Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities. A trace of iron in citrine’s structure is responsible for its yellow-to-orange color. Citrine was first appreciated as a golden-yellow gemstone in Greece between 300 and 150 BC, during the Hellenistic Age. Natural citrines are rare; most commercial citrines are heat-treated amethysts or smoky quartzes. Along with topaz, citrine is a birthstone for November. It’s also recognized as the gem that commemorates the thirteenth anniversary. Brazil is the leading producer of citrine, with much of its production coming from the state of Rio Grande do Sul. The name is derived from the Latin word citrina which means "yellow" and is also the origin of the word "citron". Sometimes citrine and amethyst can be found together in the same crystal, which is then referred to as ametrine.Citrine has been referred to as the "merchant's stone" or "money stone", due to a superstition that it would bring prosperity.
*CARE (Citrine)*
Ultrasonic: Usually safe
Steamer: Risky
Heat: Fair; color change may occur with heat
Chemicals that harm: Hydrofluoric acid, ammonium fluoride can damage.
Best; Warm, soapy water and then gently clean with a soft brush. Dry with a soft cloth or air dry.
*CLARITY CHART*
IF – Internally flawless; free of inclusions
VVS – Very, very slight inclusions; microscopic inclusions barely
seen under a loupe with 10x magnification
VS – Very Slight inclusions; visible inclusions that can be seen under magnification and sometimes also with the unaided eye.
SI – Small inclusions; inclusions that are obvious under magnification and to the unaided eye.
I – Heavy or large inclusions obvious to the naked eye
All gemstones listed here have been cut by myself. I work exclusively with a precision machine when faceting gemstones. This allows extra brilliance and appeals only seen in precision-cut gems. Gemstones are cut at their correct refractive index using digital precision, this facilitates making the correct facet angles allowing the maximum amount of light to enter and reflect back up through the table. This allows optimum brilliance according to each gemstone's individual refractive index. Special care in polishing ensures that the faceted gem is showcased in all its brilliance. The introduction of precision faceting machines has revolutionized the art of gem cutting allowing the gem cutter to unveil the inner beauty of every single gemstone like it has never been done before. The cut of a gem is one of the main values of a gemstone and each gemstone requires special attention in order to unveil its potential beauty. If you're looking for that extra special stone, I hope you find it here.
Sincerely,
Doug

Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
