The Essential Jewellery Guide | Bespoke & Ethical Fine Jewellery NZ | Layla Kaisi Collection

At Layla Kaisi Collection, we understand that when it comes to fine jewellery, you want clear, concise answers to your most pressing questions. Fine jewellery is more than just adornment—it represents a story, a legacy, and a deeply personal expression. Whether you are beginning a bespoke jewellery journey or simply seeking to understand what sets authentic fine jewellery apart, this guide offers straightforward insights to help you explore the world of bespoke craftsmanship and ethical sourcing with confidence and clarity.

 

How to Identify Authentic Fine Jewellery

Authenticity is the foundation of every piece we create at Layla Kaisi Collection. Each design is handcrafted using genuine precious metals and ethically sourced precious stones. We provide certificates of authenticity (such as GIA) to verify the quality and grade of each stone.

 

Key indicators of authenticity include:

 

• Hallmarks certifying metal purity and country of origin

• Maker’s marks from reputable brands

• Impeccable craftsmanship with secure settings and hand-finished details

 

We recommend purchasing jewellery only from trusted designers who offer full transparency and documentation—like Layla Kaisi Collection.

What Is a Hallmark and Why Is It Important?

A hallmark is a small stamped symbol that guarantees the purity of your metal, usually found inside ring bands or clasps. All our 14ct and 18ct gold and platinum jewellery pieces are hallmarked according to New Zealand regulations, ensuring authenticity and quality.

Natural vs Lab-Grown Gemstones: What You Need to Know

Our collection predominantly features natural diamonds and precious stones, ethically sourced and independently certified for unmatched beauty and rarity. 

In special circumstances, and subject to the requirements of your bespoke design, we are open to sourcing lab-grown diamonds as an alternative. This option is considered on a case-by-case basis to ensure it aligns with both the design vision and our quality standards. 

To learn more about these choices and how they shape your jewellery, visit our Diamond Guide, our FAQ Page or contact us for further information.

 

Understanding the 4Cs of Diamonds

The 4Cs—Cut, Colour, Clarity, and Carat—are universal criteria for assessing diamond quality and value:

 

• Cut: Determines brilliance and sparkle

• Colour: The less colour present in a white diamond, the higher the grade

• Clarity: Measures inclusions or blemishes

• Carat: Refers to weight, and by extrapolation - size

 

Our expert team guides you through each C to select the perfect diamond for your vision.
→ Learn more about the 4 Cs in our Diamond Guide.

 

Choosing the Right Diamond Size and Carat

There is no “one size fits all” when it comes to diamond carat. It’s about finding the right balance of size, proportion, and personal significance. We help you select a diamond that complements your style and budget, ensuring a timeless, meaningful piece.

However, a good place to begin is considering the 'residence' you would like the diamond to occupy within the design and on your hand or ear or décolletage. Higher carat weight is usually equated with a larger diamond, and depending on the grade of the stone, a higher investment is required.

Current Engagement Ring Trends at LKC

While round brilliant diamonds remain a timeless choice, many clients are embracing fancy shapes such as oval, emerald, and pear; or more unique shapes such as hexagonal, lozenge, and shield shapes. There’s also growing interest in sculptural and asymmetrical settings, reflecting modern elegance with a personal twist.

Jewellery Care Tips for Longevity and Shine

To keep your jewellery radiant:

 

• Clean gently with mild soap and warm water

• Polish with a soft cloth

• Avoid exposure to chlorine, saltwater, and harsh chemicals

• Store pieces separately in soft pouches

 

For heirloom-quality pieces worn daily, professional cleaning and inspection are recommended.

Why Natural Diamonds Are So Valuable

Natural diamonds are rare geological treasures formed over billions of years. Their brilliance, durability, and symbolism make them timeless tokens of love. We source only certified natural diamonds from ethical suppliers, ensuring beauty with integrity.

For the discerning collector and investor, investing in fancy coloured diamonds is a moment of quiet opportunity. As traditional markets fluctuate and inflation shadows currency, hard luxury assets such as high-quality and rare diamonds are seeing renewed interest from wealth preservers and legacy builders. Particularly, natural fancy coloured diamonds of exceptional cut, colour and provenance are being sought not only for their brilliance, but for their incredible financial stability.

The Meaning Behind Birthstones and Anniversary Gems

Each precious stone carries unique symbolism—protection, love, strength, or prosperity. Incorporating birthstones or anniversary gems adds personal meaning and emotional resonance to your jewellery.

 

What Does Carat Measure in Gemstones?

Carat is a weight measurement (1 carat = 0.2 grams). While it influences size, a precious stone’s value also depends on cut, clarity, and colour. Our experts help you find the perfect balance for your design.

Risks of Buying Jewellery Online and How to Avoid Them

Buying jewellery online can pose risks such as treated or imitation stones, inaccurate grading, lack of certification, or poor quality craftsmanship. At Layla Kaisi Collection, all precious stones and completed designs are rigorously inspected and accompanied by authentic documentation.
