925 Bracelets rangli gemlar daraxti narxini aniqlaydigan ulgurji omillar: Karat va ravshanlik

Joylashtirilgan bilan Kador

We all understand that diamonds have the so-called 4C as the evaluation standard. Aslida, these four evaluation standards are the main factors that determine the price for all gems, but the 4C discussed in diamonds has a unique and rigorous evaluation standard. , But for colored gemstones, the evaluation criteria are slightly different.

karatli

Karatli (karatli) is the unit of weight for all gems. Each carat is equal to 0.2 grams and is subdivided into 100 Ballar (Point). Albatta, the higher the carat number, narx qanchalik yuqori bo'lsa, but the relationship between the price of a gem and the number of carats does not increase in the same proportion, bu, the price of a 2 carat gem is not twice the price of a 1 carat gem of the same grade, but far more than twice. The above price is because the larger the rough gemstone, Xardor, and the greater the price jump.

Tozalamoq

Qimmatli tosh ichidagi tozalik darajasi tiniqlik deyiladi, Bu, asosan, marvarid tarkibidagi qo'shimchalar miqdoriga bog'liq. Qo'shimchalar qanchalik kam bo'lsa, ravshanligi qanchalik yuqori bo'lsa. Juda ko'p qo'shimchalar yorug'likning aks etishiga ta'sir qiladi, qimmatbaho toshlarning yorqinligi boshqa rangli qimmatbaho toshlarga qaraganda tiniqlik uchun yuqori talablarga ega, chunki yorug'likni aks ettirish sifati olmoslarning yorqinligiga katta ta'sir ko'rsatadi. Ammo, rangli qimmatbaho toshlar uchun, aniqlik haddan tashqari talabchan bo'lishi shart emas. Birinchidan, chunki rangli qimmatbaho toshlar asosan elementlarning miqdori tufayli rangga ega; ikkinchidan, rangli qimmatbaho toshlarning kiritilishi odatda haqiqiylikning muhim ko'rsatkichidir, chunki qo'shimchalar kelib chiqishni aniqlash uchun eng yaxshi asosni ta'minlaydi.
