9ct Yellow Gold 2.4ct Lab-Grown Diamond Mixed-Shape Bezel-Set Stud Earrings

A stud earring is the simplest structure in jewellery and the least forgiving: a setting, a post and a back, with nothing to hide behind.

This one is 9ct yellow gold, carrying 2.4 ct of lab-grown diamonds in total, in a mixed-shape line. As a shape, a mixed-shape line alternates cuts along its length, so no two adjacent stones throw light the same way.

Will this suit me?

• Size: Sold as a pair, with 2.4 ct of diamonds in total across a mix of shapes: about 1.2 ct per earring.
• Comfort and security: The smooth bezel collar has nothing to catch on clothing or hair. At this weight, a larger disc back helps the earrings sit upright on softer lobes.
• Everyday wear: Earrings take very little wear, and 9ct is the harder alloy, so these will stand up to being worn every day.
• Other options: Metal: 9ct white gold.

A bezel setting wraps a continuous collar of gold around the girdle of the stone. It is the most protective setting there is: nothing catches, nothing snags, and the stone cannot be knocked loose from the side. The trade-off is that the collar covers a little of the stone's edge, so a bezel-set stone reads marginally smaller than a claw-set one of the same weight.

What matters is that the setting sits flat to the lobe and the post is centred in it. An off-centre post is the reason studs tilt forward as the day goes on.

9ct yellow gold is 375 parts per thousand fine gold. The higher alloy content makes it hard and more scratch-resistant than 18ct, which is why it's always been the popular choice for everyday wear.

Care. Sold as a pair. Butterfly backs loosen with wear and are worth replacing before they are lost.
