The parcel

A selected parcel of polished blue turquoise cabochons. The lot covers two visible families: near-solid bright blue stones with little or no matrix, and heavily webbed stones with pronounced dark spiderweb patterning. Shown hand-held outdoors and in close-up so the matrix structure and polish can be judged directly.

Material

Polished turquoise cabochons, blue tones ranging from near-solid bright blue to strong dark spiderweb matrix.

Condition

Surfaces are polished and free of obvious chips in the frames shown. Matrix contrast varies stone by stone. No photographic retouching has been applied; colours are as captured.

Sampling

Partial quantities are drawn at random from the parcel. A sample is representative of the colour and matrix mix in general terms, but no two draws are identical and stone-to-stone variation within the parcel is high.

Included

Loose polished cabochons in the mix shown.

Not included

Cord, setting, certificate, gift packaging and duties are not included unless stated on the quotation.
