Cosmic Galaxy Natural Opal Necklace

An opal contains multitudes. Green, black, blue, gold — sometimes all at once, depending on the angle and the light. No two opals have ever displayed colour in exactly the same way. The Cosmic Galaxy Natural Opal Necklace was named for what the stone already is.

The Cosmic Galaxy Natural Opal Necklace by Zanvari features a certified natural opal — 1 to 1.5 carats, pear shape — with cubic zirconia accents, set in 925 sterling silver on an 18-inch chain. The opal's play-of-colour makes this the most unique necklace in Zanvari's collection. No two pieces are identical because no two opals are identical. Rs. 18,900. Made to order in Karachi by Zanvari, third generation jewellers since 1947.

Natural opal — the stone that contains all colours

Opal is the only gemstone whose defining quality is a play of colours — the shifting rainbow-like display that moves through the stone as it is turned. This optical phenomenon occurs because opal is made of hydrated silica spheres: when light strikes them, it diffracts into the visible spectrum, producing flashes of green, blue, gold, and red that appear and disappear depending on viewing angle. The dominant colours in the Cosmic Galaxy pendant are lush greens and deep blacks — the characteristic combination of high-quality opal that makes each flash appear more vivid against the dark background. Natural opal at this quality level is genuinely rare: no two stones have ever displayed colour in exactly the same way.

Important — natural stone variation

Because this pendant uses a genuine natural opal, the exact colour display, pattern, and tone of your piece will differ from the product photographs. This is not a flaw — it is the defining characteristic of natural opal. The stone you receive will have its own unique play-of-colour, formed over millions of years. Zanvari selects each opal for quality and colour intensity, but the specific pattern will be yours alone.

Care instructions

Opal requires specific care. Store in the Zanvari box away from direct sunlight — opal contains water in its structure and can crack if it dries too quickly. Do not store in airtight containers for extended periods. Apply perfume before putting the necklace on. Avoid ultrasonic cleaners, steam, and harsh chemicals. Wipe with a soft damp cloth. Opal at 5.5–6.5 Mohs is softer than most other gemstones — handle with care. Lifetime replating guarantee at no charge.

Frequently asked questions

Is this a natural opal?

Yes — certified natural opal. The certificate confirms the stone's natural origin and distinguishes it from synthetic opal, doublets, or triplets (assembled stones). Contact 0342 8269771 on WhatsApp to discuss certification before ordering.

Will my pendant look exactly like the product photograph?

No — and this is intentional. Natural opal's play-of-colour varies from stone to stone. The dominant colours will be similar, but the exact pattern and distribution of your stone will be unique. This is the nature of natural opal.
