Some people want the stone that came out of the ground, and the argument for it is not financial; it is that it did. We source each natural diamond against its GIA report at H colour, VS clarity and excellent cut, polish and symmetry, which is the grade where a mined stone is white and clean to the eye. You see the report before it is set.

The ladder starts at half a carat and runs to one, deliberately. Under a carat is where a natural diamond is still priced sanely; above it the price climbs steeply for a difference in diameter of a millimetre or two. If size matters more than origin, the lab grown ladder gives you two carats for less than a mined one.

About natural diamond rings

How can I tell a natural diamond from a lab grown one?
You cannot by eye, and neither can a jeweller without laboratory equipment. The GIA report states the origin and the stone carries a laser inscription on its girdle matching the report number.
What grade are the natural stones?
H colour, VS1 or VS2 clarity, excellent cut, polish and symmetry, GIA certified. White and clean to the eye without paying for grades that only show under magnification.
Are your natural diamonds conflict free?
They are sourced through a trade marketplace whose suppliers warrant Kimberley Process compliance, and the GIA report travels with the stone. We state that plainly rather than making a broader claim we cannot verify.
