HRD Antwerp examined two HPHT-grown diamonds brought for analysis of the 4 C's. A 1.04 ct brilliant diamond was determined to be D color grade, SI2 clarity grade, and type IIb. A 1.14 ct radiant cut diamond was determined to be fancy vivid orange-yellow color, VS2 clarity grade, and type Ib. Spectroscopic analysis revealed growth structures characteristic of HPHT diamonds and that the diamonds displayed phosphorescence. Both diamonds were concluded to be HPHT grown.
Price elasticity of demand refers to how responsive the quantity demanded of a good is to changes in its price. There are three methods to measure price elasticity: percentage method, total-outlay method, and geometrical method. The percentage method uses a formula to directly calculate elasticity. The total-outlay method examines how total expenditure changes with price changes to determine if demand is elastic or inelastic. Geometrical representation shows demand curves for different elasticity scenarios like perfectly inelastic, unitary, and perfectly elastic demand. Price elasticity can be classified as zero, less than one, equal to one, greater than one, and infinity depending on how quantity demanded responds to price changes.

The document summarizes a study on parking and traffic issues at Tennessee State University. It analyzed current parking needs and projected future demand. Data was collected on parking lot usage and vehicle turnover rates. The study determined that building two parking garages could help but would not fully solve the shortage of parking. Alternative solutions like a park and ride area and incentivizing public transportation were also proposed. Road designs around campus were analyzed and redesigned to improve traffic flow with features like additional lanes and stop signs. While a parking garage was part of the solution, long term solutions needed to address reducing the number of vehicles parking on campus.

Various spectroscopic techniques were used to analyse the two stones:
- FTIR absorption spectroscopy
- UV-VIS absorption spectroscopy
- Photoluminescence spectroscopy
- EDXRF spectroscopy
- Diamond ViewTM
imaging
FTIR absorption spectra (Figure 1) show that the colourless diamond is type IIb whereas the
yellow diamond is type Ib.
Figure 1: FTIR absorption spectra. Left: spectrum of the brilliant 1.04ct indicating that it is a type IIb. Right: FTIR spectrum of
the radiant cut 1.14ct showing that it is type Ib.
The absorption spectra of the UV-VIS measurements are shown in Figure 2.

Diamond ViewTM
imaging reveals cuboctahedral growth structures which are characteristic for
HPHT grown diamonds (Figure 3). Both stones display phosphorescence.
Figure 3: Diamond View images of the HPHT grown diamonds show a cuboctahedral growth pattern. Top: brilliant 1.04ct.
Bottom: radiant 1.14ct.
Based on all the results it can be concluded that both diamonds are indeed HPHT grown
diamonds.
