Teardrop Cut Amethyst: lighter in weight than diamond, with more fire than a round here

Brilliance 49 · Fire 60 · Scintillation 81 · in our census, where the T73 scores 72 · 36 · 80 in amethyst

A softened pear in quartz: more fire than the T73, less light, and one of the least steady faces we measure when it tips.

Teardrop Cut Amethyst

The teardrop is a pear with a fuller shoulder and a gentler point. Ours runs 1.445 times longer than it is wide, on 74 facets, and its 38.46° pavilion gives a stone 60.0% deep.

Its fire, 60, is well above the T73's 36 in amethyst. We still list fire as a con, because each score counts once, against the baseline it differs from more, and the diamond teardrop scores 89.

The pavilion is under the 40.4° guide minimum for rounds. We have no measurements of a steeper teardrop, so this page reports the cut as drawn.

Does a teardrop suit amethyst? Pros and cons

Compared with the T73 Round Brilliant in amethyst and with the Teardrop Cut in diamond. A difference counts from 3 points (Brilliance, Fire, Tilt, Leakage), 5 (Scintillation, Symmetry), 2 (Spread) or 5% (weight); Tilt counts as a pro only for a stone within 5 points of the brilliance it is compared with. How we measure.

What amethyst gains in a teardrop

A quarter lighter than diamond

0.96 ct at 6.5 mm, against 1.28 ct for the same cut in diamond (−25%)

A teardrop 6.5 mm across the shoulder weighs 0.96 ct in amethyst; the diamond version is 1.28 ct.

The catch with a teardrop amethyst

Less fire than the diamond teardrop

Fire 60 against 89 for the Teardrop Cut in diamond: 29 points lower

Quartz splits white light into colour less than a third as strongly as diamond. Against the round in amethyst the teardrop does well; against its own shape in diamond it cannot.

Teardrop Cut in diamond · Fire 89

Look at the coloured flashes: those are fire. Same light, same size, same face-up angle; rendered by our 3D Gemstone Simulator from each cut's own model.

What helps: Shorten the outline: the Oval Cut Amethyst reaches 69, top of our amethyst list.

Loses light when tipped

Tilt 56 against 80 for the T73 Round Brilliant in amethyst: 24 points lower

Tipped by 20°, the teardrop keeps 56 of its face-up light; the T73 keeps 80. Only one cut we measure in amethyst does worse.

Tilt is how much of its own face-up light a stone keeps when tilted. Each frame is the Light Return map with the stone tilted away from you by the angle shown; grey is light leaving through the pavilion. The share under each frame is that picture's own.

What helps: The Oval Cut Amethyst holds 74 when tipped, steadier than the pear or the marquise in quartz.

Less light than the T73

Brilliance 49 against 72 for the T73 Round Brilliant in amethyst: 23 points lower

Part of the elongated face does not send light back, and in pear-like shapes that loss often gathers as a darker band across the widest part.

T73 Round Brilliant in amethyst · Brilliance 72

Red, green and blue = light returning to the eye; grey = light leaving through the pavilion. This is the head-on view; the Brilliance score averages a wider cone of light, so the score can differ from what one picture shows.

What helps: The Pear Cut Amethyst returns 52, the Oval Cut Amethyst 52.

Leakage 41 against 28 for the T73 Round Brilliant in amethyst: 13 points higher

41% of the light in our census leaves through the pavilion, against 28% for the round in amethyst.

Who a teardrop amethyst suits

The teardrop suits amethyst pendants and earrings where a soft point is wanted and some colour play is welcome. In a drop that swings, its low Tilt score is worth weighing.

Against the classic Pear Cut Amethyst it is very close: a little less light, the same fire, and a more regular pavilion.

If the drop should hold its light as it moves and show more colour, the Oval Cut Amethyst does both.
