-- FREQUENTLY ASKED QUESTIONS --

Q: How does Swiss Blue compare to other topaz varieties?
A: Topaz naturally occurs in multiple blue intensities. Swiss Blue is the vibrant middle tier—noticeably deeper and more saturated than pastel Sky Blue, yet far lighter and more electric than dark, steely London Blue.

Q: How is this gem treated to achieve its color?
A: Natural clear topaz mined from the earth undergoes a permanent, industry-standard heat and irradiation process. This activates latent color centers within the crystal lattice, permanently locking in its saturated tone without fading over time.

Q: Is this stone suitable for everyday wear?
A: With an 8 on the Mohs hardness scale, topaz resists scratching better than quartz, glass, or opal. While durable for daily use, sharp impacts against hard surfaces should still be avoided along its natural cleavage planes.

Q: Which chain length should I choose for this pendant?
A: 18 inches is our most popular length and fits most necklines. Here is how each length sits:

• 16 INCHES: Collarbone length; ideal for open, petite, or lower necklines.
• 18 INCHES: Just below the collarbone; the standard length for everyday wear and gifting.
• 20 INCHES: Low collarbone / chest area; pairs well with crew necks and sweaters.
• 24 INCHES: Mid-chest drape; perfect for layering with shorter necklaces.

Q: What is 14K Gold-Filled and how does it compare to standard gold plating?
A: Governed by FTC standards, 14K gold-filled jewelry is crafted with a heavy outer layer of genuine 14K gold—accounting for at least 5% (1/20th) of the item's total weight—mechanically bonded to a proprietary alloy core. Because this gold layer is significantly thicker than standard electroplating, it resists tarnishing, maintains its luster over time, and provides hypoallergenic wear suitable for sensitive skin.

-- STYLE TIP --

The bright azure tone provides an effortless focal point against neutral wardrobes, especially crisp white, camel, slate gray, and navy. Choose yellow gold for warm, sunlit contrast or sterling silver for a clean, tonal finish.
