Oval Cut Diamond Halo Stud Earrings

All Keanis diamonds are selected to meet the highest standards across the 4Cs — Colour, Clarity, Cut and Carat — the globally recognised benchmarks of diamond quality.

Colour
The diamond colour scale ranges from D (completely colourless) to Z (light yellow or brown). At Keanis, we offer only the top two grades — D (the highest) and E (second highest). Both are classified as colourless, delivering exceptional brilliance, purity, and timeless appeal.

Clarity
Our diamonds are available in IF (Internally Flawless), VVS (Very Very Slightly Included), and VS (Very Slightly Included) grades — with the majority being eye-clean, meaning no inclusions are visible without magnification.

Cut
While Cut options aren’t listed, we only use the highest grade for each diamond:

• Ideal Cut (maximum fire and brilliance — applicable to round cuts only)
• Excellent Symmetry
• Excellent Polish
  

Accent Diamonds
All of our accent stones are full-cut (57–58 facets for round shapes), offering maximum sparkle. We use only D–E colour and VVS–VS clarity — the same standards found in high-end fine jewellery.

We believe fine jewellery should reflect the quality of its materials, craftsmanship and design. Our approach to pricing is straightforward: we focus on what goes into each piece and carefully manage our costs to offer considered value.

• Every piece undergoes multiple rounds of quality control
• Our designs are made with considered proportions and substantial precious metal weight
• Gemstones are carefully selected to meet our quality standards
• We work closely with our manufacturing partners to maintain consistency in craftsmanship and finishing

By focusing our resources on the jewellery itself, we’re able to create beautifully made pieces at thoughtfully considered prices.

To ensure absolute transparency, our qualifying lab-grown diamonds and gemstones are accompanied by a dedicated IGI report, depending on their individual specifications.

We choose to go beyond standard market practice that limits independent certification to diamonds alone by extending this rigorous assurance to our exceptional gemstones as well. This guarantees you complete peace of mind that each significant stone meets our exacting criteria for ethical origin and technical excellence.

You can learn more in our Gemstone & Jewellery Certification Guide.
