18-Inch Diamond Circle Duet Layered Necklace

Natural vs. Lab-Created Diamonds

We carry both natural and lab-created diamonds, so you can pick whichever fits your priorities. Natural diamonds formed underground over billions of years. Every stone is one of a kind, with its own character and story. Lab-created diamonds are grown in a controlled setting using the same conditions that create natural diamonds. Chemically and visually, they're identical to mined stones.

Both types get graded on the same 4Cs scale (Cut, Color, Clarity, Carat), and both sparkle the same way. The decision usually comes down to what matters most to you: the history and rarity of a natural diamond, or the value and traceability of a lab-grown one. Either way, you're getting a real diamond.

• Natural Diamonds: Formed over billions of years, rare, each stone is unique
• Lab-Created Diamonds: Same physical properties, traceable origin, better price point
• Grading: Both graded identically using Cut, Color, Clarity, and Carat
• Bottom Line: Pick based on what matters to you, not what anyone else thinks

Your Options

Diamond necklaces run the range from barely-there to impossible-to-miss. A simple solitaire pendant is understated and wearable daily. Station necklaces space diamonds along the chain for subtle sparkle all around. Riviera styles graduate the stones larger toward the center. Collars and chokers make more of a statement.

• Solitaire Pendant: One diamond, endlessly wearable
• Diamond Station: Spaced out for all-around sparkle
• Riviera/Graduated: Bigger stones in the center draw the eye
• Collar/Choker: Sits high, makes an entrance
• Y-Necklace: Dips down, lengthens your neckline

What Length Works for You?

Length changes everything about how a necklace looks. Think about what you usually wear and where you want the necklace to sit. Shorter lengths work with lower necklines. Longer ones layer well or work under a collar. Your height and neck length matter too.

• 14-16 inches: Choker length, sits close to the neck
• 17-19 inches: Falls at the collarbone, most common choice
• 20-24 inches: Lands lower, between collarbone and chest
• 28-34 inches: Long enough to double up or layer

Choosing the Metal

White metals like platinum and white gold blend seamlessly with diamonds—the metal disappears and the stones stand out. Yellow gold creates contrast and warmth. Rose gold adds a modern, warm tone. Think about what you already own and what looks good on your skin.

• Platinum: Strongest, naturally white, won't irritate skin
• White Gold: More affordable, needs replating over time
• Yellow Gold: Traditional, hides lower color grades
• Rose Gold: Trendy, works on most skin tones

Taking Care of It

Diamonds are tough, but necklaces need some looking after. Clean yours regularly—soap and water does the trick. Store it where it won't tangle with other pieces. Put it on after you're done with hairspray and perfume. Get the clasp and settings checked once a year.

• Clean monthly with mild soap and a soft brush
• Store hanging or flat, away from other jewelry
• Put it on last, after makeup and perfume
• Have the clasp and settings checked yearly
• Consider insurance for expensive pieces

When to Wear It

Diamond necklaces work pretty much anywhere—it's about picking the right one. A small pendant is fine for the office or running errands. Something more substantial dresses up date night. For weddings and galas, go as bold as you want. The piece should match the event.

• Every day: Small pendant or delicate station chain
• Work: Keep it simple and subtle
• Date night: A little more sparkle, halo or Y-style
• Formal events: Riviera or collar makes an impression
• Weddings: Elegant drop or classic pendant
