Best price for diamond replacement

4C’s explanation

Brilliant Cut replacement 58 Facets

Carat weight is on the main reason that the price will be worth more. Diamonds, precious gems and Pearls are weighted in carats with one carat weighing about 200 mg, Carat come from the Italian carato, which has got an Arabic origin  Qirat.

Just as one Pound (sterling) is divided into 100 pennies, a carat is divided into 100 points which means that a diamond of 50 points weighs 0.45 carats but two diamonds with the same weight  might have different price for replacement.

In order to be able to compare two diamonds the 4Cs is a key factors, so in that case clarity, color and cut must be taken in consideration. Especially if the round diamond missing out, those points have to be respected.

Because diamonds are created deep within the earth, most diamonds contain unique birthmarks called inclusions (internal) and blemishes (external).

Using the international diamond Grading System, created by GIA, diamonds are given a clarity grade that ranges from flawless (FL) to diamonds with more prominent inclusions (I3). I2 have more and I3 are heavily included.

Every diamond is unique as a human been, none are absolutely perfect even though some come close even under 10x magnification known as flawless diamonds, they are exceptionally rare.

Pear shape (57 facets) replacement

To define what’s the Color of the diamond? It’s something that we cannot see. D,E and F are considered colorless. G, H and I are considered Near colorless.

Diamonds which are found in online jewellery stores run from colourless to near-colorless with slight hints of yellow or Brown.e

The only exceptions are the fancy-color diamonds that lie outside of this range, such as fancy -yellow, blue, pink and green diamonds to name a few.

Emerald Cut diamond replacement (50 Facets Cut)

Cut fuels the diamond’s fire, sparkle and brillance. The Better the proportions of a diamond are the more Fire, Sparkle, Scintillation, and Brilliance it will have. That’s a key factor in term of quality diamond. 

Ideal cut diamonds are rarer so obviously better quality. Ideal cut diamonds have a table which varies from 52 % and 57%.

Though extremely difficult to analyse, the cut of a diamond has three attributes: brightness (  light reflected from a diamond), fire (the dispersion of light into the colours of the spectrum) and scintillation (the light flashes or sparkle when a diamond moves).
