GIA Shares Tips for Maintaining Ruby Heirloom Brilliance

That captivating crimson glow in your cherished ruby jewelry — once vibrant as a sunrise — may gradually lose its luster without proper care. As symbols of refined taste, emotional significance, and family heritage, rubies deserve meticulous attention to maintain their timeless beauty through generations.

Rubies possess exceptional longevity when untreated or properly enhanced. This endurance stems from two fundamental properties:

With a Mohs hardness rating of 9 — second only to diamonds — rubies demonstrate remarkable resistance to surface abrasions. The scale measures mineral hardness through comparative scratch tests, though the progression isn't linear. While diamonds rate just one point higher, their actual hardness significantly exceeds corundum gems like rubies.

Beyond hardness, rubies boast impressive toughness — resistance to chipping or breaking. Unlike minerals with cleavage planes that fracture along specific directions, rubies maintain structural integrity against impacts, making them ideal for daily-wear jewelry.

Rubies exhibit excellent resistance to common environmental factors:

• Heat: Stable under normal temperature variations but vulnerable to sudden extreme changes
• Light: Resistant to fading, though prolonged intense exposure may affect treated stones
• Chemicals: Generally inert but sensitive to boric acid and certain cleaning agents

Proper maintenance varies by treatment type:

For untreated or heat-treated rubies:

• Warm soapy water with soft bristle brushing
• Ultrasonic cleaners (with caution)
• Steam cleaning (professional recommended)

Fracture-filled or dyed rubies demand gentler methods:

• Damp cloth wiping only
• Avoid all chemical cleaners
• Never use ultrasonic devices

• Heat Treatment: Enhances color naturally without durability compromise
• Lattice Diffusion: Color penetration varies — shallow treatments risk surface damage
• Fracture Filling: Lead-glass filled rubies require extreme caution with acids and chemicals

• Remove jewelry during household cleaning, swimming, or strenuous activities
• Store separately in soft pouches to prevent scratches
• Schedule annual professional inspections for prong security and stone integrity
• Avoid exposure to cosmetics, hair products, and perfumes

With informed care, rubies can transcend generations as luminous family heirlooms, their fiery beauty undiminished by time. Proper maintenance preserves not just a gemstone's physical attributes, but the memories and legacy it carries forward.
