Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 0.33 carat white sapphire in a princess cut, colorless and untreated, documented on AGCL Report #M263120. Princess-cut white sapphire at 0.33 carats is a small, geometric accent stone — the square outline with sharp corners creates a modern, architectural look distinct from round or cushion alternatives at this scale. White (colorless) sapphire at Mohs 9 is the hardest colorless gemstone other than diamond, making it the most durable diamond substitute available at any size.
Expert Opinion
Ahmed Shareek's Assessment
"This princess-cut white sapphire has genuinely sharp, symmetrical corners rather than the softened 'squarish' outline I see on a lot of budget princess cuts — combined with AGCL-confirmed unheated colorless corundum at Mohs 9, it's a diamond alternative I'd recommend without hesitation for a modern accent setting."
Rarity Analysis
A few factors make this stone less common than typical white sapphire supply:
-
Color: True colorless corundum is uncommon — most "white" sapphire on the market carries a faint gray, yellow, or blue cast, and this stone is graded fully colorless.
-
Size: At 0.33 ct, this is an accent-scale stone; well-proportioned princess cuts at this weight are less common than round or oval equivalents.
-
Treatment: Unheated, per AGCL Report #M263120 — most colorless corundum entering the market has been treated to remove residual body color.
-
Cut: Princess cutting sacrifices more rough weight than round or oval cuts to achieve sharp corners, making a well-executed princess-cut sapphire less common at this size.
-
Documentation: Independently verified on AGCL Report #M263120, confirming species, weight, dimensions, and treatment status.
-
Combined effect: Natural colorlessness, unheated status, and precise princess geometry at a small accent scale together make this a genuinely uncommon stone relative to typical white sapphire supply.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
Verify colorlessness in person if possible. "White" sapphire can carry undertones that only show under certain lighting; request additional photos or video in daylight-equivalent light if you're buying sight unseen.
-
Confirm your setting protects the corners. Princess cuts have exposed corners that are more vulnerable to chipping than rounded cuts — a setting with corner-protecting prongs is recommended for daily wear.
-
Consider the accent-stone scale. At 0.33 ct, this stone is sized for accents, small pendants, or stacking rings rather than a large center-stone statement.
-
Check the clarity grade against your use case. Very Slightly Included is a realistic, honestly disclosed grade for a natural stone — review the included photos and video closely if flawless clarity matters to you.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
