6 Carat Lab Grown Round Cut Diamonds

Many proportionally balanced 6 carat lab grown round cut diamonds measure around 11.7–11.8mm across, but individual stones should always be checked separately.

These measurements reveal how the stone carries its weight. Two 6ct lab grown round cut diamonds can have noticeably different visible spreads despite similar carat figures.

The report provides essential measurements and grades, but available imagery can add useful context about inclusion visibility and the appearance of the individual stone.

It can. A larger diameter and deeper profile can influence how high the centre stone sits, so setting height should be considered alongside security and overall ring proportions.

Platinum is generally preferred at this scale for its strength and durability, offering better long term security for a large centre stone than gold, particularly in claw settings carrying significant weight.

We recommend speaking with a specialist jewellery insurer given the value involved. We provide a full valuation certificate with every purchase to support this process.

Yes, this is exactly what the consultation process is for. We discuss your priorities and either source from available stock or arrange sourcing to match your specification as closely as possible.

Full IGI or GIA certification is standard, documenting cut, colour, clarity, carat, and additional measurements including symmetry, polish and fluorescence. We are happy to talk you through every detail.

Yes, though given the individual sourcing process at this weight, we would recommend booking a consultation first so we can prepare relevant stones for you to view.
