The 1.5 Carat Edit

A 1.5 carat lab grown diamond ring centres on a real, lab-created diamond weighing one and a half carats, grown in a controlled laboratory environment rather than mined from the earth.

The Satéur Aurous Gold Destinée Diamond Ring™ opens this edit: a 1.5 carat presence built on a real, IGI-certified lab-grown diamond for a fraction of the mined price. Every ring in the collection arrives with complimentary delivery, a lifetime guarantee, and the signature Satéur box — a complete proposal moment, not just a stone in a sleeve. The size reads instantly on the hand, yet the value reads quietly on the receipt.

Each setting is crafted in solid 18K gold, the same precious metal used in the finest fine jewellery, and every centre diamond is independently certified by IGI. Solid gold means the ring holds its weight, its colour, and its integrity for a lifetime of daily wear — no plating, no compromise, no shortcuts in the metal that frames the stone.

The centre is a real diamond in every measurable sense. Lab-grown diamonds share the same crystal structure and the same Mohs 10 hardness as mined diamonds, and the stones in this edit are selected in the D–E colour range with Excellent cut grades and VS clarity. That combination delivers the bright, near-colourless brilliance and the clean light return you expect from a premium engagement diamond.

This 1.5 carat lab grown diamond ring collection spans the classic round brilliant, the elongating oval, and the soft-shouldered elongated cushion, each set in solid 18K white or yellow gold. Carat weight stays consistent at the one-and-a-half-carat mark while the cut, the colour, and the clarity define the character of each diamond engagement ring. Round, ideal-cut, and fancy-shaped lab grown diamonds appear across the range, every piece priced against the value of a comparable mined stone. The grid below shows every piece.

Questions

1.5 Carat Lab Grown Diamond Ring, answered.

What is a 1.5 carat lab grown diamond ring?+

It is a ring set with a real, lab-created diamond weighing one and a half carats. The diamond is grown in a controlled laboratory under conditions that replicate how diamonds form in nature, producing a genuine diamond with the same crystal structure and Mohs 10 hardness as a mined stone — at a fraction of the mined-diamond price.

What is carat weight and how does it affect diamond price?+

Carat is the unit that measures a diamond's weight, with one carat equal to 0.2 grams. Larger carat weights are rarer and so command higher prices per carat, which is why a 1.5 carat stone costs disproportionately more than a 1 carat. Lab grown diamonds let you reach that 1.5 carat size for a fraction of what a comparable mined diamond would cost.

What colour grade is most common for 1.5 carat lab diamonds?+

The diamonds in this edit are selected in the D–E colour range — the top, near-colourless end of the grading scale. At this grade the stone faces up bright and white with no visible tint, which gives a 1.5 carat diamond the clean, icy presence most people picture in an engagement ring.

What clarity grade should I choose for a 1.5 carat engagement ring?+

We select VS clarity for this collection, meaning any inclusions are very slight and not visible to the naked eye. VS offers an excellent balance for a 1.5 carat engagement ring: the diamond looks clean and brilliant in everyday wear without paying a premium for a grade you cannot see without magnification.

How does a 1.5 carat lab diamond compare in size to a mined diamond of the same weight?+

Identical. A 1.5 carat lab grown diamond and a 1.5 carat mined diamond have the same weight and the same physical dimensions, so they appear exactly the same size on the hand. The difference is in origin and price, not in how the stone looks on the finger.

Are lab-grown diamonds certified by independent gemological labs?+

Yes. Every centre diamond in this collection is independently certified by IGI, one of the world's recognised gemological laboratories. The certificate documents the carat weight, colour, cut, and clarity of the stone, giving you the same verified grading you would expect from any premium diamond.
