UNDERSTANDING DIAMONDS

Diamonds have long been admired for their brilliance, rarity, symbolism, and enduring beauty. Whether chosen to celebrate a milestone, mark a commitment, or become part of an heirloom collection, they remain one of the most meaningful gemstones in fine jewelry


Today, shoppers have more choices than ever before. Alongside natural diamonds formed deep within the earth over billions of years, technological innovation has introduced environmentally conscious lab grown diamonds: real diamonds created above ground with the same physical, chemical, and optical properties — offering a modern alternative within fine jewelry.

WHAT MAKES A DIAMOND VALUABLE?

Diamonds are traditionally evaluated using the internationally recognized 4Cs.

CUT

The way a diamond interacts with light, creating brilliance, fire, and sparkle.

CLARITY

The natural internal characteristics formed during growth.

COLOR

The absence of visible color within a diamond.

CARAT

The diamond’s weight, not necessarily how large it appears visually.

NATURAL DIAMONDS

Natural diamonds are formed beneath the Earth’s surface over billions of years through intense heat and pressure. Each diamond forms uniquely in nature, making every stone one of a kind.


Many buyers value natural diamonds for their rarity, geological origin, and long-standing connection to heirloom jewelry and traditional luxury.

LAB GROWN DIAMONDS

Lab grown diamonds are created using advanced technology that replicates the natural diamond-growing process in a controlled environment.

They share the same:

  • Chemical composition
  • Crystal structure
  • Brilliance
  • Hardness
  • Optical properties

as natural diamonds

Many buyers appreciate lab grown diamonds for their modern innovation, design flexibility, and accessibility to larger sizes and higher qualities.

NATURAL VS. LAB GROWN

Both natural and lab-grown diamonds are real diamonds. The primary difference is how they are formed.

NATURAL DIAMONDS LAB GROWN DIAMONDS
Formed within the Earth Created in laboratories
Billions of years old Grown over weeks or months
Geological rarity Technological innovation
Traditional luxury heritage Modern fine jewelry approach

Neither option is inherently better — the right choice depends on personal preference, priorities, and what matters most to you.

CERTIFICATION & TRANSPARENCY

Diamond grading reports provide an independent assessment of a diamond’s quality and characteristics, helping buyers shop with greater confidence and transparency.


Reports may include:

  • 4Cs grading
  • Measurements and proportions
  • Polish and symmetry
  • Fluorescence
  • Inclusion mapping
  • Laser inscription details

We recommend purchasing certified diamonds whenever possible.

CHOOSING THE RIGHT DIAMOND

Selecting a diamond is personal. Some buyers prioritize natural rarity and tradition, while others value innovation, size, or flexibility in design.


The most meaningful diamond is ultimately the one that feels right to you.

OUR PHILOSOPHY

We believe modern fine jewelry should offer informed choice, transparency, and exceptional craftsmanship.

How to Measure Your Finger

Method 1 — String or Measuring Tape

  1. Wrap a flexible measuring tape or strip of paper/string around the finger where the ring will be worn.
  2. Ensure the fit is snug but comfortable
  3. Mark where the ends meet.
  4. Measure the length in millimetres.
  5. Match the measurement to the circumference column in the chart above.

Measure an Existing Ring

A useful method when measuring for yourself or as a surprise:

  1. Choose a ring that fits the intended finger.
  2. Measure the inside diameter of the ring in millimetres.
  3. Match the diameter to the chart above to determine size.

Sizing Tips for the Best Fit

  • Fingers naturally change size throughout the day — measure at the end of the day when fingers are largest.
  • Avoid measuring when hands are cold or swollen.
  • Rings should slide on easily but resist slightly over the knuckle.
  • Wider bands fit more snugly — consider sizing up 0.25–0.5 size.
  • If between sizes, choose the larger size.
