Short answer: sapphire is corundum, and it comes in almost every colour except red, which is called ruby; non-blue sapphires are known in the trade as fancy sapphires. The most prized is padparadscha, a delicate blend of pink and orange named after the Sinhalese word for the lotus blossom and traditionally associated with Sri Lanka. Pink, yellow, orange, purple, green, white, colour-change and multi-coloured "parti" sapphires share blue sapphire's hardness of 9, which makes them among the best coloured stones for everyday rings, but treatments vary widely and matter greatly to value.

Ask most people to picture a sapphire and they see blue. Gemmologically, blue is just one colour of corundum, coloured by iron and titanium. Change the trace elements and the same mineral turns pink, yellow, orange, violet, green or colourless, and every one of those stones is a sapphire with the same durability.

Fancy sapphires are having a long moment as engagement and dress ring stones, and for good reason. But they are also where some of the trade's most important treatment stories sit, including the beryllium diffusion episode of the early 2000s, which still shapes how orange and padparadscha-coloured stones are tested today. Here is what each colour is, where it comes from, how it is usually treated and what drives value.

What is a fancy sapphire?

A fancy sapphire is any gem-quality corundum that is not blue and not red. Red corundum is ruby; blue is sapphire; every other colour is sold as a sapphire with a colour name, such as pink sapphire, yellow sapphire or green sapphire.

The boundary between pink sapphire and ruby is not fixed. Strongly saturated pinkish-red stones may be called ruby by one laboratory or market and pink sapphire by another, and the name can make a significant difference to price. If a stone sits near that line, the name on a reputable lab report is the one that counts.

Which sapphire colours exist, and how are they usually treated?

Fancy sapphires come in a wide range of colours, and each colour tends to have its own typical sources and treatments. The table below is a general guide; individual stones vary, and only testing tells you what has been done to a specific one.

Heat treatment of corundum is long established, stable and accepted when disclosed. Diffusion, filling and irradiation are different matters. Our guide to common gemstone treatments explains each.

What is a padparadscha sapphire?

A padparadscha is a sapphire of a delicate, balanced pinkish-orange to orangish-pink colour, usually light to medium in tone. The name comes from the Sinhalese word for the colour of the lotus blossom, and Sri Lanka is the classic source.

Padparadscha is defined by colour, and that is its difficulty. Too much pink and it becomes a pink sapphire; too much orange and it becomes an orange sapphire; too dark or too brown and it falls outside the term altogether. Major laboratories have worked towards shared criteria, but their exact boundaries still differ, so one stone can be called padparadscha by one lab and a pink-orange sapphire by another. Madagascar and Tanzania have also produced stones within the range, and the name is generally applied by colour rather than by origin.

There is one more subtlety. Some pinkish-orange sapphires owe part of their colour to an unstable cause that can fade with exposure to light, and laboratories may test for this. A padparadscha report from a respected lab, stating colour, treatment and, where possible, origin, is the minimum for a significant stone.

What was the beryllium diffusion scandal?

In the early 2000s, large quantities of orange, yellow and padparadscha-like sapphires reached the market whose colour had been created by heating them with beryllium, which diffuses into the crystal and changes its colour. At first the treatment was not disclosed, and it was not readily detected by standard tests.

Gemmological laboratories identified the cause using advanced chemical analysis, and the trade moved to disclosure. The lasting effects are practical. Orange and padparadscha-coloured sapphires, in particular, now need testing by a laboratory with the right instruments, and beryllium-diffused stones are worth far less than heated-only or unheated stones of similar appearance. The episode is a good reason never to buy an important fancy sapphire without a current report.

What are parti sapphires and Montana sapphires?

Parti sapphires show two or more distinct colours in one stone, most often blue, green and yellow, in zones that a cutter can arrange to striking effect. They come mainly from Australia, Montana, Madagascar and parts of Africa, and are often untreated.

Montana sapphires, mined in the United States since the late nineteenth century, are known for steely blues, teals, greens and pastel colours, often in modest sizes. Much Montana material is heat treated, though unheated stones are available. Both have become popular with buyers who want a sapphire that does not look like anyone else's.

What drives the value of a fancy sapphire?

Colour drives value above everything: the most desirable hue for that colour family, strong saturation and a tone that is neither washed out nor too dark. After colour come treatment, size, clarity, cut and documented origin.

1. Colour. A vivid, even colour without greyness or brown is worth far more than a pale or muddy one.
2. Treatment. Unheated stones command a premium, especially in padparadscha, pink and yellow. Diffusion and filling reduce value sharply.
3. Size. Fine fancy sapphires become scarce above a few carats, and price rises steeply with size.
4. Clarity. Eye-clean stones are preferred; silk and fine inclusions are normal and can identify natural origin.
5. Cut. A well-cut stone shows even colour without a dead window in the centre.
6. Origin and documentation. Origin matters most for padparadscha; a respected lab report underpins value for any important stone.

Our guide to what makes a gemstone fine covers the principles shared by all coloured stones.

Are fancy sapphires good for engagement rings?

Yes. Every sapphire, whatever its colour, is 9 on the Mohs scale and very tough, which makes fancy sapphires among the most practical coloured stones for a ring worn every day. Only diamond is harder among the stones you are likely to consider.

The exception is a stone whose fractures have been filled with glass or resin, which is less durable and needs gentle cleaning; a lab report will say. Our Mohs hardness guide compares sapphire with the alternatives. A pink or padparadscha sapphire also pairs beautifully with a diamond in a two-stone design; our guide to the toi et moi ring shows how.

What are the alternatives to fancy sapphires?

Pink and orange spinel is the closest alternative: hard, often untreated and frequently brighter than sapphire of similar price. If you want neon blue-green rather than pink or orange, Paraiba tourmaline is a different and rarer proposition. Our guides to spinel and Paraiba tourmaline set out their strengths.

Do fancy sapphires appear in antique jewelry?

Yes, though blue sapphires dominate antique jewelry by a wide margin. Yellow, pink and white sapphires appear in Victorian, Edwardian and Art Deco pieces, and white sapphires were sometimes used as diamond substitutes. Old stones are usually unheated or heated by simpler means than today's.

Our antique sapphires guide covers the period cuts, settings and sources. For a sense of blue sapphire in a nineteenth-century setting, our Imperial Russian three-sapphire ring of 1864 is a good counterpoint to the fancy colours here.

Questions people actually ask

What is a padparadscha sapphire?

A padparadscha is a sapphire with a delicate, balanced pinkish-orange to orangish-pink colour, usually light to medium in tone. The name comes from the Sinhalese word for the colour of the lotus blossom, and Sri Lanka is the classic source, though Madagascar and Tanzania produce stones too. Laboratories differ slightly in where they draw the colour boundaries.

Is a pink sapphire the same as a ruby?

Both are corundum, but they are named differently by colour. Red corundum is ruby; pink corundum is pink sapphire. The boundary between strongly coloured pink sapphire and lighter ruby is not universally fixed and can differ between laboratories and markets. Because the name can affect price significantly, rely on a reputable lab report for stones near that line.

Are fancy sapphires treated?

Many are. Heat treatment is common for pink, yellow, padparadscha and white sapphires, and is stable and accepted when disclosed. Some orange, yellow and padparadscha-coloured stones have been diffused with beryllium, which must be disclosed and reduces value. Green, purple, colour-change and parti sapphires are often unheated. A lab report confirms what has been done.

Why are padparadscha sapphires so expensive?

Because fine padparadscha is rare. The colour must sit within a narrow pink-orange band, in a light to medium tone, and few stones achieve it with good clarity and size. Unheated stones with a respected lab report and Sri Lankan origin command the highest prices. Lookalike colours created by beryllium diffusion are worth far less.

What is a parti sapphire?

A parti sapphire shows two or more distinct colours in a single stone, usually zones of blue, green and yellow. They come mainly from Australia, Montana, Madagascar and parts of Africa, and are often untreated. Each one is different, which appeals to buyers looking for an individual stone rather than a uniform, catalogue colour.

Are yellow sapphires durable for everyday wear?

Yes. Yellow sapphire is corundum, 9 on the Mohs scale and very tough, so it suits an everyday ring as well as blue sapphire does. Clean it with warm water, mild soap and a soft brush. Take more care only if a lab report shows fracture filling, which is less durable than the stone itself.

What was the beryllium diffusion scandal?

In the early 2000s, many orange, yellow and padparadscha-like sapphires reached the market with colour created by heating them with beryllium, initially without disclosure. Laboratories identified the treatment using advanced chemical analysis, and the trade moved to disclosure. As a result, orange and padparadscha-coloured sapphires now need testing by a well-equipped lab.
