The Gemstone Guide: Natural Stones Behind iBrilliance shop Jewellery (1)
Share
At iBrilliance shop, every piece of jewellery begins with a stone. Not a manufactured imitation, not a synthetic replica — but a genuine natural gemstone, formed over thousands or millions of years beneath the earth's surface, or cultivated in the quiet depths of freshwater rivers and lakes.
This guide introduces you to the natural materials at the heart of our collections: what they are, where they come from, what makes each one unique, and how to care for them. Whether you are a first-time buyer or a seasoned jewellery lover, understanding your stones will deepen your appreciation of every piece you wear.
1. Natural Turquoise — The Sky Stone
Few gemstones carry the cultural weight of turquoise. Prized for over 5,000 years by ancient Egyptians, Persians, Native Americans, and Tibetan monks, turquoise is one of the oldest gemstones in human history. Its vivid sky-blue colour — ranging from pale robin's egg to deep teal — has made it a symbol of protection, wisdom, and good fortune across civilisations.
What is natural turquoise?
Turquoise is a hydrated phosphate mineral of copper and aluminium, formed when water percolates through copper-rich rock over millions of years. The copper content gives it its characteristic blue colour; iron traces introduce green tones. The dark veining you see in turquoise — known as the matrix — is the surrounding host rock, and is a hallmark of authenticity. No two pieces of natural turquoise are identical.
How to identify genuine turquoise
The market is flooded with dyed howlite, plastic, and resin imitations sold as turquoise. Genuine natural turquoise has:
- Subtle, irregular matrix veining (not perfectly uniform)
- Slight variations in colour tone across the surface
- A cool, slightly waxy feel
- Natural weight — heavier than plastic, lighter than glass
All turquoise used in iBrilliance shop jewellery is genuine natural turquoise, sourced for its vivid colour and authentic matrix character.
Turquoise care
Turquoise is a porous stone — it can absorb oils, perfumes, and liquids, which may alter its colour over time. Keep it dry, away from lotions and chemicals, and wipe gently with a soft dry cloth after wearing. Never use ultrasonic cleaners or steam on turquoise.

2. Freshwater Baroque Pearl — Nature's Sculpture
Pearls are the only gemstone created by a living creature. While perfectly round cultured pearls dominate the mainstream market, baroque pearls — irregular, free-form, and gloriously unique — are experiencing a renaissance among jewellery lovers who value character over conformity.
What is a baroque pearl?
A baroque pearl forms when an irritant enters a freshwater mussel and the creature coats it in layers of nacre (the iridescent substance that gives pearls their lustre). Unlike round pearls, which are formed around perfectly spherical nuclei, baroque pearls grow freely — resulting in organic, sculptural shapes: elongated drops, wings, coins, and abstract forms that no two pieces share.
What makes freshwater baroque pearls special?
- Iridescent lustre: The soft, glowing sheen of nacre — creamy white with pink, silver, or gold overtones — is impossible to replicate synthetically.
- Unique silhouette: Every baroque pearl is a one-of-a-kind sculpture. The piece you wear exists nowhere else in the world.
- Organic authenticity: Slight irregularities in shape, surface, and colour are not flaws — they are proof of natural origin.
Pearl care
Pearls are organic and relatively soft (Mohs hardness 2.5–4.5). They are the last thing you put on and the first thing you take off. Wipe with a soft damp cloth after wearing. Avoid perfumes, hairsprays, and acids. Store flat in a soft pouch — never hang pearl necklaces, as the thread can stretch.

3. Natural Pink Raw Stone — Unpolished Romance
Raw stones — gemstones in their natural, unpolished state — have surged in popularity as buyers seek jewellery that feels authentic, earthy, and connected to the natural world. Our natural pink raw stone beads are sourced for their soft blush-to-coral gradient, each one a unique expression of colour and texture.
What is pink raw stone?
Pink raw stone refers to natural mineral beads that have been minimally processed — tumbled smooth but not faceted or highly polished — preserving the stone's natural surface character. The pink tones come from mineral inclusions within the stone matrix. Common pink gemstones in this category include rose quartz, rhodonite, and pink calcite, each with its own subtle colour signature.
Why raw stones?
The appeal of raw stone jewellery lies in its honesty. Each bead carries the marks of its geological journey — slight variations in colour, texture, and shape that make every necklace a unique object. No two strands are identical, and that is precisely the point.
Raw stone care
Avoid prolonged contact with water and chemicals. Wipe with a soft dry cloth. Store separately to prevent scratching against harder stones or metal components.

4. Natural Green Stone — The Colour of Growth
Green has long been associated with nature, renewal, and balance. Our natural green stone pieces — from deep forest-green spacer beads to rich teardrop pendants — bring an earthy, grounding energy to jewellery design.
What is natural green stone?
Green gemstones encompass a wide family of minerals, including aventurine, malachite, green agate, and jade. Each has its own colour depth, surface character, and mineral composition. What unites them is their natural origin and the rich, complex greens that no synthetic material can fully replicate.
- Green aventurine: A quartz variety with a sparkling, glittery effect caused by reflective mineral inclusions (known as aventurescence). Soft sage to medium green.
- Malachite: A vivid, banded green copper carbonate mineral with distinctive swirling patterns. Deep, saturated green.
- Green agate: A translucent to opaque chalcedony with smooth, even colour. Versatile and durable.
Green stone care
Most green stones are moderately hard and durable. Avoid harsh chemicals and prolonged water exposure. Wipe clean with a soft dry cloth and store in a soft pouch.

A Note on Natural Variation
Every natural gemstone used in iBrilliance shop jewellery is unique. Colour, tone, matrix pattern, surface texture, and size will vary between individual pieces — sometimes subtly, sometimes significantly. This is not a defect. It is the defining characteristic of natural materials, and the reason no two pieces from our collections are ever truly identical.
When you purchase a piece from iBrilliance shop, you are not buying a mass-produced object. You are acquiring a piece of the natural world, shaped by geological time and human craft into something you can wear every day.
