FAQs
What's the difference between 3EX and Hearts & Arrows?
3EX is triple-Excellent — the baseline for a fine round. Hearts & Arrows is a superideal tier above it, cut precisely enough to show eight arrows and hearts under a dedicated viewer. Every H&A is 3EX; most 3EX isn't H&A.
Does Excellent guarantee the best light performance?
No — it's a reliable filter, not a finish line. Excellent covers a range of proportions, and where a stone sits within that range determines its real performance.
What loose parcels do you supply?
The full range — sieve sizes through melee, pointers from 18 to 99 points, and certified or non-certified parcels at a carat and up, across FL-I1 and D-Z.
What are TTLB shade Diamonds?
Near-white naturals with a faint warm shade that often face up white, especially in yellow gold, priced well below equivalent white stones — strong value for the right setting.
Can Raremonds supply matched pairs and calibrated layouts?
Yes. We expertly match diamonds for diameter, colour, brilliance, fluorescence, and face-up appearance to create perfectly balanced pairs and jewellery layouts.

READ MORE
Round Brilliant diamonds remain the world’s most popular and recognisable diamond shape. Known for delivering exceptional brilliance, fire, and scintillation, they continue to set the benchmark for engagement rings and fine jewellery. While the rise of lab-grown diamonds has transformed the commercial market, premium natural Round Brilliant diamonds continue to hold strong value, particularly in larger sizes and exceptional makes. Today, selecting the right round diamond depends on far more than its certificate—it requires expert evaluation of cut performance, proportions, and overall beauty.
Why Round Brilliant Diamonds Remain the Industry Standard
The Round Brilliant cut is engineered to maximise light performance, making it the preferred choice for solitaire rings, bridal jewellery, and luxury collections. As the most widely graded diamond shape, it also offers excellent market liquidity and pricing transparency. Whether sourcing a single centre stone or calibrated parcels, consistent quality and expert selection remain essential.
Understanding Cut Quality and Hearts & Arrows
Every premium round diamond should begin with Triple Excellent (3EX) grading for cut, polish, and symmetry. However, not all Excellent diamonds perform equally. Hearts & Arrows diamonds represent an even higher level of cutting precision, displaying perfectly aligned optical symmetry that enhances brilliance and fire. At Raremonds, we evaluate every diamond beyond its grading report by assessing proportions, fluorescence, polish quality, and real-world light performance.
Certified Stones, Matched Pairs & Loose Parcels
Raremonds supplies GIA-certified Round Brilliant diamonds across every size, colour, and clarity for engagement rings and bespoke jewellery. We also provide expertly matched pairs for earrings and calibrated parcels for pavé, halos, tennis bracelets, and eternity bands. Every parcel is matched for face-up diameter, colour consistency, fluorescence, and overall appearance to ensure seamless layouts and exceptional craftsmanship.
Loose Diamonds for Every Jewellery Requirement
Our inventory includes the complete range of loose natural Round Brilliant diamonds, from melee and calibrated sieve goods to pointers, one-carat stones, and larger certified diamonds.
