Custom jewellery, designed around this exact diamond

Design This 3.00ct Cushion Diamond Into Custom Jewellery

With actual measurements of 8.60 × 7.29 × 5.13 mm, this 3.00ct Cushion natural diamond, documented on GIA report 5473228498 can become the centrepiece of a custom engagement ring, pendant or other fine-jewellery design made around the stone’s real proportions in Melbourne.

Carat & face-up size 3.00ct

Carat is a measure of weight, while the millimetre dimensions tell you more about how large the diamond faces up and how the setting must be engineered. This stone measures 8.60 × 7.29 × 5.13 mm, so those actual dimensions can guide claw position, halo spacing, bezel size and setting clearances. At one carat or above, it can be treated as a prominent centre stone for a solitaire, halo, cathedral, three-stone or statement pendant design.

Fancy colour character Fancy Yellow

For a fancy-colour diamond, colour character and intensity are central to the face-up look. The setting can be used to harmonise with the colour or create deliberate contrast with white diamonds and different precious-metal tones. The recorded overtone is Brownish Greenish, which can also influence how the finished jewellery is styled. The actual image/video and grading report should be reviewed before making claims about the stone’s precise face-up colour.

Clarity & eye-clean review SI1

SI1 sits in the Slightly Included clarity range. Whether inclusions are visible without magnification depends on their size, relief, type and location as well as the diamond’s shape, so image/video or gemologist review is particularly useful. Ask our Graduate Gemologist (GIA) if you would like an opinion on whether this exact diamond appears eye-clean in normal viewing.

Cut, light & finish Polish EX · Symmetry GD

For a Cushion diamond, appearance should not be reduced to a Round Brilliant cut scale. Outline, facet pattern, contrast, length-to-width ratio, polish, symmetry and image/video assessment are important parts of the selection. Recorded finish: Polish EX · Symmetry GD.

From this loose diamond to finished jewellery in Melbourne

We can carry the selected stone through measurement, design and manufacture so the setting is engineered around the diamond you actually chose.

Measure the actual stone

Use the recorded 8.60 × 7.29 × 5.13 mm dimensions as the starting point for the setting rather than relying on a generic carat template.

3D / STL scan where appropriate

Where suitable for the project, precision stone measurement or 3D/STL scanning can help capture the actual outline, proportions and dimensions for custom design work.

Custom CAD design

Create CAD around the selected centre stone, including setting height, claw placement, halo spacing, side stones, band profile and wedding-band compatibility.

Design review

Review proportions, practical clearances and setting tolerances before manufacture so the finished jewellery is designed as one complete system around the stone.

Manufacture in Melbourne

Move the approved design into manufacture, stone setting, hand finishing and polishing in Melbourne, with selected projects also suitable for traditional hand-making or master-jeweller techniques.

Final inspection

Check setting security, finish and the diamond’s presentation before the completed jewellery is supplied.

Ask our Gemologist about this diamond

A grading report is an important starting point, but the actual diamond still deserves visual interpretation. Ask GemTrove's Graduate Gemologist (GIA) to help you compare the report, measurements, image/video and intended jewellery design.

  • How does the fancy colour and intensity present face-up, and which metal or halo colour would best support the look?
  • Does this particular SI1 clarity diamond appear eye-clean in normal viewing, based on the available imagery/video and report information?
  • How does the diamond’s actual sparkle, contrast and face-up pattern compare with other stones at a similar price and grade?
  • Would you like us to explain the recorded fluorescence (None) and whether it is relevant to this stone?
  • Which setting height, claw style, halo proportions and metal would best suit the actual dimensions of this diamond?

What fluorescence is recorded?
