Asscher cut sapphires combine a square outline with deep stepped facets and large cropped corners, producing the distinctive hall-of-mirrors reflection of an emerald cut in a balanced square format. The cut was developed for diamond in 1902 and has since become a defining shape of art deco design - geometric, symmetrical, and unmistakably elegant. For the rectangular step-cut equivalent, see our emerald cut sapphire collection. For square brilliant-faceted alternatives, see our square sapphire collection.
Looking for an Asscher Cut Sapphire?
We do not currently have Asscher cut sapphires in stock - they are one of the rarest shapes in natural sapphire because they require exceptional rough with very high clarity (the step facets reveal every inclusion) and a near-perfect square crystal structure to cut economically. We cut Asschers on commission when we have the right rough available. Email crescentgems@gmail.com with your preferred colour, carat weight, and budget and we will source and cut to specification. Most commissions can be completed in 4-8 weeks through our Sri Lanka cutting workshop.
Why the Asscher Cut Is So Rare in Sapphire
The Asscher requires square rough - sapphire crystals tend to form as hexagonal barrels or flat tablets, making perfectly square rough uncommon. The step facets demand eye-clean material; any significant inclusion in the table is immediately visible. And the deep pavilion consumes significant rough weight. The combination of these factors makes fine Asscher cut blue, teal, and purple sapphires genuinely uncommon. For the closest available alternative in stock, see our emerald cut collection and our square sapphire collection. For all step-cut formats, see our rectangular sapphire collection. For why Ceylon origin matters for a commissioned stone, see our Ceylon sapphire origin guide.
