The Best Shapes for Champagne Diamonds

In this guide

    By Clint Casmiro, Co-Founder, Smiro Studio, Toronto · Updated September 28, 2026

    Short answer: Our most popular champagne diamond shapes are the classics: ovals, cushions and radiants. Old mine cuts get a lot of attention online, but ovals are what sell for us right now. Brilliant shapes like these spread the warm colour evenly with sparkle. Step cuts like emeralds show the colour more strongly and evenly, with less sparkle.

    These are the shapes people actually buy in champagne, and why.

    Our most popular shapes we get for champagne diamonds are the classics, ovals, cushions, radiants. People are always seeing the old mine cuts for champagne, but the most classic shapes like ovals are what are the hot sellers for us right now.

    Oval

    Our best seller. Long, flattering on the finger, and the brilliant faceting keeps the warm colour lively. Look for a well cut oval so there is no dark bowtie, which can look muddier in a champagne stone.

    Cushion

    Soft corners and a vintage feel that suits warm colour. Crushed ice cushions glitter; chunkier facets give bigger flashes of colour.

    Radiant

    Straight sides, clipped corners and a busy sparkle. A radiant can make a champagne stone read a little lighter because the facets scatter light.

    Old mine and step cuts

    Old mine cuts have big, slow flashes and look antique, which is why they are all over social media. Step cuts like emerald show body colour most strongly, so they suit people who want the colour front and centre.

    One of one

    Every champagne stone we list is a single stone. When it sells, it is gone, and the next one will be a slightly different colour. Shop what we have now.
