Round Cut Studs in 18ct White Gold

SKU: LER0038

AUD $2,580.00 incl. GST

After a pair of diamond studs with serious presence? Our round cut studs are exactly that. Each earring holds a single round brilliant lab grown diamond of around one full carat, for a generous 2.05ct across the pair, held in a secure four claw setting in bright 18ct white gold. So a big, brilliant diamond sits in each ear, blazing with fire and light with every move. Round cut studs are the ultimate classic, and at this size they make a real statement, the pair that turns heads yet still goes with absolutely everything. Timeless, dazzling, and beautifully wearable, these are the studs for a milestone moment, a gift to remember, or a treat you will never take off.

Why is the round brilliant so loved? Its sparkle. The round brilliant is cut with 57 or 58 perfectly angled facets, engineered to reflect the most light possible, so it is the most fiery, dazzling diamond shape there is. At around a carat each, these stones have real size and throw enormous sparkle, in a clean, classic circle that suits everyone and every outfit. The simple four claw setting lifts each diamond up to the light and holds it securely while showing off as much of the stone as possible, and the white gold keeps everything crisp and cool. As a result, these studs are as brilliant as they are versatile.

We craft these round cut studs in 18ct white gold and set each lab grown diamond by hand. The two diamonds are matched for cut, colour, and sparkle, so both studs glitter evenly and brightly. So you get large, top quality diamonds, real gold, and remarkable value, since lab grown makes a pair this size possible for a fraction of a mined equivalent.

Features:

  • Gemstone: 2 round brilliant lab grown diamonds, 2.05ct total, around 1.0ct each
  • Accent Stones: None
  • Metal: 18ct white gold
  • Style: Four claw round brilliant solitaire studs on butterfly backs, sold as a pair

At this size, round cut studs make a statement on their own, and they also look striking stacked above a hoop or a second piercing. The white gold pairs beautifully with both silver toned and white gold pieces, and looks lovely mixed with yellow gold for a modern two tone look. Want more inspiration?

Your Round Cut Studs Questions, Answered

How big are these studs?

They make a real statement. Each earring holds a round brilliant diamond of around one full carat, so the pair totals a generous 2.05ct of diamond. That is a big, eye catching size for studs, the kind that sparkles across a room, while the round shape keeps them classic and easy to wear every day. Around a carat in each ear feels luxurious yet still comfortable and secure. If you would prefer a larger or smaller pair, just ask, since we can make this style up in different diamond sizes to suit your taste and budget, from dainty everyday studs to real showpieces.

Are the diamonds natural or lab grown?

These are lab grown diamonds. 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 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. It is what makes a large 2.05ct pair like this achievable at this price, when a mined equivalent would cost many times more. So you get real brilliance and real gold, with impressive size, for remarkable value.

Why is the round brilliant cut so popular?

Because it sparkles more than any other shape. The round brilliant is cut with 57 or 58 precisely angled facets, all designed to bounce light back up through the top of the stone, so it has more fire and brilliance than any other diamond cut. That is why it is the most loved and most classic shape for studs. It also suits everyone, since a simple round diamond is timeless and never dates, and it works with every outfit and occasion. So if you want maximum sparkle in an elegant, versatile pair, especially at this generous size, the round brilliant is the perfect choice.

Are these studs practical to wear every day?

Yes, with a little care they wear beautifully. Even at around a carat each, the studs sit neatly against the ear and fasten with a secure butterfly back, so they are comfortable for all day wear. Because they are diamond and 18ct white gold, they cope with daily life well and will not tarnish. Many people wear studs this size every day, while others save a larger pair for special occasions, so it comes down to you. Take them out for the shower, the gym, and swimming to keep them bright, and give them a quick clean now and then to keep them sparkling.

Why choose white gold for round cut studs?

White gold is a beautiful match for a round diamond. Its cool, silvery tone sits quietly behind the stone and lets the diamond be the star, so the sparkle and fire stand out rather than the metal, which is especially striking at this size. White gold also has a clean, modern feel and pairs easily with both silver toned and white gold pieces you already own. On top of that, it flatters every skin tone and works day or night. So if you want your large diamonds to look as bright and white as possible, white gold is a lovely, versatile choice.
