9ct Yellow Gold 1.7ct Lab-Grown Diamond Emerald-Cut 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 1.7 ct of lab-grown diamonds in total, cut emerald-cut. As a shape, an emerald cut is a step cut: broad parallel facets and a flat table, which trades sparkle for clarity and a long, architectural flash.

Will this suit me?

• Size: Sold as a pair. Each earring carries about 0.85 ct; an emerald cut of that weight typically measures about 6.5 × 4.5 mm face-up (for scale, an Australian 5c coin is 19.4 mm across).
• On the ear: Noticeable without being oversized: an easy everyday size. Emerald cut stones look a little larger than a round stone of the same weight. Their broad, flat facets give long flashes of light rather than sparkle.
• Comfort and security: The smooth bezel collar has nothing to catch on clothing or hair.
• 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. Total weight: 2 ct.

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.
