The ANANTA Premium Diamond Selection
Because not all diamonds are created equal
Two diamonds with similar specifications can look entirely different on the hand of someone you love.
The 4Cs, as universally accepted as they are, have never told the whole story of a diamond. There are details only an experienced eye can see. Details that decide whether a stone feels alive or merely correct. This is why ANANTA does not stop at international standards. We set our own, stricter than the industry’s, and every diamond ring we offer passes through two rounds of selection: first by the world’s leading gemological institutes, and again by our own team of specialists.
Diamonds that meet every one of our standards we call an ANANTA Premium Diamond. Each must satisfy the following five criteria, without exception.
1. Beyond Excellent
An Excellent grade from GIA covers a wide range of cuts, which is why two diamonds with the same grade do not always shine the same. ANANTA sets its own narrower limits and measures every stone before accepting it.
The table must sit between 55 and 60 percent, the crown angle between 33.5 and 36.5 degrees, and the pavilion angle between 40.6 and 41.2 degrees. These are the proportions that let light enter, reflect within, and return to the eye at its fullest. We also decline any stone with an open culet, or a girdle cut too thin or too thick.
A diamond that passes this standard is not simply one that earned the highest grade. It is one that sits at the very top of it, and the difference is something your own eye will see.
2. Hearts and Arrows
Perfect precision leaves a signature behind, and it is shaped like a heart.
When a diamond is cut with near flawless symmetry in every facet, something remarkable appears under a special viewer: eight identical hearts arranged in a circle when seen from below, and eight arrows when seen from above. The trade has long recognised that fewer than one percent of the world’s diamonds are cut precisely enough to show it. Every round brilliant in the ANANTA Premium selection must display its hearts and arrows completely and clearly before it earns a place in our boutique.
And you never have to take our word for it. Visit us, and our team will place the stone under the scope so you can see all eight hearts with your own eyes.
3. None Fluorescence
Some diamonds look beautiful indoors, and change the moment they step outside.
Fluorescence is a reaction that causes a diamond to emit a bluish glow under ultraviolet light. In stronger cases, it can make the stone appear hazy, as though a faint film has been laid over its surface, particularly in natural daylight. It also tends to reduce long-term value in the global market. These are subtleties that never show up in a product photograph, but the person who wears the ring notices them every day.
We select only diamonds with zero fluorescence, so your engagement ring remains equally brilliant in every light — in restaurants, in sunlight, in the moments that will matter most.
4. Eye-Clean Clarity
A certificate tells you what clarity grade a diamond holds. It does not tell you where the inclusions sit.
Two diamonds at the same VVS or VS grade can look entirely different. In one, an inclusion may hide beneath the setting; in another, it may sit directly in the table, visible to the naked eye the moment the ring is on the hand. Our specialists examine every stone personally before we accept it. Only diamonds that are genuinely eye-clean, with no visible inclusions at normal viewing distance, ever make it into an ANANTA piece.
For a wedding ring you will wear every day of your life, we believe it should look flawless from every angle, in every moment, not only on paper.
5. GIA Certified & Beyond Ethical
A diamond’s credibility should never rest on the word of the person selling it, and a beautiful stone deserves a story just as beautiful.
Every ANANTA Premium Diamond comes with certification from GIA, the institute the global diamond trade has long considered the most precise and the most impartial. GIA operates as an independent third party with no stake in your decision, so every figure on the certificate is the result of scientific analysis, never of sales language. Beyond the certificate, we source only from mines and suppliers that comply with the Kimberley Process and the principles of the Responsible Jewellery Council: fully traceable, free from conflict financing, unfair labour, and environmental harm.
We believe the meaning of an engagement ring lies not only in the brilliance of the stone, but in everything it represents. An ANANTA diamond shines twice: once with its beauty, and once with the integrity its wearer can feel for a lifetime.
Because every moment deserves the very best
Choosing a diamond ring is never simply a purchase. It is the selection of something that will carry meaning for as long as two people remember why they chose it.
At ANANTA, we do not sell diamonds. We select them for the moments they will mark. Our ANANTA Premium Diamond standard is higher than the industry’s, and deliberately so, because we look after every step: the origin, the certification, the light, the clarity, and finally the hands of the craftsmen who turn the stone into a ring worthy of the person who will wear it.
For the person who will wear that diamond for a lifetime, every detail matters. That is the only reason we take care of each one.
Frequently Asked Questions
How is an ANANTA Premium Diamond different from a standard GIA-certified diamond?
A GIA-certified diamond has been graded by GIA. An ANANTA Premium Diamond passes that grading and four additional ANANTA criteria: Triple Excellent light performance, zero fluorescence, eye-clean clarity, and sourcing aligned with Responsible Jewelry Council standards. It is an additional curation layered on top of the world standard.
Why does ANANTA reject diamonds with fluorescence?
Fluorescence can cause a hazy appearance in natural light and reduce a diamond’s long-term value in the global market. We want every engagement ring to look equally brilliant in every environment, not only under showroom lighting.
How do I know a diamond is genuinely eye-clean?
Our eye-clean standard means no inclusions are visible to the naked eye at normal viewing distance (around 20-30 cm). Our specialists examine every stone in person before it is accepted. We invite clients to visit any ANANTA boutique in Bangkok to compare stones side by side.
