The Colour House

Begin with Colour

Every piece begins with one stone, chosen for what it is rather than what it fills. Start wherever you like — we will build the rest around it.

950 Stones held
16 Species

Section One

Gemstone Type

Every species held in the house. If you already know the name, begin here.

01

Ruby

Pigeon Blood · Rose Red

Pigeon Blood describes a specific saturation, not a flourish. Most rubies on the market are treated to improve clarity — ours state it in the title, because the price already reflects it.

Ruby
02

Sapphire

Royal Blue · Cornflower · Padparadscha · Yellow

Royal Blue and Cornflower are confirmed trade names on the report, not adjectives we chose. Where a stone is unheated, the certificate says so before we do.

Sapphire
03

Emerald

Vivid Green · Cabochon · Carved

Graded on the openness of its green more than the absence of inclusions. We keep cabochons and carved pieces alongside faceted stones, because not every emerald wants to be a solitaire.

Emerald
04

Paraiba

Neon Blue · AIGS recorded

The colour comes from copper inside the crystal, which is why nothing else looks quite like it under any light. Under a carat, in the right colour, it is one of the few honest ways into the material.

05

Chrysoberyl

Cat’s eye · Honey

A single band of light across the dome, sharpest when the stone is cut for the eye and nothing else. Orientation matters more than weight.

Rubellite

Red tourmaline

Tourmaline in its deepest red, held to a stricter colour standard than pink. The name is earned on the report, not assumed.

Aquamarine

Santa Maria · March birthstone

Santa Maria is a colour grade named for the Brazilian mine where it was first found — it describes a specific vivid blue, and stones from Mozambique can carry it too.

Kunzite

Pink-purple · Large cuts

Found in sizes other pink stones rarely reach, and best kept out of long direct sun so the colour holds.

Morganite

Peach beryl

Beryl in peach — the same family as emerald and aquamarine, at its softest. Photography for this species is being reshot.

Tourmaline

Pink · Green · Bi-colour

One species covering more of the spectrum than any other, which is why it appears twice in this list. October birthstone.

Tourmaline

Spinel

Purplish · Grey · Red

Mistaken for ruby for centuries, and now collected on its own terms. Rarely treated, and often the most honest stone in a parcel.

Tanzanite

Blue-purple · Single source

Found in one place on earth, in a strip of ground a few kilometres wide. It shifts between blue and violet depending on the angle you hold it, which is the whole reason to own one.

Garnet

Spessartine · Tsavorite · Rhodolite

The family that spans the widest range of colour we hold — Namibian Fanta orange at one end, Tanzanian tsavorite green at the other, and no treatment on either.

Topaz

Blue · Golden · White

A December stone, wide in size and colour, and honest about which pieces have been treated to reach their blue.

Topaz

Imperial Topaz

Golden · Champagne · Brazil

The only topaz that carries the name. Brazilian, and graded on warmth rather than clarity alone.

Opal

Ethiopian · White · Pink · Fire

Colour that moves rather than sits. Held faceted, as cabochon, and carved — the only stone here judged on what it does when you tilt it.

Section Four

Birthstones

The oldest reason to choose a stone, and still the most personal. Twelve months, each with its own colour and its own long history.

Garnet
Garnet spans far more colour than its reputation suggests — Namibian orange spessartine at one end, Tanzanian tsavorite green at the other. Carried for centuries as a travelling stone, given for safe return.
Signs Capricorn · Aquarius
February

Amethyst
Quartz at its most saturated purple. Worn by bishops, and before them by anyone who wanted a clear head — the name comes from the Greek for “not intoxicated”.
Signs Aquarius · Pisces
March

Aquamarine
Beryl in cool, open blue. Sailors carried it as a calm-water stone. Today the grading argument is entirely about how much of that blue survives when you look straight down into it.
Signs Pisces · Aries
April

Diamond
The hardest natural material, and the only birthstone that arrives colourless as standard. We hold fancy colours alongside white — boron makes blue, nitrogen makes yellow.
Signs Aries · Taurus
May

Emerald
Green beryl, and the one stone where inclusions are expected rather than penalised. Cleopatra’s mines ran for centuries before a Colombian emerald was ever cut.
Signs Taurus · Gemini
June

Alexandrite · Pearl
The only month whose stone changes colour by light source — green by day, red by lamp. Pearl shares the month, and is the only organic gem on this list.
Signs Gemini · Cancer

Ruby
Corundum in red — the same mineral as sapphire, separated only by chromium. Pigeon Blood is the grade everyone reaches for and few stones actually earn.
Signs Cancer · Leo
August

August
Peridot · Spinel
Peridot arrives from volcanic rock and, occasionally, from meteorites. Spinel joined the month recently, after centuries of being sold as ruby by mistake.
Signs Leo · Virgo

Sapphire
Blue is the expectation, but sapphire runs yellow, pink, green and padparadscha too. Where a stone is unheated the report states it, and the price follows.
Signs Virgo · Libra

Opal · Tourmaline
Two stones judged by movement rather than stillness — opal for the colour that travels across it, tourmaline for the way a single crystal can hold two colours at once.
Signs Libra · Scorpio
November

Citrine · Golden Topaz
The warm month. Imperial topaz from Brazil carries the finest of it, graded on the depth of its gold rather than on clarity alone.
Signs Scorpio · Sagittarius
December

December
Tanzanite · Zircon · Blue Topaz
Tanzanite was found in 1967 and comes from one place only. Zircon is among the oldest minerals on earth. The month holds both the newest gem and the oldest.

Every Stone, On the Record

Laboratory, colour grade and treatment status appear before the price does. Where a stone has been treated, we say so in the title — because the price already reflects it.

Sourcing

Not here? We will find it.

What is listed on this site is a fraction of what we can reach. Roughly one stone in ten ever makes it onto these pages — the rest sit uncut, unphotographed, or still with the dealers and cutters we buy from.

So if the colour, size or cut you have in mind is not here, that almost never means it does not exist. Describe it, and we will go and look.

01Tell us the stone, the colour, and roughly the size
02We search our own vault, our cutters, and the dealers we buy from
03You see photographs, certificates and prices before anything is committed

Every field takes your own words. If the stone you want is not on any list, type it — a name we do not show is not a name we cannot find.

Replies come from sales@saratti.com, usually within one working day.

And then

Two Ways Forward

Once a stone has your attention, there are only two questions left.

Take the stone

As It Is

Held loose, certified, and shipped insured. Yours to set later, or to keep exactly as it left the cutter.

Build around it

Made to Answer the Stone

A setting designed for this stone and no other. Six weeks at the bench, reviewed with you before anything is cut.
