About This Piece

Trillion Diamond celebrates the striking proportions of the trillion cut, with crisp angles and a distinctive triangular form giving the classic solitaire stud a contemporary character. Each of the 2 trillion-cut diamonds is individually secured in a refined three-prong setting, allowing its geometric silhouette to remain beautifully defined while keeping the surrounding precious metal visually minimal.

With an approx. total diamond weight of 1.30 carats across the pair, the open settings allow light to enter beneath each diamond while maintaining a clean and elegant profile. The simplicity of the design keeps the focus on the distinctive shape and brilliance of the trillion-cut diamonds.

Finished with secure post and butterfly backs and expertly crafted in Australia in your choice of premium gold or platinum, Trillion Diamond combines contemporary geometry, considered proportions and refined diamond setting in an elegant solitaire design suited to both everyday wear and special occasions.

Q: What is the difference between Lab Grown and Natural Diamonds?
A: Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are real diamonds created in highly controlled laboratory environments rather than mined from the earth.

Q: Can I change my backing style after ordering?
A: Yes, if you choose Butterfly or Screw Back and find it uncomfortable, you can return them within 30 days and we will modify the backing style for you free of charge.

Q: Are your earrings hypoallergenic and suitable for sensitive ears?
A: Yes. All our earrings are crafted from solid 10K, 14K, 18K gold or platinum with no nickel or harmful alloys, ensuring maximum comfort for daily wear.

Q: Can I customize other gemstone shapes or sizes?
A: Absolutely! We specialize in custom designs. Please click "Book A Consultation" to speak with our design team.

Choosing the right ring size is important for a comfortable and secure fit. For the most accurate result, we recommend having your finger professionally measured by a jeweller.

Measure a Ring That Already Fits

If you have a ring that fits comfortably:

Choose a ring worn on the same finger and hand as your new ring.
Measure the inside diameter of the ring from one inside edge to the other at its widest point.
Compare your measurement with the size chart below.

Ring Size Chart

AU/UK Size	US Size	Inside Diameter
H	4	14.9 mm
I	4.5	15.3 mm
J	5	15.7 mm
K	5.5	16.1 mm
L	6	16.5 mm
M	6.5	16.9 mm
N	7	17.3 mm
O	7.5	17.7 mm
P	8	18.1 mm

R	9	18.9 mm
S	9.5	19.4 mm
T	10	19.8 mm
U	10.5	20.2 mm

DOWNLOAD PRINTABLE RING SIZE GUIDE

Important: Print the guide at 100% / Actual Size. Do not select "Fit to Page" or "Scale to Fit". Check the 50 mm calibration line before measuring to ensure the guide has printed at the correct scale.

Sizing Tips

Measure the specific finger and hand where you intend to wear the ring.
Measure when your hands are at a comfortable, normal temperature.
Your fingers may change slightly in size throughout the day.
A properly fitted ring should slide over your knuckle with slight resistance and sit comfortably once in place.
Wider bands may feel more snug than narrower bands and may require a slightly different size.
