Lab Grown Diamond Studs in 18ct Yellow Gold

SKU: LER0044

AUD $2,800.00 incl. GST

After a pair of diamond studs with real presence and remarkable value? Our lab grown diamond studs are exactly that. Each earring holds a single oval cut lab grown diamond of around one full carat, for a generous 2.02ct across the pair, held in a secure four claw setting in warm 18ct yellow gold. So a big, brilliant diamond sits in each ear, its elongated oval shape flattering beautifully while throwing plenty of fire. Every stone here is a lab grown diamond, a real diamond with the same sparkle as a mined one, simply made in a smarter, more affordable way. Elegant, dazzling, and endlessly wearable, these are the studs for a milestone moment, a gift to remember, or a treat you will never take off.

Why choose lab grown diamond studs? Beautiful diamonds for remarkable value. A lab grown diamond is a real diamond, grown in a controlled setting rather than mined, so it looks and lasts exactly like an earth mined stone, but costs far less. That is what makes a generous 2.02ct pair like this so affordable. The oval cut is a brilliant cut, faceted for maximum fire, and its elongated shape looks a little larger and flatters the ear. The simple four claw setting lifts each diamond to the light and shows off its full shape, while the yellow gold adds a warm, classic touch. As a result, these studs feel luxurious, versatile, and full of sparkle.

We craft these lab grown diamond studs in 18ct yellow 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 impressive size for a fraction of a mined pair.

Features:

  • Gemstone: 2 oval cut lab grown diamonds, 2.02ct total, around 1.0ct each
  • Accent Stones: None
  • Metal: 18ct yellow gold (also available in 18ct white and rose gold on request)
  • Style: Four claw oval cut solitaire studs on butterfly backs, sold as a pair

Your Lab Grown Diamond Studs 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. 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. It is what makes a generous 2.02ct 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.

How big are these studs?

They make a real statement. Each earring holds an oval cut lab grown diamond of around one full carat, so the pair totals a generous 2.02ct of diamond. That is a big, eye catching size for studs, the kind that sparkles across a room, while the oval shape keeps them elegant and flattering. 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.

Why choose an oval cut for lab grown diamond studs?

The oval is a lovely, flattering choice. It is a brilliant cut, so it sparkles intensely with fire just like a round diamond, yet its elongated shape spreads a little wider, so each stone can look larger than a round of the same weight. That gentle, elongated outline is beautifully flattering on the ear and feels a touch more distinctive than a plain round stud. On a larger pair like this, the oval shape really shows off its elegant lines. So if you want maximum sparkle, generous presence, and a shape with a little individuality, the oval cut delivers it all beautifully.

Are these studs good for everyday wear?

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 yellow 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.

How do lab grown diamonds compare on price?

This is where lab grown really shines. Because a lab grown diamond is created in a controlled setting rather than mined, it costs far less than a natural diamond of the same size and grade, often a fraction of the price. That is exactly what makes a large 2.02ct pair of studs like this so affordable, when a mined equivalent would cost many times more. So you can enjoy bigger, higher grade diamonds for your budget without compromising on beauty, since a lab grown diamond looks and lasts just like an earth mined one. So it is real luxury, made accessible.
