Lab Diamond Tennis Bracelet in 18ct White Gold

SKU: LBL423

AUD $6,200.00 incl. GST

Want serious sparkle around your wrist? Our lab diamond tennis bracelet brings it in a big way. A line of 51 larger round lab grown diamonds runs unbroken around the wrist, set in cool 18ct white gold so every stone looks extra white and bright. With a generous 5.28ct in total, this is a bold, glamorous take on the classic tennis bracelet, throwing fire with every turn of the wrist. Wear it solo to let those bigger diamonds shine, or stack it beside a watch for full glamour. Timeless yet striking, this is the piece that turns heads and never leaves your wrist.

Why does this bracelet dazzle so much? Bigger diamonds, beautifully set. Each stone is a round brilliant, the most fiery cut there is, and at 5.28ct across 51 diamonds, every one has real size and presence. The four claw setting lifts each diamond high so light floods in from every angle, while the white gold keeps the focus on the stones. A secure box clasp holds it all safely and comfortably. As a result, it feels luxurious and substantial, the kind of bracelet that reads as a true statement piece.

We craft this lab diamond tennis bracelet in 18ct white gold and set every lab grown diamond by hand. The stones grade F in colour, so they look bright and white, and VS in clarity, clean to the eye. So you get a bold line of larger diamonds and remarkable value, since lab grown diamonds offer the same sparkle as mined stones for far less.

Features:

  • Gemstone: 51 round brilliant lab grown diamonds, 5.28ct total, F colour, VS clarity
  • Accent Stones: None
  • Metal: 18ct white gold (also available in 18ct yellow and rose gold on request)
  • Style: Continuous line tennis bracelet with larger diamonds in a four claw setting and a secure box clasp, sizing available on request

How to Style Your Lab Diamond Tennis Bracelet

Here is the fun part, because a tennis bracelet goes with everything. Wear it solo so the larger diamonds take centre stage, or stack it beside a watch and a plain gold bangle for a layered, glamorous wrist. Then echo the diamonds with a pair of diamond stud earrings for an elegant, coordinated look. Love the tennis style? Browse our tennis bracelets range to compare carat weights and find your perfect line of light. Keep your metals in the same white gold family for a crisp, cohesive finish. Want more styling ideas?

Why Buy This Lab Diamond Tennis Bracelet

So, why this bracelet? First, the size. Larger diamonds totalling 5.28ct give bold, all over wrist brilliance. Second, the value. F VS lab grown diamonds give you top quality and generous carats for a fraction of a mined line, so your budget goes much further. Third, the versatility. It dresses up an evening look and lifts an everyday one, so you will wear it constantly.

And why choose Ernesto Buono Fine Jewellery? Because we care about every detail, from the grade of each diamond to the security of the clasp. We make jewellery to be worn and loved, not locked away. Keen to see it sparkle in person and check the fit? Book an appointment and come say hello.

Your Lab Diamond Tennis Bracelet Questions, Answered

Are lab grown diamonds real diamonds?

Yes, completely. A lab grown diamond is a real diamond, with the exact same chemical, physical, and optical properties as one mined from the earth. The only difference is the origin, since it is grown in a controlled setting rather than dug from the ground. So it sparkles identically, tests as a real diamond, and lasts just as long. Why choose lab grown? Value, mostly. You get more carats and higher grades for your budget, like this generous 3.71ct line of F VS diamonds, for far less than an equivalent mined bracelet. Many people also love the modern, traceable story behind them. Real brilliance, simply made differently.

What do the specs 5.28ct, F colour and VS clarity mean?

Good question, since these grades decide a lot. The 5.28ct is the combined weight of all 51 diamonds, a generous total that gives this bracelet bold, all over sparkle and noticeably larger stones than a lighter line. F colour sits near the very top of the colour scale, so the diamonds look bright and white with no yellow tint, especially crisp in white gold. VS stands for very slightly included, near the top of the clarity scale, meaning any natural marks are so tiny you would struggle to spot them even under magnification. In short, top grades, generous carats, and serious shine.

What is a tennis bracelet, and why the name?

A tennis bracelet is a flexible line of diamonds set in a row all the way around the wrist, with no break in the sparkle. The name has a charming origin. Back in 1987, tennis champion Chris Evert was playing a match when her diamond line bracelet slipped off, and she asked officials to pause the game so she could find it. The bracelet style has been called a tennis bracelet ever since. So you are wearing a true classic with a bit of history. This one features 49 diamonds in cool 18ct white gold, a timeless design that never dates.

How does it fit, and can the length be adjusted?

A tennis bracelet should sit comfortably with a little movement, draping gently around the wrist rather than gripping tight. To check your size, measure your wrist with a soft tape just below the wrist bone, then add a little room for comfort. We can adjust the length by adding or removing diamond links, so the bracelet fits you just right, and we will make sure the secure box clasp sits snug. So whether your wrist is petite or fuller, we tailor it to fit. Pop in and we will measure you properly, since a good fit keeps it both comfortable and safe.

How do I clean and care for my tennis bracelet?

Easy, and the kit is already at home. Soak the bracelet for ten minutes in warm water with one drop of dishwashing liquid, then gently brush along the diamonds with a soft toothbrush to lift the film that dulls sparkle, including behind each stone. Rinse, but pop the plug in first, then pat dry with a soft cloth. Do this every fortnight, and keep it away from bleach, chlorine, and perfume. Because a tennis bracelet is worn often, bring it in once a year so we can check the clasp and the setting of each diamond, keeping every stone secure for the long haul.
