Frequently Asked Questions

What makes a diamond solitaire necklace special?

A diamond solitaire necklace showcases one diamond as the centerpiece, highlighting its natural brilliance and sparkle without distraction. It’s a design that works beautifully for both daily wear and formal occasions.

Can I wear a diamond solitaire necklace every day?

Yes. Solitaire necklaces are crafted for adaptability and comfort. The diamond is securely set, often in a prong or bezel setting, to ensure long-lasting wear without compromising brilliance or style.

How do I choose the right carat size for a solitaire diamond pendant necklace?

Smaller carat weights like 0.25–0.5 ct are subtle for everyday wear, while 1 ct or larger offers a unique and bold appearance. James Allen’s 360° diamond view helps you visualize how each size appears before you buy.

Are diamond solitaire necklaces suitable for layering?

Absolutely. Their simple silhouette makes them perfect for layering with other chains or pendants. Try pairing a solitaire diamond pendant necklace with shorter gold chains or a choker necklace for a chic, modern layered look.

How should I clean and maintain my necklace?

Clean your necklace with a mild soap solution and a soft brush to keep the diamond sparkling. Avoid harsh chemicals and store them separately to prevent scratches.
