• Emerald: a rectangular step cut with a hall-of-mirrors look that requires high clarity.
• F colour: colourless, with a slight tint detectable only by experts under controlled light.
• VS1 clarity: very slight inclusions, eye-clean to virtually everyone.
• Lab-grown: chemically identical to natural diamonds, typically at least 90% less than a comparable natural cohort from 1 carat up.
