Chemistry and Treatments
The more you know about the origin and physical properties of precious stones, the easier it will be to choose the best stone for jewelry or investment.
Reasons Behind the Color of Spessartines
Spessartine gets its orange and red hues from manganese replacing aluminum in the mineral structure. More manganese increases color saturation.
- Natural Spessartines – 0.1% to 5% manganese
- Deep red gems – approximately 5% manganese
- Vibrant orange Mandarin garnets – up to 20% manganese
Clarity Enhancements
Filling cracks or fractures in gemstones with clear resin can improve their overall clarity. A slight enhancement is acceptable for loose gemstones, provided they are fairly displayed to potential buyers.
A telltale indicator of enhancement can be seen in the visible flow lines and unnatural bright areas when observing a stone using optical spectroscopy.
Color Treatments
Heat treatment lightens the tone and intensifies saturation. This enhancement is routine for commercial stones. Our store in New York City has treated gems available in stock. We warn our buyers about all treatments and provide a full service to choose the best Spessartine garnet to match your priorities – from untreated gems to improved clarity jewelry stones.
To test if colors were enhanced or not, experts use spectroscopy that reveals overheating.
Grading Reports
Lab reports from GIA, AGL, or Gübelin confirm no modifications for collectors seeking untreated museum-quality stones.
Investing in Spessartine Garnet
Investing in Spessartine garnet requires an eye for quality and understanding of market trends. Third-party certification and appreciating market values confirm these captivating gems merit investment-grade status.
Necessary Certification
Reputable grading reports verify critical metrics for premier quality:
- Color – Vibrant saturation
- Clarity – Free of detracting inclusions
- Cut – Fine proportions to maximize color
- Carat weight – Large sizes
- No modifications – Crucial for high value
Trustworthy labs are:
- GIA
- AGL

Reports confirm no treatments and document measurable attributes like dimensions and carat weight.
Upward Value Trajectory
The rare and vibrant Mandarin oranges, as well as fine reds, are driving up prices as supplies dwindle.
Auction prices have climbed over 80% since 2017, driven by expanding demand in the Chinese and US markets. The price per carat of a Mandarin orange has exceeded $14,000 in 2022. This trend shows the investment potential of spessartine.
Building a Collection of Gems in New York City
Top-quality certified museum pieces offer enduring investment value. Target untreated loose gemstones. It’s better to invest in vibrant orange/reds over 3 carats with clean clarity.
Proper certification unlocks Spessartine garnet’s potential as a rare and remarkable alternative gem destined for wider investment audiences.
