Key Features of a Top-Quality Bi-Color Tourmaline (5.40 ct)
1. Carat Weight
5.40 ct is considered a large size for tourmaline, especially if it’s high quality.
Larger bi-color tourmalines are much rarer and more valuable.
2. Bi-Color
“Bi-color” tourmaline typically features two distinct colors within a single crystal—common combinations include:
Pink and green (e.g., watermelon tourmaline)
Blue and green
Red and yellow
The value increases if the color transition is sharp and natural (not blended or muddy).
3. Quality Grading
Top-quality tourmaline would exhibit:
Excellent clarity (eye-clean or near flawless)
Vivid, saturated colors
Natural origin (not treated or enhanced)
Expert cut that maximizes brilliance and shows off both colors distinctly
4. Shape and Cut
Common cuts: Emerald, shapes that highlight the bi-color zoning.
Precision cutting enhances the contrast between the two colors.
5. Origin
Premium bi-color tourmalines often come from:

The colors in the photo have been heavily edited; the seller tried to hide the crack/flaw in the picture. This is a dishonest seller. I do not recommend anyone buy from this seller.

Perché gli utenti superano se stessi?
Quando viene fatta un'offerta, questo è l'importo massimo che una persona è disposta a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto dell'offerente, aumentando gradualmente l'offerta fino al massimo per mantenere la sua posizione di miglior offerente.
Quando c'è un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente piazzando offerte per l'offerente in base alla sua offerta massima. Questo potrebbe sembrare come se gli offerenti stessero superando se stessi, ma è semplicemente il risultato del sistema che aggiorna l'offerta per riflettere il limite massimo degli offerenti.
