There's something about diamonds that make a holiday extra memorable—they're sparkling, luxurious and unexpected. As one of the leading fine-jewelry brands selling lab-grown diamonds, Ada's sustainably cultured diamonds are true diamonds, with the exact same crystal structure, chemical composition, optical and physical properties as mined diamonds. Grown by recreating the conditions underneath the Earth that result in a diamond (pressure, heat and carbon), they're judged on the same merits of cut, color, clarity and carat. But grown diamonds are more environmentally friendly and conflict-free. Even better, because they sell for 30-40% less than mined diamonds of comparable size and quality, you can buy a bigger, better quality diamond for your budget. Herewith, some suggestions on what to give in your price range.
