A loose lab-grown pink sapphire, oval 6 x 8 mm, about 1.8 carats, faceted in the Faelight™ Cut, Aquamarise’s concave fantasy cut. The color is a soft, even blush pink that holds in daylight and under warm bulbs. This is the exact stone in the photo and video, unset and ready to set.

The Faelight Cut
The Faelight Cut carves radiating curved grooves into the underside of the stone instead of flat facets. Light reflecting off those curves breaks into fine rays, so the stone reads as a starburst from across a room and as bright lines up close. The pattern is cut into the stone and does not wear off. More on the family in our guide to fantasy-inspired engagement rings.
The Lab-Grown Pink Sapphire
Lab-grown sapphire is real corundum, the same crystal as mined sapphire, with the same Mohs 9 hardness and the same optics; it is grown rather than mined, which is why it is this clean and evenly colored. Sapphire is the September birthstone; our sapphire meaning guide has the background.
This Stone
The outline is a oval: the classic rounded outline, the easiest shape to set. It measures 6 x 8 mm, about 1.8 carats by the cutter’s figure; the millimeters are what a setting is built to.
Same stone, other outlines: kite 7 x 10 mm, kite 6 x 9 mm, long hexagon 5 x 9 mm, long hexagon 6 x 10 mm, marquise 5 x 10 mm, coffin 6 x 10 mm, rectangle 6 x 8 mm, pear 6 x 8 mm.
Same oval 6 x 8 mm in other stones: blue sapphire, green sapphire, lavender sapphire, sky blue topaz, ametrine.
Setting It
Leave the back open: prongs, an open-backed bezel or a cathedral with an open gallery keep the starburst alive, while a closed back dims it. Aquamarise can set this stone into a design built around it; start at custom engagement rings or read how to build a custom engagement ring. The rest of our unset stones are in loose gemstones.

Care
Warm water, mild dish soap and a soft brush worked into the grooves on the underside, then rinse and dry on a lint-free cloth. Sapphire will not scratch in ordinary wear but will scratch softer stones, so store it on its own. Our guide to cleaning jewelry at home covers the routine.
Frequently Asked Questions
What is the Faelight Cut?
A concave fantasy cut. The underside of the stone is carved with radiating curved grooves instead of flat facets, so light reflects off the curves and breaks into fine starburst rays. The pattern is cut into the stone and does not wear off.
Is this a real sapphire?
Yes. It is lab-grown sapphire, which is genuine corundum with the same chemical composition, hardness and optical properties as mined sapphire. The difference is where the crystal formed, in a growth chamber rather than in the ground, and that is why it is clean and evenly colored.
Is the photo the stone I will receive?
Yes. This listing is one individual stone, photographed and filmed on its own. If it sells and is cut again, the replacement is the same size and color but a different stone.
What happens if it shows as sold out?
It can usually be cut again to order in the same size and color; allow roughly three to five weeks. Contact us before ordering if timing matters.
Can Aquamarise set this stone into a ring or pendant?
Yes. Contact us with the setting you have in mind; we build the design around the stone's exact dimensions. Open-backed settings suit this cut best because the starburst lives in the pavilion.
Does it come with a certificate?
No. No independent laboratory report is included. The stone type, origin, dimensions and approximate carat weight are stated on this page; an independent appraisal can be arranged after purchase.
How durable is it for daily wear?
Sapphire is corundum at 9 on the Mohs scale, harder than every common gemstone except diamond and moissanite, and suited to a ring worn every day.
