How a lot does a one carat ruby value? [Video]


Within the video tutorial I attempted to clarify the strategy I take advantage of to find out “How a lot does a one carat ruby value?”

One carat ruby costs can vary from US$10 to US$12,000

The tactic I used to find out the worth is by first categorizing the stone primarily based on the 4Cs + OT technique.

The six standards I’ve summarized in bullet kind beneath:

HOW TO DETERMINE A VALUE OF A RUBY? 

WHAT ARE 4C’s + OT

Particulars for every standards is supplied beneath:

RUBY’S COLOR RANGE

Hue is the colour vary.  Examples of Ruby’s hue are

  • Purple
  • Purplish Purple
  • Orangish Purple
  • Pinkish-Purple

Saturation is the depth of the hue introduced in a ruby

  • 100% is pure colour or 0% is grey colour

Tone is how mild or darkish a gemstone is

  • Very mild (nearer to the white vary) or Very Darkish (nearer to the black vary)

The best colour vary for a ruby is pink hue, high-intensity saturation & medium tone.  Within the commerce that is referred to as ‘Pigeon Blood Rubies.’ These are the costliest rubies.

RUBY’S ORIGIN & TREATMENT

Origin from Most Costly to Much less Costly

  • Burma (Myanmar)
  • Thailand, Cambodia
  • Mozambique, Madagascar
  • Kenya, Tanzania
  • Afghanistan & Pakistan

The value of origin is set by the “origin’s model,” quantity of provide the mine is producing and the standard of gems popping out from that exact mine.

Therapy – Extra Therapy the Cheaper it’s. Rating in Pricing

  • Unheated & Untreated 100% Pure Ruby
  • Heated Ruby
  • Heated Flux-healed Rubies
  • Lead-Glass Crammed Rubies

Please notice, NOT all 100% untreated or unheated rubies are costly.  We nonetheless should consider different standards to find out the value.  

RUBY’S CLARITY RANGE

Inclusions – Eye Clear to Included

Ruby Clarity Range base on amount of inclusions

Fewer inclusions the costlier the ruby is.  The extra inclusions a ruby has the extra it hurts gem look and subsequently impacts the value.

Transparency – Clear to Opaque

Ruby Transparency Range

Extra clear the ruby’s crystal is the costlier it’s.  Opaque rubies are thought-about very low cost because the crystal will not be clear and subsequently hurts the rubies’ fireplace & sparkle.

RUBY’S CARAT WEIGHT and CUT GRADE

Carat Weight (Greater the costlier)

The larger the ruby the extra pricer it will get.

Reduce Form & Grade

Octagon, spherical and square-cut rubies, generally, are costlier than frequent oval or cushion minimize rubies.  Marquise and pear form minimize rubies are normally cheaper.  The most affordable minimize rubies are cabochons (assuming they aren’t a ‘star’ ruby).

By way of minimize grade, the best minimize vary is ‘proportional.’  Nonetheless, minimize grade will not be thought-about as essential as colour vary, carat weight, origin & remedy.

IN CONCLUSION

As soon as we all know the above standards we are able to then begin evaluating the 5 rubies within the video.

The abstract of the 5 rubies which I in contrast within the video (from left to proper) is supplied beneath.  I additionally included yet one more ruby which I didn’t talk about within the video however is one most costly one carat ruby we’ve got offered lately.
