Heart natural diamonds
A heart cut is a brilliant cut in a heart outline, best from about one carat up. Natural stones are rarer and hold more of their value as a traditional heirloom choice.

Questions buyers ask
Are lab-grown diamonds real diamonds?
Yes. A lab-grown diamond is pure crystallised carbon with the same hardness, refractive index and chemical structure as a mined diamond. Gem labs such as IGI and GIA grade them with the same colour, clarity and cut scales, and the report states that the stone is laboratory-grown.
How much cheaper is lab-grown than natural?
For the same size and quality, a lab-grown diamond usually costs a small fraction of a natural one. On our current price list a 1 carat round F-G VS lab-grown diamond is £320 and a comparable GIA-graded natural diamond is £3,900.
Which certificate comes with my diamond?
Lab-grown centre stones and loose stones come with an IGI report. Natural diamonds of 0.30 ct and above come with a GIA report. The report number is laser-inscribed on the girdle, and we send you the report before we charge.
