NATURAL PINK SPINEL - 2.33CT RECTANGULAR CUSHION (ALGT CERTIFIED, BURMA ORIGIN): ORIGINS & SIGNIFICANCE
A loose, natural pink spinel weighing 2.33 carats, featuring a rectangular cushion mixed cut. The gemstone presents a soft, slightly desaturated violet-pink hue in the provided natural lighting, characteristic of certain deposits in Myanmar. The stone is accompanied by an ALGT (Antwerp Laboratory for Gemstone Testing) Colored Stone Identification Report (#08788992, dated April 18, 2024) which verifies its natural species and suggests Myanmar (Burma) as the geographic origin, with no indications of treatment. The facet junctions appear crisp, and the vitreous luster typical of the spinel species is clearly evident on the table.
STONES ACROSS CIVILIZATIONS
Where This Object Echoes
Mining and reverence of luminescent red and pink gemstones in the Mogok Stone Tract, historically intertwining spinel and corundum.
Ritual & Ceremonial Use
- •Used extensively in high jewelry bespoke commissions as a modern, untreated alternative to pink sapphire.
Meaning Through Time
Considered a variant of ruby ('Balas Ruby') and used as a symbol of royal power.
Recognized and valued independently by connoisseurs as an un-enhanced, highly refractive collector's gemstone.
GEOLOGICAL JOURNEY
CRYSTAL CURIOSITIES
The famous 'Black Prince's Ruby' set in the front of the British Imperial State Crown is actually a massive uncut red spinel.
Unlike rubies and sapphires which are frequently heat-treated to improve color and clarity, spinels are almost entirely unheated in the trade, making them a true 'earth-mined' natural beauty.
HOW SCARCE IS IT?
Genuine antiques with fewer examples on the market. Named makers, documented provenance, or early production examples.
Typical Characteristics
- Limited production
- Named makers
- Growing collector demand
Confidence Factors
- Accompanied by a verifiable ALGT identification report
- Visual characteristics of the stone perfectly match the report's dimensions, cut, and weight specifications
- No visible indicators of synthetic flux or flame-fusion growth in the macroscopic view
GEMOLOGIST'S TAKE
Gemologist & Mineral Specialist
High confidence is based on the presence of a recognized laboratory report that matches the physical characteristics, dimensions, and visual presentation of the gemstone shown.
KEY EVIDENCE
- 1ALGT Report #08788992 specifically citing 2.33ct Natural Pink Spinel
- 2Documented origin suggestion of Myanmar (Burma), which commands a geographic market premium
- 3Rectangular cushion mixed cut visible in both the physical stone and the lab report photograph
- 4No indications of thermal enhancement indicated on the laboratory certificate
WHAT WOULD IMPROVE CERTAINTY
- →Scan the QR code on the ALGT report to verify the certificate matches the lab's online database exactly
- →Examine under 10x magnification (loupe) to observe natural inclusion suites (such as octahedral crystals) characteristic of Burmese origin
- →Check under UV light to observe potential fluorescence patterns typical of Burma pink spinels
CONDITION & GRADE
Condition
The stone appears crisp and free of obvious surface-reaching severe inclusions or abrasions in the provided macro imagery, aligning with a 'mint' condition presentation prior to being set into jewelry.
Surface
Vitreous luster across the crown and table face with clean facet junctions. The surface polish appears to be of high commercial quality, maximizing the stone's inherent high refractive index.
Weight & feel
At 2.33 carats with dimensions of 8.61 x 6.87 x 4.29 mm, this stone has a substantial face-up appearance, benefiting from a slightly shallow depth profile while maintaining respectable brilliance.
GEMSTONE VALUATION
Updated: Apr 11, 2026
Who buys this
Colored gemstone connoisseurs and bespoke jewelers seeking distinct, untreated stones with documented premium origins (Burma).
What increases value
- •Documented Myanmar (Burma) origin
- •Lack of treatments (standard but desirable to have certified)
- •Carat weight over the 2.00ct benchmark
What lowers value
- •Slightly desaturated or greyish modifier compared to highly saturated 'Jedi' pinks
- •ALGT is a respected lab, but not top-tier (like GUBELIN, SSEF, or GRS), which slightly caps the maximum premium at high-end auction.
What makes top-tier examples
- •Vivid, highly saturated neon pink/red color without dark zones
- •Top-tier Swiss laboratory origin reports
Grade & condition
Color saturation and tone primarily dictate spinel value, followed by clarity (eye-clean preferred) and precision of the cut.
Rarity & demand
