5 results · $18 to $120
Apatite
Colour and appearance across the available views.

Colour and cut in the actual lot photographs.
4 results · $61 to $202
Tourmaline
How colour appears across the stone and between views.

Sapphire
Colour alongside size. Compare saturation, tone, cut and the stated measurements for the individual stone.
87 results · $6 to $432
Ruby
The colour in different photographs, read alongside the stated identity. A photograph alone does not verify a mineral identification.

21 results · $6 to $121
Citrine
Saturation and tone. Compare the colour you see across the lot's photographs.
20 results · $4 to $97
Topaz
Whether irradiation, heat or another treatment is disclosed, and what supporting information is supplied.
26 results · $21 to $166
Garnet
Which garnet variety is stated. Similar appearances in a small photograph do not verify the variety.
34 results · $9 to $104
Emerald
Colour alongside clarity, cut, measurements and condition. Read these details together for the individual stone.
23 results · $8 to $484
Peridot
How little brown is in the green, which is the whole of the colour grading here.
20 results · $13 to $86
Diopside
Weight against tone. Under two carats is usually where the colour still reads green.
7 results · $4 to $61
Fluorite
Colour banding, which is a feature of the species rather than a defect.
21 results · $3 to $99
Opal
Whether it is a solid stone, a doublet or a triplet.
75 results · $2 to $140
Diamond
Whether the lot is described as natural or lab-grown, and what supporting information is supplied.
108 results · $9 to $530
