Custom jewellery, designed around this exact diamond

Design This 1.50ct Round Diamond Into Custom Jewellery

With actual measurements of 7.09 × 7.18 × 4.60 mm, this 1.50ct Round natural diamond, documented on GIA report 6421379369 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 1.50ct

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 7.09 × 7.18 × 4.60 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.

Colour character N

N sits in the N–R very-light colour range and can show a distinctly warmer character than colourless or near-colourless diamonds. That warmth can be made part of the design through metal, halo and side-stone choices rather than treated simply as a grade to hide.

Clarity & eye-clean review SI2

SI2 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 Very Good

The recorded Round Brilliant cut grade is Very Good. Cut has a major influence on brightness, fire, scintillation and the pattern of light and dark seen face-up. Recorded finish: Polish EX · Symmetry VG.

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 7.09 × 7.18 × 4.60 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 warm does this exact N colour diamond look in the current image/video, and how might yellow gold, rose gold or platinum change the presentation?
  • Does this particular SI2 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?

Frequently asked questions

Answers are generated from the approved catalogue fields for this exact diamond and do not replace the laboratory report.
Is this a natural or lab-grown diamond?
This is a natural diamond. The origin type is taken from the approved GemTrove catalogue record and should be read together with the laboratory grading report.
What are the main characteristics of this diamond?
This diamond is a 1.50 carat Round with N colour and SI2 clarity. These values come from the current approved catalogue record.
How should I understand the colour grade?
The recorded colour is N. Face-up appearance can vary with lighting, surrounding metal colour, cut proportions and the observer, so the grading report and an in-person or video review remain important.
What does the SI2 clarity grade mean for this diamond?
SI2 is the clarity grade recorded for this diamond. The location, type and visibility of inclusions can differ between diamonds with the same grade, so the grading report and magnified media should be reviewed.
What finish grades are recorded?
The recorded finish grades are VG cut, EX polish, VG symmetry. Cut, polish and symmetry describe different aspects of proportion, surface finish and facet alignment.
What proportions are available for this diamond?
The available proportion data records table 55.0%, depth 64.5%, crown angle 38.00°, pavilion angle 40.00°, length-to-width ratio 0.99. Proportions should be considered together rather than using one number alone to judge appearance.
What are the physical measurements?
The recorded measurements are 7.09 × 7.18 × 4.60 mm. Measurements help assess face-up spread and are also important when confirming a suitable setting.
Does this diamond have a grading report?
Yes. The catalogue record identifies grading report GIA 6421379369. The report number should be checked against the laboratory record before purchase or setting.
What fluorescence is recorded?
The recorded fluorescence grade is NON. Fluorescence describes the response under ultraviolet light and does not by itself describe ordinary viewing appearance.
How is the displayed price calculated?
The displayed price is converted at runtime from the approved USD source price into the selected display currency. The public price is shown as tax-inclusive and rounded according to GemTrove pricing rules.
