Round, Marquise & Emerald-Cut Diamond Three-Stone Cluster 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.

While our prices may appear lower than most jewellers, the quality behind each piece speaks otherwise. In fact, our production costs are often higher — because we insist on doing things the right way:

• Every piece undergoes multiple rounds of quality control
• We use thicker bands, meaning more gold and longer-lasting wear
• Only top-grade gemstones make the cut for our collection

By keeping our margins low and prioritising craftsmanship over markups, we’re able to offer exceptional jewellery — at a price that’s genuinely fair.

All our lab-grown diamonds over 0.5ct and gemstones over 2.0ct come with a dedicated IGI report. For designs set with three or more gemstones and a total carat weight of 2 carats or above, we provide an IGI jewellery report instead.

While most UK jewellery brands only provide IGI certificates for lab-grown diamonds, we ensure that the lab-grown gemstones we use are also accompanied by a dedicated IGI report.  So you’ll always have peace of mind that every stone originates from a place we’ve personally chosen for its ethical practices.

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