Here is the one thing to really remember about diamonds...
98% of a diamond’s fire and brilliance is created by the quality of its cut and proportions, not its clarity, color, or size. Its proportions, polish, and the symmetry of its facets are primary to its radiance. None of the other factors, color, clarity, or carat weight, have more of a dramatic effect on a diamonds beauty than the cut... Subtle and minute structural differences of half a millimeter or less will determine whether a diamond will be full of Brilliance or dull and lifeless.
We choose to use Excellent cut diamonds for this purpose alone.
About the diamonds we use
At Titanium Rings Studios we select some of the finest stones. The diamonds are Excellent Cut Diamonds, Vs1 - Vs2, G - H in color.
When purchasing a diamond of over 1/2 carat, we recommend a GIA certified diamond. Certified diamonds can be insured against loss or damage. There is an additional charge of $150.00 for this certification.
At Titanium Rings Studios, we have access to a full range of high quality certified diamonds and stones at very reasonable prices.
Diamond Sizing Chart
Most of our diamond rings are made using smaller diamonds flush set into the band. This makes them affordable as well as easy to wear. Below is a chart to use for converting millimeter measurements to decimal and carat weight.
|Mm Width||Decimal Width||Weight|
|1.0mm||.039 inch||.005 carat|
|2.0mm||.079 inch||.03 carat|
|3mm||.118 inch||.10 carat|
|3.5mm||.125 inch||.16 carat|
|4mm||.158 inch||.23 carat|
|4.5mm||.173 inch||.35 carat|
|5mm||.197 inch||.47 carat|
|5.5mm||.205 inch||.63 carat|
|6mm||.236 inch>||.80 carat|
|6.5mm||.255 inch||1.00 carat|
Diamonds are rated from D (whitest) to Z (Brown).
Nearly colorless G-H-I-J
Faintly tinted, usually yellow K-L-M
Lightly tinted, usually yellow, tint can be seen with the naked eye. N-O-P-Q-R
Tinted, usually yellow, may progress to brownish. Tint visible to the naked eye, even when mounted. S-T-U-V-W-X-Y-Z
The closer you are to D the higher the cost. An engagement diamond is typically between D and H in Color.
The cut of a diamond has the largest affect on its brilliance, "excellent cut" diamonds are preferred.
Proportions Control The Brilliance: FLAWLESS (FL) describes a diamond in which a skilled observer, under favorable lighting conditions, can not see any internal imperfections (inclusions) or surface scratches, after thorough examination with a microscope at ten power magnification or with a 10x corrected loupe. Internal graining is permitted, provided it does not draw any color or texture and is not observable through the crown or top. Small extra facets on the pavilion (bottom) near the girdle (ridge between crown and pavilion) are ok, provided they are not visible when viewed from above. So are small naturals, if they are confined to the girdle and do not flatten the girdle outline.
How big is the diamond?
Larger diamonds often cost much more per carat due to their size and rarity. There are 100 points to a carat. A 50 point diamond is one half carat. (There are five carats to a gram.)
Diamonds are generally rated as to how pure they are and how many inclusions (fractures) they have:
F= Flawless or IF= Internally Flawless
VVS= Very, Very Slightly Included
VS = Very Slightly Included (Also VS1 and VS2 are used)
SI = Slightly Included
I = Included (Typically avoided)
Usually, the minimum acceptable as a wedding diamond between 1/2ct to 1ct (unless you can afford more) would be VS1 or VS2.
INTERNALLY FLAWLESS (IF): Describes diamonds which have no internal characteristics observable under the same conditions as previously described, but which have minor surface blemishes that do not penetrate the diamond. Internal graining is permitted, provided it does not draw any color or texture. Surface grain lines are permitted provided they are not too thick or numerous as to detract from the beauty of the diamond.
VERY, VERY SLIGHTLY INCLUDED (VVS-1 & VVS-2): Describes diamonds that have very, very small inclusions that are difficult for a trained observer to detect under the aforementioned conditions. Colored or textured graining is permitted, provided it is not observable through the crown. Note: Because the inclusions in such a diamond are so minute, we usually locate them under 30 - 40x magnification and work our way down.
VERY SLIGHTLY INCLUDED (VS-1 & VS-2): Describes diamonds with very small inclusions that can be difficult to detect under the aforementioned conditions. With the exception of very large diamonds and occasionally emerald cut diamonds, these inclusions are rarely visible to the unaided eye.
SLIGHTLY INCLUDED (SI-1, SI-2 & SI-3): Describes diamonds with small inclusions that are usually obvious under the aforementioned conditions. Minor or very small inclusions can sometimes be detected in diamonds graded as SI-2 or SI-3 with the unaided eye after being located under 10x magnification.
