a natural emerald
origin: Zambia

💧 Minor oiling
Almost all emeralds on the market are oiled to improve their transparency. Oiling graded as minor corresponds to a very limited intervention, a traditional practice accepted in the emerald trade — an uncommon level of treatment, which reinforces the stone's value.
💎 Significance and positioning
Zambian emeralds are renowned for their deep, slightly bluish green and their fine crystallinity. With a weight of 3.58 carats, a colour certified vivid green and minor oiling attested by the laboratory, this stone ticks the boxes sought after on the market. The elongated cushion cut (10.08 × 8.03 mm) offers fine face-up presence while preserving the depth of the colour.
💍 Use in jewellery
This emerald is suited to:
a centre-stone ring
a high-jewellery pendant
a unique, bespoke piece
Settings in yellow gold, white gold or platinum are traditionally favoured to enhance the green hue while offering adequate protection to this gem, which is naturally sensitive to knocks.
