Loose Asscher Cut Diamonds

Asscher Cut Diamonds: Few in Number, Exact in Price

The asscher is the rarest of the ten shapes on Rare Carat: 33,578 stones today (every carat weight), 8,987 natural and 24,591 lab grown, against 181,545 for its close cousin the emerald cut. It is a square step cut with cropped corners whose concentric facets form the windmill pattern you see looking straight down into the table, and it rewards exactly the qualities that make a diamond expensive: high clarity, high color and precise symmetry. Natural asschers start at $270 and lab asschers at $130 with the current savings applied; in the one carat band the medians are $2,046 natural and $643 lab. Figures come from inventory on October 17, 2026 and are refreshed regularly.

Two cautions before the tables. An asscher carries weight in its depth, so it faces up smaller than any other shape at the same carat, about 5.5 mm square at one carat against 6.5 mm for a round. And its open step facets show inclusions and color the way an emerald cut does, so the cheapest grades that pass in a round or a radiant do not pass here.

Clarity and Color: Why an Asscher Buyer Pays for Both

With color held at G to H in one carat natural asschers, SI2 starts at $855, SI1 at $845, VS2 at $925, VS1 at $1,055 and VVS2 at $1,065. Our gemologists set the floor at VS1 for a natural asscher and VS2 only when the video shows the inclusion in a corner, because the windmill pattern draws the eye straight to the center of the table. Color behaves the same way: holding clarity at VS2, D starts at $1,235, G at $1,065, H at $925 and I at $870, and the warmth of an I asscher is visible in white metal. Lab asschers make both decisions cheap: 3,544 of the 3,581 one carat lab asschers on the color ladder are D to F, and VS1 among D to F lab stones starts at $490, VVS2 at $540.

Natural Asscher Prices by Carat

Because so few natural asschers exist, a single stone can move a band's median, and the counts below are the honest guide to what you can actually choose from: 2,335 natural asschers between 0.90 and 1.10 carats, 496 between 1.90 and 2.10, 115 between 2.90 and 3.10. Medians run $2,046, $9,820 and $27,290. Per carat, a natural asscher is priced close to a natural emerald cut of the same grade and below a round, because the square step cut keeps more of the rough.

Lab Grown Asscher Prices by Carat

Lab grown asschers are 24,591 of the stones on this page, and they turn the shape's main weakness, the small face up size, into a non issue: a two carat lab asscher, about 7 mm square, has a median of $1,703, and a three carat one, about 8.2 mm, $2,887. The one carat median is $643 and the deepest band is 1.50 to 1.89 ct.

Square or Slightly Rectangular

A true asscher is square, with a ratio between 1.00 and 1.04; stones above 1.05 begin to read as short emerald cuts. 8,842 of the natural asschers here are square and 145 are slightly rectangular; in lab grown the split is 24,148 square to 443 rectangular. The square ones are what most buyers mean by asscher, and the windmill pattern only forms properly when the outline is square and the corners are cut to the same width, so check the symmetry of the pattern on the 360 HD video rather than relying on the ratio alone.

The Same Asscher, Mined or Grown

A one carat G color VS1 asscher starts at $1,215 natural (median $2,007) and $465 lab; E color VVS2 is $1,360 natural against $540 lab. 8,761 of the natural asschers are GIA graded and 6,783 have no fluorescence; lab asschers are graded mostly by IGI (23,600 of 24,591). For the weight most people buy, see 1 carat asscher cut diamonds and 1 carat asscher cut lab grown diamonds; for the shape's nearest relative, the emerald cut diamonds page uses the same basis.
