s beauty and protects it. Here are the best options:

Solitaire Setting (Classic & Elegant)

A single sapphire set in a simple band, best for platinum, white gold, or yellow gold.

Halo Setting (Extra Sparkle)

The sapphire is surrounded by diamonds, making the center stone appear larger.

Three-Stone Setting (Symbolic Meaning)

Represents past, present, and future, often featuring two diamonds flanking the sapphire.

Vintage or Art Deco Setting (Romantic & Unique)

Intricate designs with milgrain or filigree details, perfect for antique-style lovers.

Best Metals for Sapphire Rings:

Platinum: Durable, hypoallergenic, and luxurious

White Gold: Affordable alternative to platinum

Yellow Gold: Warm contrast against the blue sapphire

Rose Gold: A modern, romantic look

Cornflower Blue Sapphire Engagement Rings

Sapphires are the second most popular engagement gemstone after diamonds. Here’s why:

Symbolism

Sapphires represent loyalty, wisdom, and nobility, making them a timeless choice for a lifelong commitment.

Durability

With a 9 on the Mohs hardness scale, sapphires are almost as hard as diamonds and resistant to scratches and daily wear.

Unique & Personal

They stand out from traditional diamond rings and can be customized with different settings and side stones.

Celebrity Inspiration:

Kate Middleton’s iconic sapphire engagement ring, along with Penelope Cruz, Elizabeth Hurley, and Princess Eugenie, have popularized sapphire rings.

How to Care for Your Cornflower Blue Sapphire Ring

With proper care, your sapphire ring will last generations.

Cleaning Tips:

Warm Soapy Water: Soak for 10 minutes, then gently scrub with a soft brush

Ultrasonic Cleaner: Safe for sapphires (but avoid if the stone has fractures)

Professional Cleaning: Recommended once a year

Maintenance:

Avoid harsh chemicals like bleach and chlorine

Remove when doing heavy work like gardening or gym activities

Store separately to prevent scratches

Is a Cornflower Blue Sapphire Ring a Good Investment?

High-quality sapphires, especially from Kashmir or Burma, appreciate in value over time. Factors that increase value include natural, untreated stones, vivid color with excellent clarity, and rarity in larger sizes and top origins.

If you buy from a reputable jeweler with certification (GIA, AGL), your sapphire ring can be both a beautiful heirloom and a smart investment.

Where to Buy a Genuine Cornflower Blue Sapphire Ring

To avoid scams, follow these tips:

Buy from Trusted Sources

Reputable jewelers like Tiffany & Co., Cartier, or local certified stores, as well as auction houses like Sotheby’s and Christie’s for rare pieces.

Check Certifications

Compare Prices

If a deal seems too good to be true, it probably is. Natural cornflower blue sapphires are expensive.
