Radiant Cut Studs in 18ct White Gold

SKU: LER0026

AUD $1,960.00 incl. GST

After a pair of diamond studs with real presence and a modern edge? Our radiant cut studs are exactly that. Each earring holds a single radiant cut lab grown diamond, around half a carat, for 1.03ct across the pair, held in a secure four claw setting in bright 18ct white gold. So a big, brilliant diamond sits in each ear, its crisp rectangular shape and sparkling facets catching the light from every angle. The radiant cut blends the clean outline of an emerald cut with the fire of a round, so you get bold shape and serious sparkle in one. Striking, elegant, and endlessly wearable, these are the studs that lift any outfit, day or night.

Why choose the radiant cut? Its faceting and its shape. A radiant is cut with dozens of brilliant facets, so it sparkles intensely like a round diamond, yet it keeps a striking rectangular outline with softly trimmed corners. That gives these studs a clean, contemporary look with plenty of fire, a little more distinctive than a classic round stud. The simple four claw setting lifts each diamond up to the light and shows off its full shape, while the white gold keeps everything crisp and cool. As a result, the studs feel modern, luxurious, and beautifully balanced on the ear.

We craft these radiant 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 real diamonds, real gold, and remarkable value, since lab grown offers the same beauty as mined stones for far less.

Features:

  • Gemstone: 2 radiant cut lab grown diamonds, 1.03ct total, around 0.5ct each
  • Accent Stones: None
  • Metal: 18ct white gold
  • Style: Four claw radiant cut solitaire studs on butterfly backs, sold as a pair

Here is the fun part, because studs go with everything. Explore our earrings to see the full range, then compare them with our other stud earrings to find your perfect pair. These radiant studs are bold enough to wear 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 with yellow gold too for a mixed metal look. Want more inspiration?

Your Radiant Cut Studs Questions, Answered

What is a radiant cut diamond?

A radiant cut is a rectangular or square diamond with softly trimmed, or cropped, corners and dozens of brilliant facets. That faceting is the key, since it makes a radiant sparkle intensely like a round brilliant, while keeping a bold, geometric outline. So it is often described as the best of both worlds, the crisp shape of an emerald cut with the fire of a round. The trimmed corners also make it durable and comfortable to wear. On a pair of studs, that means plenty of sparkle in a clean, modern shape. It is a striking, contemporary choice that stands apart from the classic round stud.

How big are these studs?

They make a confident statement. Each earring holds a radiant cut diamond of around half a carat, so the pair totals 1.03ct of diamond. That is a lovely, noticeable size for studs, big enough to catch the eye and sparkle across a room, while still sitting comfortably and securely on the ear. Because the radiant cut is rectangular, each stone also covers a good amount of surface area, so it looks generous face on. 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.

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. You get bigger, higher grade diamonds for your budget, like this bright 1.03ct pair, for far less than an equivalent mined pair. So it is real brilliance and real gold, simply made in a smarter, more affordable way.

Are these studs good for everyday wear?

Yes, they are lovely for it. The studs sit neatly against the ear and fasten with a secure butterfly back, so they are comfortable to wear all day and easy to put on. Because they are diamond and 18ct white gold, they cope with daily life beautifully and will not tarnish. So you can wear them to work, out to dinner, and everywhere in between. As with any fine jewellery, take them out for the shower, the gym, and swimming to keep them bright, and give them a quick clean now and then. They really are a versatile pair you can wear again and again.

Why choose white gold for radiant cut studs?

White gold is a beautiful match for a radiant cut diamond. Its cool, silvery tone sits quietly behind the stone and lets the diamond be the star, so the sparkle and the crisp shape stand out rather than the metal. White gold also has a clean, modern feel that suits the geometric radiant cut perfectly, and it 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 diamonds to look as bright and white as possible, white gold is a lovely, versatile choice.
