Lab Diamond Bracelet in 18ct Yellow Gold

SKU: LBL439

AUD $2,000.00 incl. GST

After a bracelet you can wear every single day and never want to take off? Our lab diamond bracelet is exactly that. A single 0.55ct emerald cut lab grown diamond floats at the centre of a fine 18ct yellow gold chain, set on its side in a smooth rubover setting so it sits flush and secure. So one beautiful diamond catches the light on your wrist, understated yet full of sparkle, in warm, everyday gold. Delicate, elegant, and effortlessly wearable, this is the piece that goes with everything, layers beautifully, and makes a lovely gift for yourself or someone special. Simple, modern, and quietly luxurious.

Why does this bracelet feel so special? Its simplicity. A single diamond on a fine chain is the definition of everyday elegance, a piece you can dress up or down and truly live in. The emerald cut, with its clean rectangular shape and stepped facets, gives a beautiful, clear window into the stone, and setting it east west, lying sideways along the chain, feels modern and chic. The rubover setting wraps the diamond in a slim band of gold, so it is protected and snag free, perfect for daily wear. A secure lobster clasp keeps it safely on. As a result, the bracelet is as practical as it is pretty.

We craft this lab diamond bracelet in 18ct yellow gold and set the lab grown diamond by hand. The 0.55ct emerald cut stone is chosen for its bright, clear sparkle. So you get a real diamond, real gold, and remarkable value, since lab grown offers the same beauty as a mined stone for far less.

Features:

  • Gemstone: Emerald cut lab grown diamond, 0.55ct, rubover set east west
  • Accent Stones: None
  • Metal: 18ct yellow gold (also available in 18ct white and rose gold on request)
  • Style: Single diamond on a fine cable chain with a lobster clasp, sizing options available

How to Style Your Lab Diamond Bracelet

Here is the fun part, because a bracelet loves company. Explore our bracelets to build a stack, then see how it sits beside a delicate chain bracelet for an easy, layered look. This piece is perfect worn alone for understated sparkle, or stacked with a bangle or a tennis bracelet for more shine. The yellow gold pairs beautifully with both warm and cool tones, so wear it with whatever you already love. It also makes a lovely everyday gift. Want more inspiration?

Your Lab Diamond Bracelet Questions, Answered

Is the diamond real?

Yes, completely. This is a lab grown diamond, and a lab grown diamond is a real diamond, with the exact same chemical, physical, and optical properties as one mined from the earth. So it sparkles identically, tests as a real diamond, and lasts just as long. The only difference is the origin, since it is grown in a controlled setting rather than dug from the ground. Why choose lab grown? Value, mostly. You get a bright, real 0.55ct diamond for far less than a mined stone, which makes an everyday diamond bracelet like this wonderfully affordable.

What is a rubover setting?

A rubover setting, sometimes called a bezel setting, is when a slim band of gold wraps all the way around the edge of the diamond, holding it securely in place. Rather than claws, a smooth rim of metal hugs the stone. Why is that good for a bracelet? It protects the diamond, keeps the edges tucked away so nothing snags on clothes or hair, and gives a sleek, modern look. That makes it perfect for a piece you wear every day, since it is both secure and comfortable. So your diamond stays safe and looks beautifully clean and contemporary, floating on the fine chain.

What size is the diamond, and will it be noticeable?

The diamond is a 0.55ct emerald cut, which is a lovely size for an everyday bracelet. It is dainty and elegant rather than large and showy, so it sits comfortably on the wrist and works with any outfit, yet it still catches the light and draws the eye. Because it is an emerald cut, it has a clean, open shape that shows off a clear, bright sparkle. So it gives you real diamond presence in a delicate, wearable form. If you would like a larger or smaller stone, just ask, since we can make this style up in different sizes to suit you.

Will this bracelet fit my wrist, and can it be adjusted?

Yes, we will make sure it fits you beautifully. A chain bracelet should sit comfortably with a little movement, resting just below the wrist bone. If you need it shorter or longer, we can adjust the chain to your exact size, and many chains can include an extra jump ring so you can vary the length slightly yourself. It fastens with a secure lobster clasp that is easy to use and holds firmly. So just come in or get in touch, and we will size it so it feels just right and sits perfectly on your wrist every time you wear it.

Is this bracelet good for everyday wear?

Yes, it is designed for it. The single diamond sits in a smooth rubover setting that protects the stone and will not snag, and the fine 18ct gold chain is both delicate and durable. Because it is diamond and solid gold, it copes with daily life beautifully and will not tarnish. So you can wear it to work, out to dinner, and everywhere in between, and layer it with other bracelets whenever you like. As with any fine chain, take it off for the gym, heavy tasks, and swimming to protect it, and it will keep sparkling for years to come.
