Emerald vs Heart Cut Lab-Grown Diamonds
An emerald cut is a step cut with long, clean flashes that rewards high clarity; a heart cut is a brilliant cut built for soft, romantic light return. Choose emerald for understated, clarity-forward elegance; choose heart for a personal statement. Both are lab-grown, IGI or GIA certified, from $990 and $1190 AUD respectively at 1ct VS1.

The key difference
Because the emerald's open step facets act like a hall of mirrors, any inclusion is more visible to the naked eye, so screening for an eye-clean VS1 or better matters more here than with the heart, whose brilliant faceting helps disguise minor inclusions. The heart's value-critical points are physical rather than optical: its single point and the cleft between the lobes are vulnerable, so even lobe symmetry and a sharp, defined cleft are what to check, and the setting must protect that point.
Which should you choose?
Choose the emerald cut for understated elegance and clarity-forward beauty. Choose the heart cut for a personal, romantic statement. Both are sourced to your brief, certified by IGI or GIA, and priced AU-inclusive.
Common questions
Is an emerald or heart cut better value at 1 carat?
The emerald is the more accessible of the two, from $990 AUD at 1ct VS1, against $1190 for the heart at the same carat and clarity. The emerald's elongated step-cut outline (around 1.30 to 1.50 length-to-width) also tends to look larger face-up for the carat weight, so it offers strong visual presence for the price.
Which cut shows inclusions more, and what clarity should I choose?
The emerald shows inclusions more readily, because its step faceting creates open, mirror-like flashes that reveal flaws to the eye, so look for an eye-clean stone at VS1 or higher. The heart's brilliant faceting scatters light and helps disguise minor inclusions, though both cuts at CRTD are certified by IGI or GIA at a VS1 minimum clarity.
Are these cuts durable enough for everyday wear?
The emerald is well suited to everyday rings, with cropped, bevelled corners that are less exposed than sharp points. The heart needs more care: its single point and the cleft between the lobes are the vulnerable spots, and both depend on a careful, protective setting. With a secure setting and an even, well-defined cleft, the heart wears reliably day to day.
