WHAT ARE NATURAL BLUE SAPPHIRES?

WHAT IS A CEYLON SAPPHIRES?

 

  • Ceylon sapphires refer to natural sapphires mined from Sri Lanka (formerly known as Ceylon). These gemstones are celebrated for their exceptional brilliance, clarity, and lighter yet vivid blue hues.
    Unlike darker sapphires from other regions, Ceylon sapphires have a luminous quality that allows light to pass beautifully through the stone, making them a favorite among collectors and fine jewelers worldwide.

WHAT IS A ROYAL BLUE SAPPHIRES?

 

  • A Royal Blue sapphire is known for its deep, velvety blue color — rich, intense, and evenly saturated. This luxurious hue is considered the “ideal blue” for fine jewelry and is often found in high-end gemstones from Sri Lanka, Kashmir or Myanmar (Burma)

  • Its regal tone symbolizes nobility, wisdom, and power — famously worn by royals, including Princess Diana’s iconic engagement ring.

WHAT ARE CORNFLOWER BLUE SAPPHIRES?

 

  • Cornflower Blue sapphires are prized for their soft, medium-light blue color with a slight violet undertone — reminiscent of the delicate cornflower blossom. These sapphires, especially from Kashmir and Sri Lanka, are treasured for their vivid yet soft tone, often described as “pure” blue without being too dark or pale.

  • Collectors value them for their gentle, romantic color balance — ideal for elegant, timeless jewelry.

WHAT ARE PALE BLUE SAPPHIRES?

 

  • Pale Blue sapphires display a lighter, icy blue tone that feels fresh and subtle. Though less saturated, these sapphires have an airy brilliance and are often chosen for minimalist jewelry or pastel-inspired engagement rings.

  • Their understated elegance makes them an affordable and graceful choice for those who prefer delicate hues over deep saturation.

WHAT ARE VIVID BLUE SAPPHIRES?

 

  • Vivid Blue sapphires showcase the most intense and lively blue tone within the sapphire spectrum. Their color is rich, electric, and full of energy, with superior light reflection and saturation.

  • Stones in this category are extremely rare, especially when combined with high clarity and size. They make stunning centerpieces for engagement rings and statement jewelry.

WHAT ARE NATURAL SAPPHIRES?

 

  • A Natural sapphire is a gemstone formed in the Earth over millions of years without any synthetic or lab-created processes. Many natural sapphires undergo gentle heating to enhance clarity or color — a common and accepted treatment in the gem trade.

ARE YOUR BLUE SAPPHIRES TREATED?

HOW DO I CARE FOR MY BLUE SAPPHIRE?

 

  • Clean with warm soapy water and a soft brush. Avoid harsh chemicals and store separately to prevent scratching other jewelry. Regular gentle care will preserve the sapphire’s brilliance for years.
