The Moissanite Edit

A 4 carat moissanite ring is a ring set with a laboratory-created moissanite stone of four carats, notable for its bold size, vivid fire, and near-colourless clarity graded to fine jewellery standards.

At Satéur, a 4 carat moissanite ring starts from around $138 — delivering the commanding presence of a stone that would cost $58,000 or more as a mined diamond for roughly 1% of the price. Every stone is graded D–E colour with an Excellent cut, reads as a near-flawless diamond to the naked eye across the table, and arrives free worldwide in the signature Satéur box with a lifetime guarantee.

Four carats is a genuinely statement weight — a moissanite engagement ring at this size reads with immediate presence in every setting. The collection spans the cuts that perform best at larger carat weights: round brilliant, oval, cushion, emerald, radiant, and marquise shapes, each amplified by halo and hidden halo frame options. Rings such as the Satéur Lumière Majesté Ring™, the elongated Satéur Lumière Ovale Ring™, and the sculpted Satéur Lumière Ciselée Ring™ show how a 4-carat moissanite stone reads across different cut profiles and gold finishes. The Satéur Star Lumière Aurous Gold Ring™ and Satéur Star Lumière Classic Silver Ring™ bring architectural star-setting detail that maximises the centre stone's vivid moissanite fire.

Moissanite returns vivid fire approximately 2.4× that of a mined diamond — a rainbow-forward dispersion visible across all lighting conditions. At 9.25 Mohs, it is extremely durable and built for continuous daily wear. All Satéur settings are finished in 18k gold — white gold for a cool, contemporary frame; yellow gold for warm editorial presence. The Satéur Renaissance d'Or Ring™ and Satéur Renaissance Éclatant Ring™ demonstrate how yellow and white gold read differently against the same 4-carat moissanite cut.

The Satéur Aurous Être Fier 1895™ Ring Bundle extends the 4-carat tier into collector territory — pairing the statement centre stone ring with a complementary band for a complete moissanite engagement bridal set. Across all settings, the diamond-grade colour and cut remains consistent: D–E colour, Excellent cut, optically stable and free of the yellowing or clouding that affects lower-quality simulants. A solitaire 4 carat ring in a classic halo or hidden halo setting is among the most searched configurations at this carat size — and Satéur's pricing makes it accessible without compromise.

Questions

4 Carat Moissanite Ring, answered.

What is a 4 carat moissanite ring?+

A 4 carat moissanite ring is a ring set with a laboratory-created moissanite centre stone of four carats weight. At this size, the stone delivers bold visual presence comparable to a mined diamond of equivalent weight, graded D–E colour with Excellent cut at Satéur, and rated 9.25 Mohs for durability.

What does a 4 carat moissanite ring cost?+

Satéur 4 carat moissanite rings start from around $138 — a fraction of the $58,000 or more that an equivalent mined diamond would command. Pricing varies by setting style (halo, hidden halo, solitaire, collector bundle) and metal choice.

How does moissanite compare to diamond in appearance?+

Moissanite returns vivid fire approximately 2.4× that of a mined diamond — a rainbow-forward sparkle visible across all lighting. It is graded D–E colour, reads as near-flawless to the naked eye, and at 4 carats makes an unmistakable visual statement.

What colour and clarity grades does Satéur's moissanite achieve?+

All Satéur moissanite is graded D–E colour (the near-colourless top range) with Excellent cut ratings, the highest tier of cut grading. This ensures consistent light return and maximum brilliance across every carat weight.

What is your return and exchange policy?+

Satéur offers free worldwide returns and exchanges. Contact customer care within the return window and we will arrange collection — no cost to you. The lifetime guarantee covers manufacturing quality.

Can I customise a 4 carat ring with a different stone shape?+
