Marcus Tempus
The Sophia is a beautifully simple diamond solitaire, designed with clean lines and classic proportions that place all the attention on the centre stone.
Crafted in Platinum 950, the ring is set with a 0.24ct natural round brilliant diamond, selected in E colour and VS2 clarity and accompanied by its individual GIA certificate. Four polished claws secure the diamond while leaving it open to the light, allowing its natural brilliance to remain the defining feature of the design.
The gently tapered platinum band gives Sophia a refined, delicate appearance on the hand without distracting from the diamond. It's a traditional engagement ring in the best sense — uncomplicated, beautifully made and designed to remain relevant long after trends have changed.
Part of The House of Gemstones collection, where exceptional gemstones meet timeless craftsmanship.

The House of Gemstones
Natural diamonds are among the most extraordinary materials found on Earth. Their hardness, brilliance and optical performance have made them enduring symbols of rarity, permanence and commitment.
Every natural diamond has its own balance of colour, clarity, cut and internal characteristics, giving each stone an individual identity.
Nature’s Architecture
Natural diamond commonly forms in octahedral and related cubic crystal habits.Diamonds are exceptionally resistant to scratching, but they are not indestructible. A sharp impact in the wrong direction can chip or cleave a diamond.
Understanding Diamond Quality
Cut quality influences brilliance, fire, scintillation and how effectively light returns to the eye.
For colourless to near-colourless diamonds, grading commonly runs from D through Z.
Clarity considers internal inclusions and external characteristics under controlled magnification.
Carat measures weight, not visual size. Equal carat weights can look very different.
Colourless to Near-Colourless
Natural diamonds in the colourless-to-light range are commonly graded from D to Z. D represents the absence of detectable body colour at the top of the scale, while later letters show progressively more noticeable yellow or brown tone.
A lower colour grade does not automatically mean an unattractive diamond. Metal colour, setting style, cut quality and personal preference all influence how a stone appears when worn.
Natural Characteristics
Flawless or internally flawless under standard grading conditions.
Very, very slight inclusions that are extremely difficult to see under magnification.
Very slight inclusions that remain relatively difficult to observe under magnification.
Slight inclusions that are easier to locate and may sometimes be visible without magnification.
Included diamonds show more obvious clarity characteristics that may affect transparency or durability.
A Natural Fingerprint
Natural diamonds may contain crystals, feathers, clouds, needles, pinpoints or other internal features created during or after formation.
These characteristics can help identify a stone and tell part of its geological story. Their position, size, number and nature influence the clarity grade.
Light Performance
Cut quality describes much more than a diamond's outline shape. Proportions, symmetry and polish determine how effectively light enters, reflects and returns to the eye.
The return of white light.
The separation of white light into spectral colours.
Flashes of light and dark seen as the diamond or observer moves.
Cut Is Not the Same as Shape
Under Ultraviolet Light
Some natural diamonds emit visible light when exposed to ultraviolet radiation. Blue is the most commonly observed fluorescence colour.
Fluorescence is not automatically positive or negative. Its influence depends on the individual diamond and should be considered alongside colour, transparency and overall appearance.
Transparency Matters
Natural diamonds can occasionally receive treatments intended to alter colour or clarity. Where a treatment is known or identified, it should be clearly disclosed. At Marcus Tempus, we favour natural diamonds in their untreated state and source from trusted suppliers, while assessing stones and supporting documentation individually.
May be used to reach and reduce the visibility of certain dark inclusions.
May reduce the visibility of surface-reaching fractures and requires disclosure.
High pressure and high temperature treatment can alter the colour of some natural diamonds.
Can be used to modify diamond colour and should always be disclosed.
Independent Assessment
A grading report records gemmological observations such as carat weight, measurements, colour, clarity and, where applicable, cut quality and fluorescence. Depending on the diamond, an independent grading report may accompany the stone.
GIA
IGI
HRD Antwerp
Recognised independent gemmological laboratories include GIA, IGI and HRD Antwerp. Natural diamonds may be accompanied by an independent grading report from one of these or another recognised laboratory. The laboratory and type of report will vary depending on the individual diamond; the logos shown here do not imply that every Marcus Tempus diamond is graded by these laboratories.
Responsible Sourcing
We favour trusted suppliers and transparent sourcing wherever possible. Natural diamond provenance can vary according to size, age, market route and documentation, so we assess each stone and piece individually.
Marcus Tempus Diamond Selection
We select natural diamonds for beauty first, considering cut quality, brightness, colour, clarity, proportions and overall character. Where a grading report is supplied, we use it as part of the assessment rather than as a substitute for looking at the stone itself.
Marcus Tempus Bespoke
Natural diamond jewellery can be created around your preferred shape, carat weight, colour, clarity, precious metal and overall budget. We can help balance the 4Cs so the finished piece prioritises the qualities that matter most to you.
Natural diamond availability varies by shape, carat weight, colour, clarity, cut and certification. Some combinations may require sourcing time or small design adjustments.

A natural diamond is formed within the Earth through geological processes rather than grown in a laboratory.
Diamond ranks 10 on the Mohs scale and is exceptionally scratch resistant, although it can still chip or cleave.
There is no single answer, but cut quality often has the greatest influence on brilliance and visual performance.
No. Appearance depends on the individual stone, setting, metal colour and personal preference.
No. Fluorescence is not automatically negative and should be judged in context.
No. A grading report describes gemstone characteristics; a valuation assesses the finished item's value for a stated purpose.
