Anne Hathaway’s Oscars Necklace: What Defines High Jewellery?
What is high jewellery?
High jewellery refers to the most exceptional level of fine jewellery, where rare diamonds, advanced craftsmanship, and precise design come together to create one-of-a-kind pieces. These designs are defined not just by carat weight, but by how each stone is selected, cut, and set to maximise light performance and overall balance.
At the 2026 Oscars, Anne Hathaway showcased this perfectly in a statement piece by Bvlgari.

Anne Hathaway’s Oscars Necklace: A Closer Look
At the centre of the necklace sits an 8.02 carat pear-cut Fancy Vivid Yellow diamond, known for its rare and even colour distribution.
The piece features over 35 carats of diamonds, combining pear, round, and step cuts to create movement and maximise light reflection.
A detachable pendant adds versatility — a signature detail often seen in high jewellery design.
The Craftsmanship Behind High Jewellery
This necklace required over 850 hours to create, reflecting the level of precision involved in high jewellery.
At this level:
-
Diamonds are selected individually for light performance
-
Settings are engineered for maximum brilliance
-
Every element is balanced to ensure harmony and movement
High jewellery is not defined by size alone — but by how every detail works together.
What Defines High Jewellery vs Fine Jewellery
| Feature | High Jewellery | Standard Fine Jewellery |
|---|---|---|
| Diamond Selection | Individually selected for light performance | Selected primarily by specs |
| Craftsmanship | Hundreds of hours | Standard production |
| Design | One-of-a-kind or limited | Repeatable designs |
| Light Performance | Optimised at every angle | Varies significantly |
Why Diamond Selection Matters More Than Carat Weight
Two diamonds can have the same certificate and carat weight — yet look completely different in real life.
This is because:
-
Cut quality affects brilliance
-
Proportions affect light return
-
Setting affects how the diamond performs
We recommend prioritising light performance and balance over carat weight alone, particularly for elongated shapes such as oval, pear, and marquise.
What This Means for Diamond Buyers in Australia
For buyers in Australia and Sydney, access to diamonds often relies heavily on certification data and online listings.
However, certificates do not show:
-
light performance
-
bow tie strength
-
real-life brilliance
This is why careful evaluation and a trusted jeweller is essential when selecting a diamond.
Applying High Jewellery Principles at Carat House
At Carat House, we apply the same principles seen in high jewellery when selecting diamonds.
Each stone is assessed not just on certification, but on:
-
how it reflects light
-
its overall balance
-
how it will appear once set
This ensures every piece maintains a refined, high-end finish.

FAQ
What is high jewellery?
High jewellery refers to one-of-a-kind or extremely high-end pieces featuring rare diamonds, intricate craftsmanship, and exceptional design.
Why is light performance important in diamonds?
Light performance determines how much a diamond sparkles. A well-cut diamond reflects light more effectively, making it appear brighter and more valuable.
Do bigger diamonds always look better?
No. A smaller diamond with excellent cut and light performance can appear more brilliant than a larger, poorly cut stone.
