Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.06 carat white sapphire in a radiant cut, colorless and untreated. White (colorless) sapphire is corundum without the trace elements that produce color — the same mineral as blue or yellow sapphire, but entirely without chromophores. At Mohs 9, it is substantially harder than any other colorless gemstone alternative to diamond. The radiant cut combines the architectural outline of a rectangular shape with brilliant faceting, producing strong light return in the colorless material.
Expert Opinion
Ahmed Shareek's Assessment
"This 1.06 ct radiant-cut white sapphire is untreated, eye-clean, and cut with a rectangular, brilliant-faceted outline that gives colorless corundum a modern silhouette with strong light return."
Rarity Analysis
Colorless (white) sapphire is a minority outcome of overall corundum production, since most rough carries at least trace color.
-
Color: Fully colorless, chromophore-free corundum is uncommon relative to the colored sapphire that dominates the market.
-
Size: At 1.06 ct, this stone sits just above the 1-carat threshold most buyers treat as the minimum for a visible engagement-ring center stone; most white sapphire on the market is smaller.
-
Treatment: This stone is untreated, while diffusion treatment and coating are common shortcuts used elsewhere in the white sapphire market to improve colorlessness.
-
Clarity: Graded Eye Clean, with no inclusions visible under normal viewing conditions.
-
Documentation: Graded by AGCL - Gem Lab; no report number is recorded in this stone's product data.
-
Combined effect: An untreated, eye-clean, above-1-carat radiant-cut white sapphire narrows an already small category three ways at once — most comparable stones on the market fall short on treatment status, size, or cut quality.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
View under both daylight and warm indoor light — the radiant cut's brilliant faceting returns light differently than a step or round brilliant cut, so check sparkle under the lighting you'll wear it in most.
-
At 6.75 x 5.08mm, this rectangular radiant outline needs a four-prong setting sized for its dimensions rather than a round-stone mounting.
-
When comparison-shopping, confirm treatment status in writing — coated or diffusion-treated white sapphire is common in the market, and this stone carries neither.
-
Weigh the scarcity noted above, since an untreated, eye-clean white sapphire above 1 carat is harder to source than the broader white sapphire category.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.

Why Choose this 1.06 ct Radiant White Sapphire?
White sapphire's case for engagement ring use is straightforward: it is the hardest colorless gemstone available other than diamond, it is untreated (no coating, no filling, no enhancement), and it requires no special care protocols. The radiant cut at just over 1 carat produces a stone with good face-up surface area and a modern silhouette that suits contemporary settings. Untreated colorless sapphire is more common than untreated colored sapphire, but this stone's clarity and colorlessness are still hand-selected.
