How some of the most vibrant diamonds get their glow ?
Irradiation Can Turn Ordinary Diamonds Electric Blue
By exposing diamonds to high-energy radiation, jewelers can transform their colour—often into brilliant blues or greens. These diamonds are safe to wear, but the idea of radiation still makes some buyers pause.
HPHT Treatment Mimics Nature in a Lab
High Pressure, High Temperature (HPHT) treatment simulates the extreme conditions under which natural diamonds form. The result? Stunning colour upgrades. Still, some collectors hesitate, fearing it reduces the gem’s authenticity or resale value.
Coated Diamonds Are Pretty—But Not Forever
A thin film applied to the surface can enhance a diamond’s colour instantly. But be warned—coatings can fade or wear off, especially with everyday wear, leaving the diamond looking quite different over time.
What You Need to Know Before Buying One
Colour-enhanced diamonds can be beautiful and budget-friendly alternatives to rare fancy colours. Just make sure you know which treatment was used—and how permanent it really is.
